												Overview 
												
												
												Demand is Greater than Supply 
												
												The problem with demand is that 
												individuals are buying the masks 
												and causing a shortage for 
												health care workers who need 
												them. If world demand per capita 
												reaches that in China, 5 billion 
												masks would be used each day. 
												This is far above world 
												capacity. Governments will have 
												to regulate mask sales so that 
												those at most risk receive them. 
												Here is the type of analysis 
												which is the basis for our 
												projections. 
												
												 
												
												The mask production depends on 
												meltblown media. A ton of media 
												will make 1 million disposable 
												masks or 200,000 N95 masks. We 
												will be probing the demand and 
												capacity on a continuing basis 
												for each country.   
												
												Sinopec is a major Chinese 
												petrochemical producer. They 
												have teamed with mask makers and 
												are building assembly lines at 
												an astounding rate. The first 
												project completed a few days ago 
												took less than three months and 
												has two non-woven production 
												lines and three spunbond 
												production lines and can produce 
												up to 4 tons of melt-blown 
												fabric for 1.2 million N95 
												disposable masks or 6 tons for 6 
												million disposable masks per 
												day. 
												
												Sinopec plans to start 
												production at eight more 
												meltblown nonwoven fabric 
												production lines in Jiangsu 
												province by the middle of next 
												month. Upon completion, the ten 
												production lines will be able to 
												produce fabric for 3.6 million 
												N95 respirators or 18 million 
												surgical masks every day. 
												
												
												WHO Analyzes Mask Shortage 
												
												The World Health Organization is 
												sounding the alarm about a 
												growing shortage of personal 
												protective equipment (PPE), and 
												the issue extends well beyond 
												the much-publicized medical mask 
												shortage. 
												
												
												Shortage of Masks Sparks 
												Controversies among Countries 
												
												
												South Korea, Germany and Russia announced 
												export bans of masks and other 
												protective gear. They join 
												others nation or territories 
												including India, Taiwan, 
												Thailand, and Kazakhstan that 
												earlier put export bans in 
												place. 
												
												Before the epidemic, China 
												produced about half of the 
												world’s output of masks with 
												daily production of about 20 
												million units, according to 
												state media Xinhua. Factories 
												have since boosted production 
												more than five-fold and are 
												enlisting carmakers to 
												manufacture them. That’s still 
												not enough. 
												
												In the U.S., increased efforts 
												by mask makers 3M Co. and DuPont 
												De Nemours Inc. are also falling 
												short of demand. DuPont, which 
												makes masks and protective body 
												suits worn by first responders, 
												said it’s increased production 
												by more than three times its 
												usual global capacity. 3M, the 
												biggest American manufacturer of 
												N95 respirators, has increased 
												production since the outbreak in 
												China. 
												
												“We’ve added staff, we’ve added 
												overtime, we’ve added 
												technology, we’ve been 
												increasing manufacturing lines,” 
												said 3M spokeswoman Jennifer 
												Ehrlich. “We expect this demand 
												for respirators and other 
												supplies to continue to outpace 
												supply for the foreseeable 
												future.” 
												
												The dependence on China and a 
												few other countries for masks 
												has some calling for a rethink 
												of supply chains. The World 
												Medical Association, which 
												represents physicians, wants 
												governments to establish 
												factories in major markets like 
												the European Union and the U.S. 
												to ensure adequate supply of 
												critical drugs, vaccines and 
												other medical necessities. 
												
												The U.S only has about 1% of 
												the 3.5 billion masks it needs 
												to combat a serious outbreak, 
												Health and Human Services 
												Secretary Alex Azar 
												has said. The country plans to 
												buy 500 
												million surgical 
												masks and N95 respirators for 
												the national stockpile. 
												
												South Korea said on March 5 that 
												it will bolster its control over 
												the production of key materials 
												used for protective masks, as 
												the country is struggling to 
												expand the supply of sanitary 
												products amid the spread of the 
												novel coronavirus here. 
												
												The country will ban all exports 
												of melt-blown nonwoven fabric 
												filter, the key material 
												essential for the production of 
												protective masks, although 
												exceptions can be granted. The 
												country will help companies 
												expand their production 
												capabilities as well, while 
												reaching out to other countries 
												to import the fabric. 
												
												 
												
												Sinopec Moving from Resin to 
												Mask Supplier 
												
												China Petrochemical Corp known 
												as Sinopec Corp,  put its 
												first melt-blown non-woven 
												fabric assembly line into 
												operation at its Yanshan factory 
												in Beijing on March 6. The 
												Yanshan factory is a converted 
												3600 square meter old warehouse 
												that has found new life as a 
												global production base following 
												the challenges brought by the 
												coronavirus outbreak.  
												
												The 14,400-ton capacity Yanshan 
												facility is one of Sinopec's 
												two melt-blown non-woven fabric 
												assembly bases and is co-managed 
												with China National Machinery 
												Industry Corporation. The base 
												has two non-woven production 
												lines and three spunbond 
												production lines and can produce 
												up to 4 tons of melt-blown 
												fabric for 1.2 million N95 
												disposable masks or 6 tons for 6 
												million disposable masks per 
												day. 
												
												The new facility also takes 
												advantage of Sinopec's 
												integrated upstream supply-chain 
												by sourcing local materials from 
												Yanshan and support from the 
												on-site synthetic resin 
												production line.  
												
												"It normally takes about half a 
												year to complete the 
												construction of a 10,000-ton 
												melt-blown fabric factory - We 
												have done it in 12 days, 48 
												hours ahead of schedule. In a 
												challenging time like this, 
												saving 48 hours means that we 
												can produce an extra 12 million 
												disposable masks," said Lv 
												Dapeng, Spokesperson of Sinopec 
												Corp. 
												
												The largest medical material 
												supplier in China, Sinopec is a 
												significant supplier of 
												polypropylene, a key component 
												in the production of disposable 
												masks for medical use. The new 
												assembly line will ensure a 
												stable supply of medical 
												supplies, such as masks and 
												clothing, can be distributed 
												across the nation and 
												worldwide.  
												
												"We are privileged to support 
												those who are protecting us from 
												the virus. Sinopec will utilize 
												all of our resources to ensure 
												supplies to the frontline are 
												guaranteed," said Lv.  
												
												Sinopec plans to start 
												production at eight more 
												meltblown nonwoven fabric 
												production lines in Jiangsu 
												province by the middle of next 
												month after commissioning two 
												new units in Beijing on 
												Saturday. Upon completion, the 
												10 production lines will be able 
												to produce fabric for 3.6 
												million N95 respirators or 18 
												million surgical masks every 
												day, it said. 
												
												The price of meltblown nonwoven 
												fabric has been surging since 
												the outbreak started, from 
												around 12,000 yuan ($1,726) per 
												ton to 400,000 yuan per ton. The 
												price surged to 700,000 yuan per 
												ton on Feb 24, The market price 
												of the product is expected to 
												gradually come down from its 
												current peak, said Li Li, 
												research director at energy 
												consulting company ICIS China. 
												
												China's centrally administered 
												State-owned enterprises have 
												been accelerating work in the 
												production of meltblown nonwoven 
												fabric to help the anti-epidemic 
												fight, with daily production 
												capacity of meltblown nonwoven 
												fabric reaching 26 tons as of 
												March 6 and the same is expected 
												to grow significantly in the 
												coming weeks, said the 
												State-owned Assets Supervision 
												and Administration Commission. 
												
												Chinese Car Companies become 
												Mask Suppliers 
												
												Chinese automakers BYD Co. and 
												GAC Motor Co. are preparing to 
												produce face masks and 
												disinfectants to help motorists 
												and the public ward off the 
												ongoing coronavirus outbreak in 
												China. 
												
												Two BYD plants in the south 
												China province of Guangdong were 
												expected to be churning out 5 
												million face masks and 50,000 
												bottles of disinfectants a day 
												by the end of the March. The 
												first batch of face masks and 
												disinfectants was donated to 
												drivers of public buses, taxis 
												and ride-hailing fleets as well 
												as volunteers fighting the viral 
												outbreak.  
												
												Masks and disinfectant will also 
												be sold to the public at factory 
												prices. The two plants will keep 
												producing masks and disinfectant 
												until the end of the epidemic. 
												The company is currently 
												mobilizing employees to find 
												sources of meltblown cloth. It 
												is not only BYD that lacks 
												melt-blown cloth. Many companies 
												preparing to produce masks 
												across borders also face this 
												problem. 
												
												GAC, a state-owned automaker 
												based in the south China city of 
												Guangzhou, has dispatched a team 
												of employees to an equipment 
												manufacturer in nearby Dongguan 
												to learn how to produce face 
												masks.  
												
												Hainan Ganlin Technology Group 
												is a company engaged in 
												agricultural business. The 
												general manager of the company 
												said that because farmers could 
												not find sufficient and reliable 
												masks, which affected 
												agricultural production, he 
												purchased mask machines to build 
												production lines, hoping to 
												connect with sufficient 
												meltblown cloth resources. At 
												present, the company has 
												contacted Sinopec but found that 
												meltblown cloth is still scarce. 
												
												Chinese Supply vs Demand 
												
												Medical surgical masks and N95 
												masks generally use a multilayer 
												structure, referred to as the 
												SMS structure: a single layer of 
												spunbond on the inside and 
												outside; the middle is the 
												meltblown layer, generally 
												divided into single layers or 
												multiple layers. 
												
												Among them, the outer layer is a 
												non-woven fabric with a 
												waterproof treatment, which is 
												mainly used to isolate the 
												droplets sprayed by patients; 
												the middle melt-blown layer is a 
												specially-treated melt-blown 
												non-woven fabric with good 
												filterability. Shielding, 
												thermal insulation and oil 
												absorption, is an important raw 
												material for the production of 
												masks; the inner layer is 
												ordinary non-woven fabric. 
												
												Although the spunbond layer of 
												the mask and the meltblown 
												layer are non-woven fabrics, and 
												the raw materials are 
												polypropylene, the manufacturing 
												process is not the same. 
												
												Among them, the diameter of the 
												spunbond layer fibers on the 
												inner and outer sides is 
												relatively thick, about 20 
												microns; the fiber diameter of 
												the meltblown layer in the 
												middle is only 2 microns, and it 
												is made of a polypropylene 
												material called high-melt-finger 
												fiber. 
												
												China is the world’s largest 
												non-woven fabric producer. The 
												production volume of non-woven 
												fabrics in 2018 was about 5.94 
												million tons, but the output of 
												meltblown non-woven fabrics was 
												very low. 
												
												According to the statistics of 
												China Industrial Textile 
												Industry Association, the 
												production technology of China’s 
												nonwovens industry is mainly 
												spunbond. In 2018, the output of 
												spunbond non-woven fabrics was 
												2.971 million tons, accounting 
												for 50% of the total output of 
												non-woven fabrics, mainly used 
												in sanitary materials and other 
												fields; meltblown processes 
												accounted for only 0.9%. 
												
												From this calculation, in 2018, 
												the output of domestic meltblown 
												nonwovens was 53,500 tons / 
												year. These meltblown cloths are 
												used not only for masks, but 
												also for environmental 
												protection materials, clothing 
												materials, battery separator 
												materials, wiping materials, and 
												the like. 
												
												During the epidemic, the demand 
												for masks has increased 
												significantly. According to the 
												data of the Fourth National 
												Economic Census, the total 
												employment of domestic legal 
												entities and self-employed 
												households is as high as 533 
												million people. Based on one 
												mask per person per day, at 
												least 533 million masks are 
												required per day. 
												
												Chinese Melt Blown Media Supply 
												and Suppliers 
												
												Data from the Ministry of 
												Industry and Information 
												Technology shows that currently 
												the maximum daily production 
												capacity of domestic masks is 20 
												million as of January 2020. 
												
												The gap in masks is huge, and 
												many companies are beginning to 
												produce masks across borders. 
												According to the data of Tian’s 
												Eye Examination, based on the 
												changes in industrial and 
												commercial registration 
												information, from January 1 to 
												February 7, 2020, more than 
												3,000 companies across the 
												country have added “masks, 
												protective clothing, 
												disinfectants, thermometers, 
												medical equipment, etc.” 
												
												Compared to mask manufacturers, 
												there are not many manufacturers 
												of meltblown nonwovens. 
												
												The current companies producing 
												meltblown nonwovens are Hengtian 
												Jiahua Nonwoven Co., 
												Ltd. (hereinafter referred to as 
												Hengtian Jiahua), Xinlong 
												Holdings, Sinopec, Shandong 
												Dongying Junfu Non-woven Co., 
												Ltd., and Quantum Golden Boat 
												(Tianjin) Nonwoven Co., Ltd. 
												
												Hengtian Jiahua is a non-woven 
												fabric manufacturing enterprise 
												jointly invested in by China 
												Hengtian Group and Xiantao 
												Jiahua Plastic Products Co., 
												Ltd. China Hengtian Group is the 
												world’s largest textile 
												machinery manufacturing company. 
												
												On January 27, Hengtian Jiahua 
												announced that the company’s 
												entire plant was put into 
												production and the output 
												reached 120 tons/day. The 
												products include non-woven 
												fabrics for face masks, 
												non-woven fabrics for meltblown 
												filtration, and non-woven 
												fabrics for bottom surfaces. 
												
												Xinlong Holdings was established 
												in Hainan Province in July 1993 
												and listed on the Shenzhen Stock 
												Exchange in 1999. It claims to 
												be the first listed company in 
												China’s non-woven industry, and 
												it is also the construction and 
												operation unit of the “National 
												Nonwoven Materials Engineering 
												Technology Research Center”. 
												
												Xinlong Holding’s meltblown 
												non-woven workshop for mask 
												bacteria filtering runs 24 hours 
												to ensure the supply of raw 
												materials to downstream mask 
												manufacturers. Xinlong Holdings 
												owns production bases in Hainan, 
												Hubei and Hunan. 
												
												Shandong Dongying Junfu 
												Nonwovens Co., Ltd. is a 
												non-woven fabrics manufacturing 
												enterprise jointly established 
												by Hong Kong Tianyi Industrial 
												Co., Ltd. and Guangdong Junfu 
												Group. The company’s total 
												investment exceeds 100 million 
												yuan, and the goal is to build a 
												large non-woven fabric 
												production base in northern 
												China. 
												
												The company is a meltblown 
												non-woven fabric manufacturer, 
												which mainly supplies raw 
												materials for the production of 
												daily protective masks, medical 
												masks and industrial dust masks. 
												Recently, in order to ensure the 
												production for the epidemic, the 
												company received advance funds 
												from Shandong provincial finance 
												and can use it for half a year 
												without compensation. 
												
												Quantum Jinzhou (Tianjin) 
												Non-Woven Co., Ltd. is also a 
												manufacturer of meltblown 
												fabrics, PP / PET two-component 
												nonwovens and other products. At 
												present, the company has two 
												meltblown cloth production lines 
												with a daily output of 4 tons. 
												
												In addition to large-capacity 
												enterprises, there are also 
												small-scale meltblown non-woven 
												enterprises with a daily output 
												of about 1 ton, such as Dalian 
												Hualun Nonwoven Equipment 
												Engineering Co., Ltd. and 
												Zhejiang Jiarui Filtration 
												Technology Co., Ltd. 
												
												Dalian Hualun Nonwoven Equipment 
												Engineering Co., Ltd. is a 
												company specializing in 
												engineering general contracting, 
												chemical fiber and non-woven 
												engineering design, and 
												equipment manufacturing. At 
												present, the company has 
												invested funds to transform the 
												original two meltblown equipment 
												production lines (production of 
												air filter materials) into mask 
												filter material production 
												lines. Since its upgrade  it has 
												supplied 3.07 million BFE99 
												medical mask filters per day. 
												
												Mr. Huang from Dalian Hualun 
												Nonwoven Equipment Engineering 
												Co., Ltd. told Interface News 
												that the company’s meltblown 
												cloth production is currently 1 
												ton/day and the ex-factory price 
												is 70,000 yuan per ton. 
												
												On February 12, the price quoted 
												by a small meltblown cloth 
												manufacturer to the Interface 
												journalist reached 80,000 yuan 
												per ton. 
												
												On January 28, the client of the 
												People ’s Daily quoted that 
												according to local companies, 
												the market price of melt-blown 
												cloth for filter materials for 
												masks rose from the original 
												18,000 yuan/ton to 29,000 yuan/ton. 
												From this calculation, the 
												market price of meltblown cloth 
												has increased more than 
												threefold recently. 
												
												Dailian Jualiun says that in the 
												next seven days, it  will be 
												able to expand production to 1.5 
												tons-2 tons/day; in the next two 
												months, the output of meltblown 
												cloth will be expanded to 3 
												tons/ day. 
												
												Zhejiang Jiarui Filtration 
												Technology Co., Ltd. also told 
												Interface News that the 
												company’s current meltblown 
												cloth output is 1 ton/day, which 
												can only supply small customers 
												and cannot meet the supply needs 
												of large companies such as BYD.

												ASHRAE Guidance on Coronavirus 
												
												In response to ongoing 
												developments, ASHRAE has 
												released proactive guidance to 
												help address coronavirus disease 
												2019 (COVID-19) concerns with 
												respect to the operation and 
												maintenance of heating,

												air-conditioning systems. The ASHRAE 
												COVID-19 Preparedness Resources 
												webpage provides 
												easily accessible resources from 
												ASHRAE to building industry 
												professionals. 
												
												“The recent escalation in the 
												spread of coronavirus disease 
												2019 is alarming on a global 
												scale,” said 2019-20 ASHRAE 
												President Darryl K. Boyce, 
												P.Eng. “While ASHRAE supports 
												expanded research to fully 
												understand how coronavirus is 
												transmitted, we know that 
												healthy buildings are a part of 
												the solution. ASHRAE’s COVID-19

												Superior Felt and Filtration has 
												Both Meltblown and Needle 
												Punched Media for Masks 
												
												Superior Felt & Filtration 
												manufactures and supplies a wide 
												array of nonwoven synthetic 
												fabrics for the manufacturing of 
												safety & personal protection 
												filters. It is among the top 
												nonwoven synthetic filter media 
												suppliers for medical and 
												emergency response textiles, 
												such as respirators and masks. 
												It is one of the largest 
												manufacturers of micron and 
												sub-micron filter media for 
												respirator and medical 
												applications in the U.S. 
												
												The company offers non wovens that 
												can be utilized in masks, air 
												purifiers, medical equipment, 
												personal safety apparel and 
												cleanrooms that are highly 
												efficient against 0.1 micron 
												particles. The  electrostatically 
												charged high alpha perm melt 
												blown and needle punched 
												products can be easily molded 
												into masks, pleated and die cut 
												to offer protection over 99.9% 
												against 0.1 micron particles 
												which are considered to be the 
												most penetrating particle sizes 
												(MPPS). The electrostatic media 
												offers low air flow resistance 
												for more breathable masks or 
												devices that help reduce fatigue 
												& improve comfort levels. 
												
												Technostat® can also be utilized 
												with breathable laminates, 
												activated carbon and other 
												materials for combined dust and 
												gas filtration. For these 
												reasons, Technostat® is ideal 
												for nonwoven synthetic filter 
												media for respiratory 
												applications. In addition to 
												Technostat® filter media, the 
												company also offers Technostat® 
												Plus – a triboelectric media of 
												needle-punched felt that offers 
												20% improvement in filtration 
												efficiency over standard 
												electrostatic filter media. This 
												nonwoven synthetic fabric 
												produces its triboelectric 
												properties when 2 dissimilar 
												fibers used during the 
												manufacturing process create a 
												charge that enhances filtration 
												capabilities. 
												
												Superior Felt & Filtration also 
												provides electrostatic filter 
												media rolls (electrostatically-charged 
												synthetic needle punch fibers) 
												and melt blown fibers. These 
												nonwoven synthetic fabrics aid 
												in producing some of the highest 
												levels of filtration for health 
												care providers and emergency 
												responders. 
												
												 SWM International says it 
												stands ready to supply 
												converters and manufacturers of 
												face masks with advanced 
												nonwoven materials necessary to 
												meet the global challenge 
												presented by the coronavirus 
												outbreak. 
												
												“SWM has a long history of 
												supplying high-quality media 
												integral to the construction and 
												performance of face masks used 
												in the dental and surgical 
												sectors as well as the 
												industrial sector,” said Bart 
												Sistrunk, SWM’s Commercial 
												Director – Filtration. “Our 
												DelporeTM meltblown 
												media is widely used in face 
												masks because it provides 
												excellent breathability without 
												sacrificing Bacterial Filtration 
												Efficiency (BFE) and its 
												lightweight nature allows for 
												comfortable wear.” 
												
												A leading producer of meltblown 
												media, SWM also offers DelnetTM apertured 
												film, a lightweight nonwoven 
												that is extruded, oriented, and

												for customers who need materials 
												for face mask production,” said 
												Sistrunk. “We are committed to 
												continued support during the 
												current world health emergency.” Air Filtration 
												
												
												Can Coronavirus Spread through 
												HVAC System? 
												
												The CDC does not believe that 
												COVID-19 is likely to be 
												transmitted through duct work. 
												However, several university 
												studies show the opposite. 
												Coronavirus could spread around 
												buildings via air conditioning 
												systems or even on a draft, new 
												analysis has suggested after 
												scientists found traces of the 
												virus in a hospital air duct. 
												The results from swab analysis 
												of the rooms used by three 
												coronavirus patients indicate 
												that the disease may be more 
												contagious than previously 
												thought. 
												
												Even though the patient thought 
												to be responsible was suffering 
												only "mild" symptoms, scientists 
												from the National Centre for 
												Infectious Diseases in Singapore 
												found evidence of the virus in 
												the hospital's air exhaust. This 
												"suggests that small, 
												virus-laden droplets may be 
												displaced by airflows and 
												deposited on equipment such as 
												vents", they said.

												New Air Filtration Needs for 
												Autopsies 
												
												In Iran bodies are piling up at 
												morgues. This presents several 
												challenges. Autopsies on 
												decedents with known or 
												suspected COVID-19 should be 
												conducted in Airborne Infection 
												Isolation Rooms (AIIRs). These 
												rooms are at negative pressure 
												to surrounding areas, have a 
												minimum of six air changes per 
												hour (ACH) for existing 
												structures and twelve ACH for 
												renovated or new structures, and 
												have air exhausted directly 
												outside or through a HEPA 
												filter. Doors to the room should 
												be kept closed except during 
												entry and egress. If an AIIR is 
												not available, ensure the room 
												is at negative pressure with no 
												air recirculation to adjacent

												recirculation unit could be 
												placed in the room to provide 
												further reduction in aerosols. 
												Local airflow control (i.e., 
												laminar flow systems) can be 
												used to direct aerosols away 
												from personnel. If use of an

												Transmission through Cruise Ship 
												Ductwork Diamond - Princess 
												Ductwork Debated 
												
												Anne Schuchat, principal deputy 
												director at the U.S. CDC, says 
												there is no current evidence to 
												suggest that the coronavirus 
												spreads through air-handling 
												systems. Eric van Dijk, employed 
												at Dutch HVAC specialist Heinen 
												& Hopman, agrees it is unlikely 
												for viruses to spread through a 
												ship’s HVAC system due to the 
												way air travels through the 
												system. 
												
												 
												
												The cruise ship Diamond Princess 
												was quarantined in Japan. The 
												ship had 3700 people on board, 
												of which 620 people were 
												eventually infected by the 
												coronavirus. Some of the 
												passengers expressed worries 
												about the virus spreading 
												through the ship’s HVAC (heating 
												ventilation air-conditioning) 
												system to which the CDC 
												responded. 
												
												According to Van Dijk, whose 
												company did not supply the HVAC 
												system for this ship , ‘fresh 
												air is supplied on a cruise ship 
												by several air handling units. 
												The ducts connected to the air 
												handling units provide the 
												public areas and cabins with 
												fresh air. Within these units, 
												air passes through multiple 
												filters, at least EU4 pleated 
												filters.’ EU4 filters belong to 
												the category of coarse dust 
												filters with an over ninety per 
												cent arrestance. 
												
												‘Optionally, these units are 
												equipped with a HEPA filter 
												and/or UV light units to treat 
												polluted air further,’ adds Van 
												Dijk. These filters do not stop 
												viruses from spreading, however. 
												
												Van Dijk explains: ‘The filtered 
												air that enters a cabin is 
												filtered again in a fan coil 
												unit, but these filters are made 
												to fight bacteria, not viruses. 
												Viruses are so small, that you 
												would need a very strong filter. 
												When you need such a strong 
												filter, the air handling units 
												are possibly four times as big. 
												This means that the energy 
												consumption and emissions will 
												be many times higher.’ Not 
												something that is desirable for 
												a cruise ship, as these ships 
												already have a name for being 
												polluters and are working hard 
												to lower their environmental 
												footprint. 
												
												The system on board the Diamond 
												Princess was supplied by MCI 
												Namirei. In a statement, Diamond 
												Princess’ owner Princess Cruises 
												said, ‘the HVAC filtration 
												system on our ships is 
												comparable to those used by 
												land-based hotels, resorts and 
												casinos.’ This probably means 
												this system will also not be 
												able to filter out viruses. 
												
												However, Van Dijk points out the 
												chance of a virus spreading 
												through the HVAC system is still 
												very small. This has to do with 
												the way the air travels. He has 
												drawn the overview which shows 
												that, although not impossible, 
												it is unlikely for a virus to 
												travel from cabin A to cabin B. 
												
												The opposite conclusion was 
												reached by Qingyan 
												Chen, Purdue’s James 
												G. Dwyer Professor of Mechanical 
												Engineering. He has researched 
												the spread of air particles in 
												passenger vehicles and how to 
												track them. His team developed 
												models in the past for showing 
												how the H1N1-A flu and other 
												pathogens travel through 
												aircraft cabins. 
												
												When Chen co-led the Air 
												Transportation Center of 
												Excellence for Airline Cabin 
												Environment Research, his lab 
												made discoveries about 
												the airborne nature of SARS that 
												could inform understanding of 
												the coronavirus. 
												
												He told the media  “It’s 
												standard practice for the air 
												conditioning systems of cruise 
												ships to mix outside air with 
												inside air to save energy. The 
												problem is that these systems 
												can’t filter out particles 
												smaller than 5,000 nanometers. 
												If the coronavirus is about the 
												same size as SARS, which is 120 
												nanometers in diameter, then the 
												air conditioning system would be 
												carrying the virus to every 
												cabin. 
												
												Cruise ships could minimize this 
												problem by just using outside 
												air and not recirculating it.”

												The effectiveness of HEPA and 
												Filtrete filters was addressed 
												by Biosafe Air.  How 
												effective can HEPA actually be? 
												The chart below, adapted from an 
												EPA report lists the MERV rating 
												of filtration material 
												corresponding to the typical 
												contaminant that they address, 
												along with the typical filter 
												type found in the MERV rating 
												group (from HEPA to “HEPA-like” 
												filters). 
												
												Even though the MERV value is 
												strictly performance based, you 
												can still derive some value from 
												the chart below, as it gives you 
												an indicator of the limits of 
												certain types (e.g. higher 
												efficiency pleated filters vs. 
												true HEPA filters). Generally, 
												HEPA is considered the 
												equivalent of a MERV 17. 
												
												Reputable air purifier companies 
												that have filtration-based units 
												should clearly state their MERV 
												rating, or state plainly what 
												the particle size and type of

												Viruses can typically range from

												effective are Pall HEPA filters 
												at removing bacteria and 
												viruses? An independent test 
												laboratory has tested three Pall 
												cabin air filter elements using 
												two different bacteria; 
												Brevundimonas diminuta and 
												Bacillus subtilis and results 
												show that the bacterial removal 
												efficiency of the Pall cabin air 
												filters is greater than 99.999%. 
												Similarly, when challenged with 
												the MS2 Coliphage virus, the

												greater than 99.999% 
												
												 
												
												Pall Aerospace engineers teamed 
												up with scientists from Pall 
												Medical group to develop and 
												validate the microbial removal 
												efficiency of aircraft cabin air 
												filters, following standard 
												practices used in the healthcare 
												and pharmaceutical industries. 
												
												Why cabin air filters do not 
												need an anti-microbial 
												treatment? In free air, most 
												microbes die within a few 
												minutes. Once captured by the 
												filter media, the survival rate 
												of microorganisms in the 
												aircraft environment is very 
												low. Most bacteria require high 
												humidity and a source of 
												nutrition to survive. The 
												conditions typically found in 
												the aircraft recirculation 
												system are 10-15% relative 
												humidity and lack of a source of 
												nutrition. Is there a danger to 
												maintenance personnel by 
												removing used cabin air filters? 
												
												There is no more risk involved 
												in replacing a cabin air filter 
												than carrying out general 
												maintenance on any aircraft part 
												that has been in service for a 
												number of years. Maintenance 
												staff should wear the same 
												personal protective equipment as 
												for other aircraft maintenance 
												tasks which require protection 
												against dust, and per the local 
												regulations. The used HEPA 
												filter should be placed and 
												sealed in a plastic bag. A 
												specific biohazard bag is not 
												required for disposal of the 
												HEPA filter in most 
												jurisdictions. 
												
												
												Peco Filter 
												
												PECO filter effectiveness was 
												evaluated by Consumer Reports.  
												Their analysis follows: 
												
												“Like so many brands that trend 
												on social media, the Molekule 
												Air is available only through 
												the manufacturer’s website—for a 
												whopping $800. It’s the sort of 
												niche product that Consumers 
												Reports wouldn’t necessarily 
												test, but given the buzz it’s 
												generated, “we felt a 
												responsibility to weigh in with 
												test data”. 
												
												“And because the Molekule 
												manufacturer claims to have 
												revolutionized air cleaning with 
												its proprietary PECO technology, 
												we dug a little deeper. Here’s 
												the story of our reporting and 
												our lab tests. 
												
												This acronym is short for 
												photoelectrochemical oxidation. 
												It isn’t new technology, per se, 
												but rather a boosted version of 
												PCO (photocatalytic oxidation), 
												which has been used for decades 
												to clean contaminated air and 
												water.  
												
												A typical mesh filter—HEPA, for 
												instance—captures only airborne 
												particles. PECO and PCO, 
												however, take it one step 
												further and also target gases. 
												It does this by coating filters 
												in a catalyst (PCO usually uses 
												titanium dioxide) that reacts 
												with UV light to oxidize gaseous 
												pollutants and breaks them down 
												into harmless molecules. 
												
												According to the Environmental 
												Protection Agency, PCO air 
												cleaners can break down many 
												types of gaseous pollutants, but 
												not many typically found in 
												indoor air. The process can also 
												react with some pollutants to 
												generate other dangerous 
												byproducts, such as ozone, 
												formaldehyde, nitrogen dioxide, 
												and carbon monoxide. 
												
												Because of these factors, the 
												EPA reports that to effectively 
												and efficiently eliminate common 
												gases and microbes found in 
												homes in a safe manner, PCO 
												technology needs to improve. 
												Molekule says it has done just 
												that. 
												
												“PECO was inefficient in 
												destroying pollutants, so we 
												fine-tuned all the parameters,” 
												says Jaya Rao, Molekule’s COO 
												and co-founder. “PECO 
												innovations happened on many 
												levels: the chemical coating, 
												the filter, as well as the UV 
												lighting.” Working together, she 
												says, these innovations make 
												PECO work faster and more 
												efficiently than PCO, allowing 
												it to destroy gases, bacteria, 
												viruses, and mold spores—without 
												producing any harmful 
												byproducts. Rao declined to go 
												into detail about what the 
												company uses for the catalyst. 
												
												CR tests for particle reduction 
												and not for gas or microbe 
												removal. James Dickerson, CR’s 
												chief scientific officer, was 
												asked whether Molekule’s claims 
												have any merit. 
												
												“Theoretically, PECO could work 
												to eliminate microscopic 
												airborne molecules,” Dickerson 
												says. “But our tests show that 
												the Molekule Air is not 
												proficient at catching larger 
												airborne particles, which 
												ultimately means it’s not 
												getting enough air passing 
												through the system.” 
												
												We put the Molekule Air through 
												our standard battery of air 
												purifier tests, and it almost 
												flunked: We put it into a sealed 
												chamber and injected particles 
												as small as 0.1 micron and up to 
												1 micron into the room—a range 
												that includes dust mite 
												allergens, cat allergens, smog, 
												smoke, and atmospheric dust. 
												(For reference, human hair has a 
												diameter of 100 microns). A 
												particle counter measured the 
												change in air-particle 
												concentration as the machine ran 
												for 15 minutes. As usual, we 
												tested at the highest speed and 
												again at a lower speed. 
												
												The Molekule Air gets a Fair 
												rating for smoke and dust 
												removal at high speed and a 
												Poor—the lowest score 
												possible—at low speed. It is the 
												third-lowest-scoring air 
												purifier of the 48 we tested. 
												The manufacturer says the 
												Molekule Air is sized for rooms 
												up to 600 square feet, but its 
												performance in our tests ranks 
												it among compact models that are 
												designed for small rooms. Based 
												on our lab’s calculated rate at 
												which it can process the air, 
												the Molekule Air wouldn’t be 
												able to handle any room larger 
												than 100 square feet. 
												
												We shared our methodology and 
												findings with Rao, and she took 
												issue with our testing. 
												
												“It’s a very limited assessment 
												of Molekule because 
												instantaneous removal of 
												particles is not the full 
												picture of what air purification 
												looks like,” Rao says. “And 
												while we may be destroying at a 
												slower rate, we’re still doing 
												something much more complicated, 
												which is truly purifying the air 
												at the nanoscale level and 
												making it safer.” 
												
												But if the Molekule Air isn’t 
												pulling enough air into the 
												machine in the first place, it 
												may struggle to clean the air at 
												any scale. “Even if the PECO 
												filter works and it purifies the 
												air of microscopic particles, 
												it’s still not effectively 
												catching the large particles, 
												which are also irritants,” 
												Dickerson says. 
												
												In addition to the Molekule 
												Air’s poor performance in our 
												testing for particle reduction, 
												there’s the price to consider. 
												The Molekule Air costs $800, 
												with an annual cost of $130 for 
												filter replacements, plus an 
												additional $50 a year for energy 
												use, based on our calculations. 
												(The model is not Energy Star 
												certified; unlike the majority 
												of air purifiers we test.) 
												
												It’s also not very quiet, 
												garnering a Fair score for noise 
												on the high-speed setting and a 
												Good score on the low-speed 
												setting. Our verdict? Pass on 
												the Molekule Air and opt for one 
												of CR’s recommended air 
												purifiers. Consumers Report say 
												there  are three models, 
												that perform well in  
												particle removal tests and cost 
												hundreds less. air

												A portable operating theatre has 
												been set up in the car park of 
												one of Australia's biggest 
												hospitals. 
												
												Surgeons at Melbourne's The 
												Alfred Hospital have been 
												performing life-saving 
												procedures in the 'Laminar Flow 
												Operating Theatre' after a storm 
												wreaked havoc on one of their 
												primary theatres. 
												
												Vanguard mobile operating 
												theatres can offer a significant 
												increase in capacity during 
												times of refurbishment or 
												increased clinical need. A 
												Vanguard theatre gives hospitals 
												a reliable, safe answer to 
												capacity pressures across 
												a range of specialties and 
												procedure types. Mobile laminar 
												flow operating theatres have 
												been widely used across the NHS 
												for procedures including hip 
												replacements, knee replacements 
												and joint revisions. Vanguard 
												laminar flow theatre facilities 
												offer HEPA-filtered 
												environmental air that conforms 
												to Grade A EUGMP, with up to 600 
												air changes per hour passing 
												over the patient, and 25 fresh 
												air changes. 
												
												 
												
												The World Health Organization 
												says that managing an epidemic 
												calls for partnerships with 
												service providers who can help 
												healthcare providers such as 
												hospitals add capacity – 
												preferably partnerships that 
												have been established in 
												advance. This means they can 
												call on them more speedily 
												should disaster strike, and 
												everyone knows what’s expected 
												of them. 
												
												So, what else would work? 
												Clearly, building extra hospital 
												or additional clinical spaces 
												from bricks and mortar isn’t an 
												option – so what can be done? 
												Organizations such as Vanguard 
												Healthcare Solutions work 
												alongside healthcare 
												organizations to create extra 
												capacity which is temporary but 
												much more robust and absolutely 
												clinically sound. The 
												environments are not temporary, 
												but they can be temporarily 
												used. 
												
												In an epidemic, units can be 
												quickly deployed to support 
												areas which are struggling to 
												meet the increased demand, or 
												where, if space has been 
												commandeered in one hospital to 
												create a ‘hub’ for the treatment 
												and containment of an epidemic, 
												they can be used to create a 
												more long-term ‘back-up’ in 
												other locations to make up the 
												shortfall – for example for 
												dialysis patients. 
												
												Patients in either instance can 
												be decanted to the mobile 
												solution – whether that is a 
												clinic, a ward or an operating 
												theatre. Or if additional or 
												faster turnaround of sterile 
												equipment is required to meet 
												the increased demand, a mobile 
												central sterilization unit can 
												help to bridge the gap. 
												
												The mobile units create spaces 
												which can be, if necessary, 
												completely separate from the 
												hospital creating an infection 
												control ‘oasis’, or can be used 
												for testing, triage or 
												supporting the ‘walking wounded’ 
												in clinics and wards. They can 
												be used as additional ward space 
												or even, if needed, a welfare 
												area for staff who may have to 
												stay on site for an extended 
												period without going home. They 
												can also be used for additional 
												and self-contained morgue space, 
												minimizing the 
												cross-contamination risk.
