Mask Replacement Filters

You should replace your mask or filters when breathing through the mask becomes more difficult, when the mask or filter is damaged, when the face piece becomes unhygienic, or when you can smell or taste solvents coming through the filters/mask. Respirator filters or masks with carbon have a maximum use time of approximately 6 months, since carbon can and will absorb contaminants from the environment even when you are not wearing the mask. As with all of our products, should you have any questions with a mask you purchased from us, contact customer service at 1-800-339-7123. We have replacement filters for the Respro Techno Mask, Respro Aero Mask, Honeycomb Mask, and 3M HEPA Masks.
