    About Air Filter Efficiency Ratings
    industrial info icon

    Compare MERV rating, efficiency, and particle size to find the right filter for your location—from warehouses and offices to hospitals and labs.

    Low-Efficiency Reusable Air Filter Media

    Wash and reuse this media to extend the life of expensive filters that catch fine particles. Installed upstream, this affordable media traps debris that can damage or clog your final filter. Cut it to the size you need and attach it to a frame.
