Even during DIY projects, toxic fumes and particles are often present that can irritate and harm our respiratory system. Whether handling pesticides, stripping paint, working with insulation, or repairing ceilings with gypsum dust: the 3M half mask reliably protects you against chemical vapors such as ammonia and sulfur dioxide, as well as solid and liquid particles. Despite its high level of protection, the half mask has several features that make it more comfortable to use. It offers unrestricted visibility, is relatively lightweight for a mask of this protection level, and has integrated filter elements with very low breathing resistance. A parabolic exhalation valve ensures that it doesn't get too warm under the mask.
