2. OK, they can capture particles even smaller than the coronavirus, but when you wear them, all the air just leaks in the side.

While discussing today about the faq entry on PM 10 versus PM 2.5 which I posted yesterday, my friend Klaus challenged on the usefulness of protection masks.

This is a good thing, since most of air pollutions bad health effects are caused by particles 2.5 microns and smaller (the width of a human hair is 70 microns). These masks really work.
