The purpose of a filter is to remove contaminants from a fluid stream either completely, or at least down to a given rating or specification. Filters are used to help control contaminants and are rated according to their ability to remove these contaminants from a liquid, gas or air stream. There are different methods in which the performance of filters are specified.
