All masks are not created equal, especially when you realize how small viral particles can be. So wondering what size virus your mask blocks may seem like overkill, but it's actually a very important question. The coronavirus is dangerous precisely because it is so small. And different masks are made to block different maladies.
For instance, masks made to block smog are designated PM 2.5. This means it blocks anything 2.5 microns in size and larger. To give you an example of size, a grain of beach sand is approximately 100 microns.
What do surgical masks filter out?
The coronavirus is about 0.5 microns in size if it’s on a water droplet. However, alone it can be as small as 0.1 micron alone.
If you want to know whether a mask is going to be safe, look for the word “surgical.” If it says surgical, the mask has undergone tests audited by the FDA that say that it can filter everything up to 0.03 microns.
Armbrust Masks are regulated by the FDA, which makes them effective in keeping out those dangerous, incredibly tiny COVID-19 germs away from your face.
