Ever wonder what N95 is referring to? How about R95 and P100? Well, you’re about to get a whole lot smarter!
As you know, all respirator filters and dust masks have a rating that consists of a letter and a number. The letters are N, R, and P refer to particulate respirators. Just so you know, particulate filters protect against airborne particles such as dust, mists, and liquids but do not protect against gasses and vapors.
N means the filter is not oil proof.
R means the filter is oil resistant up to 8 hours.
P means it is oil proof for over 8 hours.
The number is 95, 97, and 100 refer to the percent of particles it removes from the air.
Disposable respirators should be replaced after 8 hours of use or when soiled. After this period of time the mask is no longer effective and wearing one is basically useless. Not all dust masks provide a firm seal on your head and particles can still slip through the sides so make sure you tighten those straps to get the most secure fit to your face.
