About Koch Filter

Visit the Koch Filter Website -

Koch Filter Corporation was founded in 1966 by Joseph M. Koch. From humble beginnings in a two-room office in Louisville, Kentucky, Koch Filter has evolved into a world-class manufacturer of air filtration products.

Koch is recognized globally for its premier brand of high efficiency air filtration products and the industry's broadest range of air filters for any application. Our wide array of filtration products is currently installed in over 50,000 commercial, medical and industrial accounts worldwide.

Nearly a half-century after our founding, the company continues to grow with second-generation family leadership. Koch Filter is a stand-alone entity within the Air Distribution Technologies, Inc. family of companies. In place today are the same experienced management team; the same quality products; the same friendly and knowledgeable Customer Service representatives; the same reliable sales force, and even the same voices answering the phones when you call! As in the past and moving forward, we continue to pride ourselves on our ability to be flexible and make decisions based on our Customers' needs.

Within Air Distribution Technologies, Inc., Koch Filter is the first component of an exciting new Filtration Division. By leveraging their world-class manufacturing and engineering capabilities, this enables us to increase our product offering, adopt best-in-class manufacturing practices, and introduce new products at a faster pace, which translates into greater potential sales for our distributors.

Koch Filter's Corporate Headquarters and primary manufacturing plant are located in Louisville, Kentucky with other manufacturing facilities in Houston, TX, Rancho Cucamonga, CA, and East Greenville, PA. Plans are already underway to open additional manufacturing locations in coming years.
