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).
Prefilter Retainers (package of 2), Prefilters (package of 2), and Cartridges (package of 2) are each sold by the unit.
