R95 and P95 particulate respirators made by 3M were designed for every profession in mind. There is no need to breath in those harmful particles. R95 and P95 respirators filter the unwanted particles and gases that float in the air. No matter what the application; painting, welding, asbestos, or woodworking, these particulate respirators will keep you safe.
Respirator Classification
The nine classes of filters defined by OSHA is broken down into three series; N, R and P. All three series have efficiency levels of 95%, 99% and 99.97%.
R Series - are resistant to oil, which means it will filter out any particle including oil based liquid aerosol. They may be used for any solid or liquid airborne particulate hazards. This respirator should only be used for no more than 8 continuous hours. Extended use is possible if workplace setting doesn't degrade the efficiency of the respirator. R95 respirators have at least a 95% efficiency level.
P Series - P95 respirators should be selected if there are oil aerosols. They may be used for any solid or liquid particulate airborne hazard. This respirator can be used and reused based on damage, user hygiene and increased breathing resistance. NIOSH recommends disposal of the P95 respirator after 40 hours or 30 days of use, whichever comes first. The P95 respirator has at least a 95% efficiency level.
