Filtering Facepiece
Mechanical filters are a class of filter for air-purifying respirators that mechanically stops particulates from reaching the wearer's nose and mouth. They come in multiple physical forms.

Since the filters cannot be cleaned and reused and have a limited lifespan, cost and disposability are key factors. Single-use, disposable and replaceable-cartridge models exist. Mechanical filters remove contaminants from air in the following ways: # by ''interception'' when particles following a line of flow in the airstream come within one radius of a fiber and adhere to it; # by ''impaction'', when larger particles unable to follow the curving contours of the ai ...
