Particulate filters remove solid particles from a liquid or a gas. The size of the particle’s removed depends on the grade of the filter, with filter grades running from .01 micron up to 200 micron. Particulate filters work from the outside in. The unclean liquid or gas flows into the filter, and then the clean liquid or gas emerges.
