The Polygard 2000 P3 R is a high-efficiency particulate filter designed for respiratory protection. It is capable of filtering both oily and non-oily particulate contaminants, including dust, fumes, and fine solid or liquid particles. The filter has a P3 rating, which means it offers very high protection against particulates. It uses a bayonet connection that's compatible with many half-face and full-face respirator masks. In addition to particulate filtration, it helps reduce nuisance odors from organic vapors (to some extent), making it useful in environments where both dust and mild vapor exposure occur. It conforms to standards such as EN 143:2000 + A1:2006.
