Founded in 1966 by Joseph Koch, Koch Filter Corporation is a world-class manufacturer of air filtration products. Koch Filter is recognized worldwide for its leading brand of high efficiency air filtration products and wider range of air filters for any industry demand.

Our wide range of filtration products is currently installed in more than 50,000 commercial, medical and industrial accounts worldwide.

Koch Filter Corporation maintains an ongoing Quality Assurance Program (QAP) to ensure total customer satisfaction with every filter we ship.

By focusing on providing total customer satisfaction, Koch's QAP is able to cover the entire manufacturing process. Starting with excellence in engineering standards, manufacturing begins with the proximity inspection of raw materials by experienced people.

From this initial rigid review of component materials through all phases of production to the final inspection of the packaging, the QAP matches the integrity and standards of all Koch employees. As a last step in the quality assurance program, internal inspections are regularly audited by independent testing laboratories. These independent tests are conducted in accordance with all current ASHRAE standards.

Today Koch Filter utilizes its North American footprint manufacturing (4 locations), our authorized distribution network (300 locations) and over 30 highly qualified sales engineers, experienced customer service professionals and production staff trained to LEED, Kaizan, ISO, NESHAP, SPC and SIX SIGMA's activities to provide quality products to a diverse clientele.
