Thousands of thin strands of fibers are melted together into a layer of web-like filter particles to trap microbes and particulates. Most respirator masks are made of polypropylene, which is a synthetic plastic that also gets used in clothing like rain jackets and yoga pants. If your job site contains a combination of these hazards, a combination filter and cartridge are necessary. Where filters provide protection from many dusts, fibers, fumes, or mists, cartridges protect against different gases and vapors. Respirator cartridges are a somewhat different form of protection. Understanding respirator filter ratings will help you to select the appropriate PPE for your job. ![]() P filters are oil-proofed, explicitly providing protection against oil-based (like lubricants, cutting fluids, glycerin, pesticides, and solvents) as well as non-oil-based particles, mold, and asbestos. R filters are oil resistant for occasional oil exposure but will lose effectiveness over time and need to be replaced after 8 hours. N filters are not oil resistant, but they will protect against dust, mists, and fumes that don’t have oil aerosols. The number (which can be 95, 99, or 100) represents the percentage of airborne particles-most of which you can’t see with the naked eye-that the mask is able to remove from contaminated air (although 100-rated masks will filter at least 99.7 percent of particles). Respirator filters will have ratings that consist of a letter followed by two or three numbers. Respirators come in disposable half-face styles (with and without valves) and reusable styles, and the filters and respirators themselves are rated by NIOSH based on the types of protection they provide and optimal operating conditions. What is the difference in respirator filters?Īll true respirator masks are designed to protect your face from airborne particles and liquids. Since it can be difficult to determine if a respirator or mask has been used or even just tried on, for the protection of our customers, we do not accept NIOSH returns. NIOSH Items: We only sell brand new respirators, filters, and dust masks from US-based manufacturers. Check out the full line of reliable 3M respirator products that we offer.
