General Filters

Founded in 1937 in Detroit, MI by Art and Grace Redner, General Filters, Inc. began manufacturing oil filters out of their small home in Detroit.

During World War II, General Filters did its part to help Detroit become the “Arsenal of Democracy”.  The company designed and built a portable filtration system for the Allied fighter planes and bombers operating in the difficult environment of North Africa.  The filter was mounted on the back of a jeep and could be driven to each plane to filter the oil; significantly reducing service time and increasing the number of missions each plane could fly on a daily basis.

This experience changed the focus of General Filters from a service company to a true manufacturing company. General Filters, Inc. moved into the Indoor Air Quality (IAQ) Market by manufacturing and marketing GeneralAire® whole-house humidifiers in the early 1950’s.

Today, General Filters is striving to become the industry leader of indoor air quality and filtration products by improving the quality of our customers’ lives with outstanding products and services. We plan to achieve this by utilizing industry experts and leading edge technology to develop products with exceptional quality and performance. These products will be competitively priced and marketed globally through distribution channels that value customer relationships and remarkable customer service.
