Toxic Dust Respirator Replacement Cartridges P100, 2-Pk.

Keep yourself safe from harmful dusts and debris with the Safety Works 2-Pack Toxic Dust Respirator Replacement Cartridges P100. These cartridges are compatible with the Safety Works Toxic Dust Respirator and are approved by NIOSH under the NIOSH 42 CFR 84 Respirator Certification Regulations for the P100 filter classification. P100 filters offer the highest level of dust protection available in a NIOSH approved cartridge. The cartridges feature an air flow opening positioned at the back of the cartridges so that the dust and debris is less likely to clog the filters. The opening also facilitates blocking the cartridges with thumb for an easy fit check when on the respirator.
