From demolition to woodworking, some environments have a high risk of exposure airborne particles that can wreak havoc on your respiratory system. These NIOSH certified masks filter at least 95% of non-oil-based particulates in the air, while the adjustable nose bridge and foam lining create a secure comfortable seal, allowing you to work safer for a longer period of time.
