Manufactured with high-quality activated carbon filtration media, the Dromex B1 Twin Unifit Filters efficiently absorb harmful inorganic gases and vapours while maintaining low breathing resistance for improved wearer comfort during extended periods of use.

For optimum performance, always inspect the filters before use and ensure they are securely attached to the respirator. Replace the filters immediately if breathing resistance increases, gas odours or tastes become noticeable, the filters become damaged, or according to your workplace respiratory protection programme. Store unused filters in their original sealed packaging in a cool, dry location away from direct sunlight, moisture, and chemical contamination.
Please note that the Dromex B1 Twin Unifit Filters provide protection against inorganic gases and vapours only. They do not protect against airborne particulates, organic vapours, ammonia, acid gases, or oxygen-deficient atmospheres. Where particulate hazards are present, use compatible particulate pre-filters, and always select the correct filter type for the specific workplace contaminants.
