Some simple science that everyone should learn:
Masks with FFP2 or N95 rating trap particles by using the electrostatic properties of the fibres in the mask.

They don't catch things like a net.
They catch things *like a magnet* - except not just metal objects. Anything tiny.

There's a bullshit bit of disinformation going round that these masks can't trap viruses because viruses are too small.

That's just wrong. It's like claiming that planes can't fly because they're not birds.

It's just wrong on so many levels.

The people who claim that masks can't trap particles that small are either:
ignorant
or
malicious

So they either need to
learn
or
shut up

FFP2+ and N95+ rated masks trap small particles by the use of electrostatic charge.

It's this effect 👇, but on a microscopic scale.

As particles pass through the mask fibres, they are drawn to the fibres and stick there.

Other particles the same size as virus particles in floating water droplets are also trapped by the masks.

Dust particles from ground stone or fabric can be that small and they're trapped.

Broken fragments of pollen that size can get trapped by them.

Bacteria, mould and fungal spores.

Toxic smoke and smog particles.

Tiny ones.

FFP2+ and N95+ masks, fitted well, work for all of those.

Because of the simple physical properties of the universe...

... recorded and understood by scientists.
