Based on this comparison, it is reasonable to consider China KN95, AS/NZ P2, Korea 1st Class, and Japan DS FFRs as “equivalent” to US NIOSH N95 and European FFP2 respirators, for filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols (e.g. viruses). However, prior to selecting a respirator, users should consult their local respiratory protection regulations and requirements or check with their local public health authorities for selection guidance.

Steve Frye –
This mask is wonderful! I wear glasses on an constant daily bases, many times I have to take off my glasses in public as the mask and glasses put pressure on my ears. This mask is the first one that doesn’t create that pressure! It’s also very protective to the point I never had to fix my mask as often as I used to with other mask companies. I highly recommend this mask for anyone who constantly needs to fix their mask or has the glasses and mask pressure problem!

Very comfortable and a good fit. The neutral gray color is a plus. And the quick shipping is appreciated.
Nancy (verified owner) –
Great quality mask . I have this color and the pink ones as well. Very comfortable fit and they do not fog up my glasses.
Aron (verified owner) –
Very comfortable mask—I have probably a standard adult male sized head, and these fit maybe just a little loose. I have to do the inverted ear loop thingy to tighten them—even then it’s not SUPER snug.
My girlfriend has a slightly smaller adult female head, it’s very loose on her—too big.
Susan (verified owner) –
These masks are very comfortable with the soft ear loops. The style gives more space under the mask, so it’s easier to breathe. This is my husband’s favorite mask–and we have tried quite a few. We want to keep a stash on hand, as we like to be safe even as society is opening things back up.
