The 3M™ Particulate Filter 2138 gives P3 R protection against solid and liquid particles and ozone up to 10 x OEL, with additional protection against organic vapours and acid gases below OEL.
The filters are small and lightweight, with low breathing resistance and good balance on the mask, and fit comfortably under welding shields. They click into place with the 3M bayonet filter attachment system and suit any half or full face 3M reusable mask with a bayonet-style connection.
