Use in hot, humid, and dirty environments such as welding, soldering, brazing, grinding, sanding, sweeping, bagging, stone quarrying, metal machining, cement mixing, underground mining, polishing, buffing, lime, poultry, and textiles

The M2700 models also feature a Ventex® valve to let hot air out more quickly so workers stay cooler. In addition to the Ventex® valve, the M2800 models have an added carbon layer to filter out nuisance levels of ozone and organic vapors and flame retardants added to the shell to decrease flammability. These extra features make the M2800 models also useful in foundry operations, lab settings, agriculture, printing, food processing, paint and varnish manufacturing, chemical and waste processing, and sewage treatment.

All masks are NIOSH certified to have a filter efficiency of 95% or greater against non-oil based particulate aerosols. Masks are free of oil.

The M2600 models are constructed of black Dura-Mesh® to prevent collapsing and to look cleaner longer in order to get maximum use out of each mask. They are also lined with Softspun® for comfort and durability. Masks feature a contoured nose bridge with soft foam nose flange and an elastic HandyStrap® for all-day comfort. The HandyStrap® also features a buckle that allows the mask to hang around the neck when not in use.
