A Brief History

Omnipure Filter Co. was established in 1970 after William Reid an engineer, designed and built the world’s first disposable inline water filter. Mr. Reid developed the simple carbon filter to function efficiently, and be reproduced with precision. Simple and effective, the CL series found widespread applications behind commercial ice machines, water coolers, and coffee machines. The CL series continues as one of many Omnipure series of filters in use today. In time, William Reid handed over the reins of the company to his son, Roger Reid, also a trained engineer. Roger soon developed several cutting-edge filter body designs that revolutionized the industry. Sound engineering and manufacturing techniques drove the popularity of Omnipure’s filters and led to a world-wide reputation of distinction. Omnipure manufactures all of its filters in Caldwell, Idaho USA and continues to expand offerings around the globe. The company has grown and continues its commitment to service, and quality of the best inline water filters in the world.
