Masks and respirators equipped with A2P3 Filters combine protection from particulates, dusts, mists and organic vapours. P3 is the highest level of particulate filtration available, filtering 99.5% of particulate contaminants in the air. A2 protects from the same vapours as A1, but can filter higher concentrations of the contaminates. This makes A2P3 filters suitable for a variety of industries, such as construction, mechanical work, agriculture and more.
