But it's keeping out... let's call it wood dust particles. A few orders of magnitude larger than a microorganism. Significantly larger than, say, oxygen. So such masks would allow you to breathe without a problem, while still protecting your lungs. And you only wear them while working on the saw, not all day. ....
