Fresh, pure air became the top concern of Research Products Corporation over 60 years ago. That’s when we first began to design, develop, manufacture, and distribute quality products which improve the environment by conditioning the air in homes throughout North America.
We introduced Aprilaire® humidifiers in 1954 as the first evaporative, flow-through-design humidifiers. Since then, we've added the Aprilaire Automatic Humidifier, Aprilaire Steam Humidifier, Aprilaire High Efficiency Air Cleaner, Aprilaire Zone Control System, Aprilaire Electronic Thermostats and Aprilaire Energy Recovery Ventilator to continue our dedication to both quality manufacturing and more breathable, more healthful air. Our commitment includes ongoing programs of testing, engineering, research, product refinement, and practical experience. As a leader in the HVAC industry, we are able to work closely with industry associations like ARI and ASHRAE. These affiliations allow us to remain on top of industry standards and testing procedures. As a result, we’re proud to give you our assurances of superior quality and selection for indoor air products that help you stay comfortable. These products are conveniently sold by local heating and air conditioning contractors throughout North America.
DRI-STEEM® Humidifier Company, Eden Prairie, Minn., the industry's leading commercial and industrial humidifier manufacturer, is also a part of Research Products Corporation, the maker of Aprilaire® brand products for indoor air comfort in homes and light commercial applications.
