Coronavirus Mask Reuse Webinar
April 2 YouTube
Cleanroom, biotechnology,
filtration, and decontamination
experts discussed ways to design
reusable masks and then clean
them. Panelists included Wallace
Leung of Polytechnic University
Hongkong who described the work
he has been doing on nanofibers
for face masks. Reusable masks
using nanofibers have high
efficiency and can be
manufactured at relatively low
cost;
Christine Sun, Waterloo
Filtration Institute compared
medical and N95 filters with and
without electrostatic charges.
The charging greatly increases
efficiency. Decontamination in
an oven only reduces efficiency
slightly.
David Shelep, Paramount Sciences
compared decontamination
technologies and concluded that
H2O2 and several other options
can be immediately employed.
Jim Agalloco, Agalloco
Associates covered use of UV and
CLO2. Nebraska is using a
UV torch to successfully
decontaminate masks.
Barry Garfinkle, Barry Garfinkle
Associates, had a number of
insightful comments relative to
the degree of destruction
needed. There are no
absolutes. A technology
may be less efficient but if the
mask is only slightly
contaminated this may be
sufficient.
Jeff Mathers, Purafil was to
give a presentation on media
which kills viruses. There
was an overbooking situation and
some registrants were not able
to participate. So Jeff will
present in a subsequent webinar.
There were five presentations in
the 2 hour session.

Christine Sun of Waterloo
Filtration Institute provided
guidance on face mask
performance. When
meltblowns are charged the
efficiency is much higher than
when uncharged. She pointed out
that there was only a slight
decrease in efficiency when used
masks were decontaminated in an
oven. Medical and N95
masks were compared. She
emphasized the importance of the
mask fit. The YouTube with her
recoded presentation is also
available
