Wearing a dust mask or a respirator is one of the easiest ways to reduce or eliminate your exposure to dust, pollen, chemical pollutants, mold, bacteria, and other contaminants. 3M and Moldex dust masks carry a NIOSH approval rating (such as N95). For example, the 8233 N100 mask is the best high-rated respirator against lead, metal fumes, certain radioactive particulate materials, and non-oil containing mists. In general, all of these masks should be discarded after they become soiled, or breathing becomes difficult due to filter loading.
NIOSH Items: We only sell brand new respirators, filters, and dust masks from US based manufacturers. Since it can be difficult to determine if a respirator or mask has been used or even just tried on, for the protection of our customers, we do not accept NIOSH returns.
