About Aprilaire

Fresh, clean air became the top concern of Research Products Corporation over 60 years ago. That's when we first began to design, manufacture and distribute quality comfort products which improve the indoor air of homes and businesses throughout North America.

In 1954 Research Products Corporation introduced Aprilaire® humidifiers, the first evaporative, flow-through-design humidifiers. Since then we've added on to our line of Aprilaire humidifiers as well as added an entire family of indoor quality products that include Aprilaire air cleaners (formerly sold under the Space-Gard® brand name), dehumidifiers, thermostats, ventilation and zone control systems to continue our dedication to both quality manufacturing and more comfortable, healthy indoor environments. Our commitment 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 industry 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.
