N95 and KN95 respirator masks are the same. Both masks are rated to capture 95% of tiny particles (0.3 micron particles, to be exact). Since N95 and KN95 masks are rated to capture 95% of 0.3 micron particles, people will often assume that masks can’t capture particles smaller than 0.3 microns.
The CDC reports that prolonged N95 mask use (including between patients) can be safe for up to 8 hours, and encourages each user to review each manufacturer’s recommendations prior to following this strategy. Current guidelines encourage wearing a face shield over the N95 to decrease the chances of soiling the mask.
Comes in a pack of 2 masks.
It is advised to place the mask in the microwave to seam clean for 3 minutes to disinfect every day.
