Masks Effective in Reducing
Intake Risk
Researchers in Japan say they have confirmed that
face masks are effective in both retarding the
spread of viruses and reducing the intake of
them. They used actual coronaviruses and
mannequins to reach that conclusion.
The strain found in the minks is the same one
found in humans, the official said, according to the Greek newspaper Kathimerini. The breeder at one of them also tested
positive for the virus.
The 2,500 minks on one farm have since been culled,
the newspaper reported the agriculture ministry
official as saying, after samples from the
animals there tested positive for the virus.
Testing of workers at mink farms in the Kastoria area
found 10 positive cases, the newspaper said. The
trade in mink fur is an important source of
income for the area.
This could be an excellent
conference for those involved with COVID

Cologne for next week. It has now been canceled.
New daily coronavirus cases in Germany hit
a record of 23,542 on Friday, the Robert Koch
Institute for infectious diseases reported,
prompting government spokesman Stefan Seibert to
say measures “were not expected to be relaxed”
by next week.
Federal and regional leaders are due to meet on
Monday to discuss whether the country’s closure
of all gyms and entertainment venues has slowed
the disease’s spread, but the health minister,
Jens Spahn, said it was too early to say.

Plenary Lecture Roaring twenties
in air filtration - driving for a cleaner world
Dr.-Ing. Martin Lehman MANN+HUMMEL GmbH /
Germany
In medias research air filtration
is omnipresent for delivering clean air:
protecting engine and equipment known as engine
filtration, enabling processes and technology
known as industrial filtration, providing
comfort and indoor air quality known as HVAC
filtration. Adding gas adsorption, the domain of
cabin air filtration shows up. However, in this
talk the focus will be on particle filtration. A
bit more than twenty years ago, the digital
revolution in air filtration started. First
realistic simulations of particle collection on
single fibers. First time visualization of the
3D microstructure of a fibrous filter. CFD and
FEA have become a key tool for designing air
intake systems. Nowadays, we are starting to use
AI-based simulation tools for designing air
filter elements. In addition, in the past twenty
years the design of the filter elements changed
significantly. There is no longer a set of just
rectangular or round filter elements. With
evolving production technology, we are now
thinking and designing in flexible design shapes
with concave curvature, oval shape or variable
pleat heights. Customers have become used to
filter elements fitting just right into their
complex 3D design space.
Membrane science and functional
materials Prof. Dr. Liang-Yin Chu, Membrane
Science and Functional Materials Group – Sichuan
University
Functional
membranes are playing paramount roles for
sustainable development in myriad aspects such
as energy, environments, resources and human
health. However, the unalterable pore size and
surface property of traditional porous membranes
restrict their efficient applications. The
performances of traditional functional membranes
will be weakened upon the unavoidable membrane
fouling,

The attached exhibition list
shows that many of the 349 exhibitors have
media, machines, filters, or test equipment
which is relevant.
MANN+HUMMEL
solutions for air hygiene create almost
completely virus-free air indoors. For rooms
without central air conditioning, there is the
stationary air purifier OurAir SQ 2500 which is
suitable for rooms up to approx. 200m² and its
mobile pendant, the OurAir TK 850, which filters
the air in rooms up to 70m². The heart of the
units is its HEPA H14 air filter, which captures
more than 99.995% of viruses, bacteria and
microorganisms. The compact filter, Nanoclass
Cube Pro Membrane, is designed for HVAC systems
working in circulation mode. The H13 filter
achieves a separation rate of 99.95%. All air
filters are equipped with a new ePTFE media with
a 50% lower pressure drop compared to
conventional HEPA air filters based on micro
glass fiber. This makes the filters particularly
energy efficient. The media is fire resistant
tested according EN 13501 as class E and with
that applicable for all HVAC application in
non-residential buildings acc. EN 15423 and VDI
3403-4.
The Palas® respiratory
mask filter test rig PMFT 1000 allows a reliable
control of the filter performance and enhances
quality assurance. The current spread of the new
corona virus CoVid-19 is leading to a massive
increase in demand for respiratory masks
worldwide. Manufacturers of filter media and
respiratory masks are increasing their
production capacities to the maximum. However,
reliable protection is only offered by masks
that have undergone special tests during
production. To support manufacturers, Palas has
introduced the newly developed PMFT 1000
respiratory mask filter test rig, which enables
both quality assurance in production and product
improvement in the development department. A
special advantage of the PMFT 1000 from Palas
compared to other filter test rigs is that
additionally to the penetration by mass, the
exact representation of the separation per size
class of the particles can be detected.
Especially regarding the effectiveness of the
breathing masks for the corona virus (size:
approx. 120 nm - 160 nm), such an exact
measurement of the particle size distribution is
essential. The fractional efficiency is tested,
e.g. the efficiency in the whole size range of
100 nm up to 5 μm (size range spectrometer 100
nm up to 40 μm*). PMFT 1000 is future proof: It
works with any kind of aerosol, it can be used
for all kinds of face masks and is also easy to
handle.
The Hollingsworth & Vose
NanoWave® XT is the new NanoWave® filter media
series designed for use in various filter
configurations for Heating, Ventilation and Air
Conditioning (HVAC) systems in residential and
commercial buildings as well as industrial
applications. Tests have shown that the new
NanoWave® XT series outperforms all other filter
media. It features the highest efficiency in
protecting people and sensitive components
against hazardous PM1 particles as well as
double to triple higher dust-holding capacity
compared to other premium filter media. In
addition, NanoWave® XT significantly reduces the
energy consumption of a building. As much as 30%
of energy consumption of an HVAC system happens
due to the pressure drop in the air filters.
NanoWave® XT media, having up to 40% lower
pressure drop compared to other premium
filtration materials, will significantly lower
the energy consumption of the air filter and
thus of the whole HVAC system. NanoWave® XT
media can be easily and safely disposed of,
without negatively impacting the environment or
causing unnecessary disposal costs. Due to its
unparalleled performance, NanoWave® XT sets new
standards in both filtration performance and
energy efficiency.
ABCR: More and more
microorganisms are coming into focus because of
their health-endangering properties. The
formation of multi-resistant germs is one of the
big challenges for new, sensible solutions. To
equip all surfaces antimicrobial - even in
water-bearing systems - abcr eco_antimic* from
abcr GmbH is a proven alternative. The material
provides an enormously wide range of
applications as a surface-active substance in
respect of incubation time, effectiveness and
duration of action. The substance can be used as
a coating or as part of the matrix and then
shows practically no wear and tear and a
long-lasting effect over several years.
Challenging applications can be found on all
contact surfaces touched by people, e.g. in
hospitals, sanitary facilities, on medical
equipment. A further field of application is the
reduction of biofilms in water-bearing systems.
abcr eco_antimic* has already been successfully
used in various applications. A large number of
patents and the biocide approval exist.
A2Z’S Intelligent Servo driven
Blade Pleater along with the mini pleat
production modules, allows the user to work with
a variety of media including glass fiber as well
as synthetic, with change overs for pleat
depth/pleat pitch, and hot melt patterns on the
fly. The operator can save and access up to
2,500 stored product variations, thus allowing
multiple combinations/part numbers to be
produced. The machine’s unique flexible design
helps filter manufacturers widen their product
range and meet the market’s ever changing needs.
The A2Z Mini Pleat production module can be
added to any existing blade pleater to produce
mini pleat packs with a wide array of media thus
further reducing the filter manufacturer’s
capital expenditure and providing a very
flexible production line. This also makes the
equipment future-proof with the unique ability
to mini pleat a very wide range of media.
Helsatech (Mann + Hummel)
The company Helsatech GmbH is a specialist in
designing and producing air filtration media
based on activated carbon as well as other
adsorbents. Our filtration media are
multifunctional and reliably remove a wide
variety of odors and pollutants from air:
Particles, VOC´s, basic gases like ammonia or
amines and acid gases like H2S, SO2 and NO2.
Formaldehyde is contained as binder or
preserving agent in many plastics, paints,
cloths, floorings and furniture made of flake
boards. Since 2015, it is classified as category
1B which means it can cause cancer in the
nasopharyngeal zone when inhaled. Therefore, we
developed filtration media based on impregnated
activated carbons for the enhanced removal of
formaldehyde from indoor and cabin air. Within
this filtration process, the formaldehyde
molecule is bonded irreversibly to the
impregnation substance. We developed pleatable
media as well as impregnated foams or non-wovens
for V-cells or air purification devices. We also
offer the impregnation on an activated carbon
honeycomb, which results in a filter medium
having high capacity and excellent breakthrough
behavior combined with a very low pressure drop
and thus a low noise level in air purification
devices.
HiFyber:
Antibacterial Nanofiber HVAC Filter Media. The
proper filtration of circulating indoor air
become more important because, today people
spend more than 80% of their daily lives indoors
and The HVAC systems are referred as the
respiratory system of modern buildings. However,
during HVAC operation, the microorganisms may
obtain suitable environmental conditions such as
temperature, moisture level and nutrient to grow
and they can diffuse into the filter components
in the form of bio-aerosols or accumulated dust
and then spread into the indoors. The emergence
of the deadly virus Covid-19 points to the need
to move the efficiency level of indoor
ventilation systems to the next level. Bacteria
or viruses do not move in the air on their own
and are usually accumulated on dust, saliva or
droplets. Airborne-sized particles were
considered to be particles 5 μm in size.
Challenge controls are maintained at 1700 – 3000
colony-forming units with a mean particle size
of 3.0 ± 0.3 μm at “Bacterial Filtration
efficiency(BFE), EN 14683 Standard”. HIFYBER
HVAC products at F7 level can hold more than 90%
of 3 μm particles. It is also possible to
increase the BFE to over 99% with HIFYBER HVAC
products. SPP65-AB is an innovative product that
combines nanofiber with antibacterial
technology. In addition to its high
pleatablility, it has 4 times more air
permeability at the F7 level than
non-antibacterial and widely used glass fiber
products. HIFYBER cleans the air with its
nanotechnological products and also prevents the
growth of microorganisms with its antibacterial
filter media. DHCAE Tools GmbH Hall 8 C48 H
Mikropor:
ASHRAE, mentioned that indoor air handling units
must be restored with new filtration systems
featuring maximum possible efficiency and
portable air purifiers with HEPA efficiency
should be used in indoor environments (“ASHRAE
Position Document on Infectious Aerosols”
published in April 2020). Furthermore, REHVA
(Federation of European Heating, Ventilation and
Air Conditioning Associations) points out that
AHU Filters must have maximum possible
efficiency and should be replaced on a regular
basis. According to the EN1822 standard the
minimum efficiency of HEPA filters are 99.95%
for class H13 at the overall value of most
penetrating particle size (MPPS). Mikropor, has
been offering solutions to the needs of several
different industries and keeps on dominating the
market with its innovative products including
HEPA, ULPA and variety of other HVAC filters and
also next generation Compressed Air Equipments.
The brand new Mia Air (developed by Mikropor)
has the privilege to be the first ever air
purifier to include H13 efficiency class HEPA
Filter in Turkey. Mikropor is delighted and
proud to announce that Mia Air captures up to
99.99% of the smallest airborne particles even
in this ongoing pandemic, supplies clean air to
indoor spaces and offers healthy and peaceful
living quarters to people.
Europlasma:
Nanofics K - a new nanocoating to boost
performance of HEPA filters Plasma is a unique
technology to deposit ultra-thin coatings on all
exposed surfaces of a material or product. It is
increasingly used in manufacturing of filtration
media and elements to achieve functionalities
such as hydrophilic, hydrophobic or oleophobic.
Improvements in process and machine design allow
to deposit the coatings in a very cost effective
way, with a process that is completely dry and
clean. The technology is giving an increasing
number of producers of technical nonwovens,
membranes, mesh or nanofibers a clear
competitive edge. One of the key areas of
interest is the nanocoating of electrets used in
HEPA filters. A new generation of plasma
nanocoatings (Nanofics K) specifically designed
for electrets is launched at FILTECH 2021.
Advances in process chemistry allow to deposit
coatings which boost and maintain filter
efficiency over time, while not affecting the
pressure drop. Latest synthetic innovation -

ensure that each of your respiratory filters
comply with standards such as NIOSH 42 CFR 84,
GB2626, and EN143/EN149.
Topas looks back to a long-term
expertise in the field of development,
construction, manufacturing and installing of
air filter test systems. Based on the new
normative regulations from ISO 29461 we have
been requested by our key customers to offer a
technical solution to test gas turbine filters.
The new GTS 114 is based on the successful ALF
114 test system concept. Therefore it also
follows testing requirements of ISO 16890 and
ASHRAE 52.2. Main new features are related to
increased air flow rates up to 11.000 m³/h in
recirculation mode with test air conditioning.
Furthermore a list of different test aerosols
such as oil droplets, salt and dust particles
can be applied in combination with multiple
measurement technologies such as optical
particle counting, optical photometer or flame
photometer. The major customer benefit will be
the all-in-one solution we propose different
