The maintenance-free 3M Half Mask 4279+ offers good respiratory protection as a user-friendly complete mask. The new and improved exhalation valve reduces breathing resistance during exhalation, decreases heat and moisture buildup, and thus facilitates breathing, especially in warm and humid work environments. The half masks in the 4000+ series feature a soft, skin-friendly, silicone-free facial seal. The filter class FFABE1P3 RD protects against many common organic gases, vapors, and particles in industrial settings. The lightweight, balanced design with integrated, maintenance-free filter elements ensures good all-around visibility. The integrated filter elements are maintenance-free. You can use the half mask until a replacement is required according to the filter change plan or the filters are saturated. Then, dispose of them professionally. The comfortable strap system with adjustable head support provides a reliable fit and adapts to different head shapes and sizes. The flat design does not restrict your field of vision, and the large switch buttons in an activated carbon filter ensure low breathing resistance. The filter class FFABEK1P3 RD protects against organic (boiling point above 65 °C) and inorganic gases and vapors, acidic gases, as well as ammonia and particles up to 30 times the limit value. A resealable bag for hygienic storage and transport is included.
