3M 8835+ Premium Adjustable Strap Respirator (Valved) - FFP3. Provides respiratory protection against higher levels of fine dusts, mists, and metal fume. New filter construction and large surface area reduces breathing resistance making the 8835+ even easier to breathe through. The 3M Cool Flow valve effectively removes exhaled air, reducing heat and moisture build up. Soft, pliable face seal forms comfortably onto a wide variety of face shapes and sizes, helping give an improved fit. Adjustable red headbands indicate FFP3 protection level. Clever face seal design is engineered to help minimise fogging of eyewear. Industry proven 3M Cool Flow Valve directs humid exhaled air away from eyewear. Durable face seal can be wiped clean after use. Coupled with adjustable straps and an additional 'R' approval means 8835+ can be used for more than one shift. Standard: EN149:2001 + A1:2009 Classification: FFP3 R D. Maximum Use Concentration: 20 x WEL (Workplace exposure limit).
