HandyStrap allows mask to conveniently hang down around the user’s neck so it’s always ready for use and helps prevent premature disposal. Exclusive Dura-Mesh® shell protects the filter media so it stays cleaner-looking longer. Shell resists collapsing, even in heat and humidity. Contour-molded nosebridge with soft foam nose cushion provides an easy, comfortable fit. There’s no metal to adjust and the seal is maintained without pressure points. Softspun® lining gives added comfort and durability. The 2700N95 Series features the HandyStrap and Ventex® valve which lets the hot air out faster, so workers breathe easier and stay cooler longer. The 2800N95 Series features the HandyStrap and has an added carbon layer that helps filter out nuisance levels of ozone and organic vapors (less than OSHA PEL). Fits easily under welding hoods and is suitable for most welding applications. NIOSH certified to have a filter efficiency level of 95% or greater against particulates free of oil.
