Amid the ongoing COVID-19 pandemic we are all trying to do our best
to protect ourselves and the people around us from the infection.
Wearing a surgical mask is good enough for protection, but some experts
say that FFP2 and N95 masks, when worn correctly, are significantly more
effective.To get more news about

And
yet these masks, which are classified as particulate respirators, will
only deliver the promised filtering performance if they are a proper
fit. So how are you supposed to know if it’s working right?The first
thing to look for: Does the mask get sucked towards your face when you
breathe in? This is a sign that no air is able to sneak in around the
edges, where the mask touches your face.
If you feel any rapid
flow of air on your cheeks, chin or nose, then the mask doesn’t fit your
face or you haven’t put it on properly, says Peter Paszkiewicz, from a
German institute for occupational health and safety.Unfortunately,
facial hair and scars can often get in the way of the necessary snug fit
and reduce the protective effect. The only solution here is to shave or
try a different mask shape.
To check that no air is leaking out
the sides, wash your hands and hold them over the edges of the mask.
Then try to create pressure by breathing in and out sharply.If you feel
air flowing in or out where the mask meets your face or over the nose
clip, then you’re not protected.
With a perfect fit, a new and
clean FFP2 mask will filter out at least 94% of aerosols from the air
you breathe in. FFP is the European standard for particulate
respirators, similar to the U.S. standard of N95, which filters out 95%
of aerosols.
Still, virologists stress that maintaining proper
social distancing and airing out rooms remain vital, even if you’re
correctly wearing an FFP2 the whole time.
When putting on and
taking off the mask, remember not to touch the rim or the inside. If you
plan on reusing the mask, hang it up so that as much air as possible
gets into the mask and that nothing is touching it.
