PERRIN foam filters are made of reticulated polyurethane foam which offers a minimal amount of air. The filter element is sprayed with a special oil that adheres to the foam making the poly matrix sticky and retain dirt. Foam filters do not block dirt, they grab it! All while making minimal drops in air flow as they grab dirt! What does this mean to you? More dirt collected, more air flow and no clogs!
