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.

In 2010, Koch Filter Corporation was acquired by Tomkins plc.  Ownership has changed but Koch’s experienced management team remains.  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 Tomkins family of companies.  Same experienced management team; same quality products; same friendly and knowledgeable Customer Service representatives; same reliable sales force…even the same voices answering the phones when you call!  And, as we have since our founding, we continue to pride ourselves on our ability to be flexible and make decisions based on our Customers needs.
