Gas Mask Filters

Gas Mask Replacement Filters & Cartridges

NATO-compatible and proprietary filters for CBRN, NBC, and ABEK threats. Your protection is only as good as your filter — replace on schedule, store sealed, and never compromise on the rating for the threats you're preparing for.

Filter ratings explained

• CBRN: Chemical, Biological, Radiological, Nuclear — broadest protection
• NBC: Nuclear, Biological, Chemical — military standard
• P3: Particulate-only, including radioactive particulates
• ABEK: Organic vapors, acid gases, organic compounds

Shelf life and storage

Sealed filters typically have 10–20 year shelf lives in proper storage — but once opened, exposure begins immediately. Date-mark new filters when received, store in original sealed packaging in cool conditions, and rotate stock before expiration.

Pair with masks and full coverage

Filters work with mask bodies and full HAZMAT systems. See Gas Masks & Respirators for mask bodies, CBRN Gas Masks for highest-rated options, and HAZMAT Protection for full-body coverage.

Match the filter to the threat. Replace before you need it.
