Under the new particulate filter rules, there are three series of filters: N, R, and P. The N filters are Not resistant to oil; the R filters are resistant to oil; andthe P filters are oil proof.
The N series of filters is appropriate for airborne particles such as silica or lead, when there are no il-based products also in the air.
For example, an N series filter would be recommended during the removal of old lead paint. However, for spraying an oil-based lead paint, an R or P series filter would be recommended as rotection against the airborne mist of oil-based solvent.
The R series (resistant to oil) should only be used for a single shift when solvent or oil mist is present in the air. This filter resists oil but may break down in contact with oil or solvent over a long time.
When using P series filters, check the manufacturers instructions to determine how long the filter can be used when airborne particles are present. NIOSH originally thought that P series filters were oil-proof but recent tests have found there may be some breakdown of the filter material with long-term oil exposure.
Note: N, R, and P filters do not provide protection against organic vapors.
