Our respirator has a textured face seal that s soft, non-allergenic and silicone free, and provides FFABE1P3 R D protection against a range of organic and inorganic vapours, acid gases, and combination particulate hazards.

The integrated cartridge and filters are maintenance free; simply use until your change-out schedule indicates a replacement is needed or when the filters are full, and then discard. An adjustable head cradle helps fit to a broad range of head shapes and sizes, and the neck straps are easy to fasten. The low-profile design won t hinder your peripheral vision, and the two large, bonded-carbon filters provide low breathing resistance.
