The History of Aprilaire

A legacy of indoor air quality innovation


When investing in your family's comfort and health, you want to be sure you are getting the best solutions available. Aprilaire has a long history of helping families improve their comfort and health by controlling their indoor air quality.


Delivering comfortable, healthier indoor air has been our business at Research Products Corporation, Aprilaire's parent company, since its inception in 1938. That's when we first began to design, manufacture and distribute quality products that improve the indoor air of homes and businesses throughout North America.


Our reputation as an innovator in the industry was solidified in 1954 when we introduced the first truly effective whole-home humidifier. Since then, Aprilaire Humidifiers, have been imitated but never duplicated. We expanded the line and added an entire family of whole home indoor air quality products, including air purifiers (formerly sold under the Space-Gard® brand name), dehumidifiers, ventilation systems, thermostats and controllers, and zoned temperature control systems.


Our commitment to providing innovative indoor air quality solutions continues today and includes ongoing programs of testing, engineering, research, product refinement and practical experience. As a leader in the Heating, Ventilation and Air Conditioning (HVAC) accessories industry, we are able to work closely with associations such as the Air-Conditioning and Refrigeration Institute (ARI) and the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE).


These affiliations allow us to remain on top of industry standards and testing procedures. As a result, we're proud to offer a superior selection of indoor air quality products that help you stay healthy and comfortable and are conveniently sold and installed by local heating and air conditioning contractors throughout North America.
