This respirator is approved by NIOSH under the NIOSH 42 CFR 84 respirator certification regulations. This Paint & Pesticide respirator is 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-hour shift. The OV classification means that the respirator is also approved for organic vapors.
These unique, long-life prefilters are designed by MSA for respirator users. Their exclusive Hawley® design features deep circular pleats which extend the amount of filter loading on the filters, allowing respirator users to continue their spraying jobs or projects without the need to continually stop to replace the prefilter. These prefilters are replacements for use with MSA’s 817666 Replacement Cartridges, which fit on all MSA Safety Works twin cartridge respirators.
