Uni Filter is an American manufacturer specializing in high-performance foam air filters designed for motorcycles, ATVs, UTVs, and off-road vehicles operating in harsh, dusty environments. Founded in 1969, Uni Filter pioneered reusable open-cell polyurethane foam filtration that delivers excellent airflow while trapping dirt and debris more effectively than traditional paper filters when properly oiled.

This collection includes Uni Filter two-stage foam air filters, pod and universal filters, replacement elements, foam sheets, and service kits. Uni’s dual-layer foam designs capture large and fine particles without sacrificing airflow, helping protect engines during aggressive riding and competition use. Made in the USA and trusted across motorsports, Uni Filter products are ideal for riders and builders who want reusable performance, strong filtration, and long service life for off-road and powersports applications.
