3M 4251+ FFA1P2D Valved Reusable Half Mask

The 3M 4251+ half mask is maintenance-free and ideal for most workshop applications including protection from paint fumes and dust. This mask has an integrated cartridge, set of filters and an enhanced valve assembly which assists the user to reduce exhalation breathing resistance. The close-fitting textured face seal is soft, silicone-free and non-allergenic which benefits the user to wear for long periods of time. The P2 R D filtration protects you from a combination of particulate hazards plus organic vapours and gases.
This lightweight design is ideal for use in hot and humid conditions due to its central positioning of the exhalation valve which helps reduce the build-up of heat and moisture. The resealable bag provided is designed for the mask to be stored in whilst not in use which will allow up to 40 hours of use life if stored correctly.
