This is a new design of respirator which has advantages for mass distribution, emergency preparedness, and multi-ethnic populations. I’ve been using/testing it for 5 or 6 years in the Unorganized Borough in Alaska.
The respirator can be cut with scissors to fit faces properly. Because they are clear, fit is easily ascertained. A clear respirator may mean they are more acceptable culturally (the face is not hidden).
The filters are replaceable. They allow a lot of air to pass through so can be useful in bike riding and outdoor work. They also allow moisture to pass through; I haven’t found the exhaled moisture to be a problem except in subzero temperatures (quite a bit of condensation then).
Instead of storing respirators of every size, only one size needs to be stored for emergency use. One doesn’t need to check sizes before distributing the respirators. Respirators can be cleaned and re-used by the individual (replace filters). I have seen them be used for pandemics, volcanoes, dust, woodworking, and cycling, and I am hoping to continue testing them in Alaska where we have faces from many different populations.
