Keep Your Respirator Working Safely

Parts for the respirator will wear after normal use and can be replaced individually—without replacing the entire system. Both prefilters and cartridges should be replaced after 30–60 days of use for the safest operation. All are approved for safe use by the National Institute for Occupational Safety and Health (NIOSH).

Retainers, Prefilters, and Cartridges, when ordered alone, will typically ship in a small box. Where possible, we will combine ordered items to reduce the number of boxes shipped.
