The PD-100 full face gas mask respirator by Parcil distribution comes with proprietary threaded P-A-1 filters that are designed for better visibility than traditional filter models. Each filter cartridge is a dual-purpose organic vapor and particulate filter, classified as a "Non-Powered Air-Purifying Particulate Respirator with Combination Gas/Vapor and Particulate Filtering Cartridges. Activated charcoal is used to filter out organic vapors and the KN95 particulate filter is used to filter harmful microscopic particles. Our KN95 filters are ASTM tested to meet the same specifications as N95 ratings as per NIOSH regulations. Our filters can be used against many common chemicals found in cleaning compounds, alcohol, asphalt, mold, coal, detergents, disinfectants, fumes, hospital odors, industrial wastes, organic chemicals, poison gases, resins, viruses, and many others. Chemicals filtered: dust, gasoline, smoke, carbon dioxide, ether, nitroalkane, nitrobenzene, carbon trichloride, nitrobenzene, chlorine benzene, acetone, anilines, carbon dioxide, carbon tetrachloride, chloroform, chloropicrin, and many other pollutants. Useful applications include mold remediation, chemical production, fire inspection, epoxy resin, mining, metallurgy, herbicides, pesticides, industrial production, paint application and smoke/toxic vapor. Each mask comes with two P-A-1 filters, 1 user manual, an ASTM test report and replacement clasps. Color: Navy Blue & Black.
