The R95 particulate filtering facepiece respirator filters at least 95% of airborne particles and is somewhat resistant to oil.

This indicates the level of protection you can expect to receive from that respirator. Table 1 of the OSHA Respiratory Protection standard presents the APFs for each type of respirator. For more information about selecting the proper respirator for the hazard, please refer to the NIOSH respirator selection logic. Air-purifying respirators (APRs)

Because the effectiveness of this type of respirator relies upon the breathing air travelling through the filter, a tight seal to the user’s face is very important. Therefore, the Occupational Safety and Health Administration (OSHA) (29 CFR 1910.134) requires an annual respirator fit test to ensure that users receive the expected level

For example, if the commonly accepted APF for a half-mask respirator is 10 and the PEL is 5 mg/m 3, then 50 mg/m 3 is the highest workplace concentration in which a half-mask respirator can be used against that contaminant. If the workplace concentration is greater than 50 mg/m 3, a more protective respirator (with a higher APF) should be used ...

An N95 FFR is a type of disposable respirator where the filtration media is the respirator. The respirator forms a tight seal to the face and removes particles from the air that are breathed through it. These respirators filter out at least 95% of very small (0.3-micron) particles.

R95, R99, R100. Filters at least . 95%, 99%, or 99.97% of airborne particles. P. SERIES. STRONGLY RESISTANT TO OIL/OIL PROOF P95, P99, P100 Filters at least 95%, 99%, or 99.97% of airborne particles. OILS When products containing oil (like fuel, lubricating or hydraulic oils, solvents, paints, and pesticides) are sprayed or used in processes

Gaps can also occur if your N95 respirator is too big, too small, or it was not put on correctly. To check for gaps, gently place your hands on the N95 respirator, covering as much of it as possible, then breathe out. If you feel air leaking out from the edges of the N95 respirator, or if you are wearing glasses and they fog up, it is not snug.

A respirator labeled as a KN95 respirator is expected to conform to China’s GB2626 standard. NIOSH does not approve KN95 products or any other respiratory protective devices certified to international standards.

A quantitative fit test uses a fit testing instrument(s) to provide quantitative, or numerical, measurements of the amount of face seal leakage present when a user wears a respirator. Quantitative fit testing requires a hole punched in the respirator to perform the test. Therefore, the fit tester must dispose of the respirator after the test.
