Respirator Replacement Cartridges/pre-filters, 2-pk.

Long life prefilters features deep circular pleats which extend the amount of particulate loading on the filters, allowing respirator users to continue their spraying jobs or projects without the need to continually stop to replace the prefilter. Approved by NIOSH under the NIOSH 42 CFR 84 respirator certification regulations, approved to the R95/OV category, R95 filters are at least 95% efficient against oil-based contaminants and resist degradation for at least an 8 hrs shift. The OV classification means that the respirator is also approved for organic vapors. For use with 895.4570.
