About Us

Our History

Aprilaire is a division of Research Products Corporation of Madison, Wisconsin.

Fresh, clean air has been the concern of Aprilaire since its inception in 1938. That’s when we first began to design, manufacture, and distribute quality comfort products that improve the indoor air of homes throughout North America.

In 1954, we introduced the first evaporative, flow-through humidifiers. Since then we’ve added to our line of humidifiers as well as an entire family of indoor quality products including air purifiers (formerly sold under the Space-Gard® brand name), Dehumidifiers, Thermostats, Ventilation, and Zoned Comfort Control systems.

In 2001, Research Products acquired DRI-STEEM, leaders in humidification products for the commercial market segment. The DRISTEEM and Aprilaire association has provided powerful synergies in product design and manufacturing techniques that have resulted in the introduction of humidification products that fill more applications than ever before.  

Mission and Vision

Our mission is to provide our customers with exceptional service and superior products that condition or control the air for HVAC applications.

Our vision is to be the indoor comfort partner of choice of the HVAC contractor and distributor.

Core Values

We strive to focus on values that build and maintain a strong, vibrant workplace; one that fosters an environment of top-notch quality and service. Our values focus on innovation, achievement, knowing our customer, passion, fun, and being good neighbors.

Aprilaire continually gives back to the community. Through our employees’ efforts each year, we assist organizations like Habitat for Humanity, local food banks, blood drives, annual scholarship funds and the United Way.

Go to Market Strategy

Aprilaire is dedicated to the HVAC distributor and contractor channel. We work with a strong representation of distributors and we do not sell directly to retail. Our dedication to the channel is further illustrated with our regular participation in industry organizations and events.

As a leader in the HVAC industry, we 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 superior air quality solutions that help homeowners stay healthy and comfortable and help our partnering distributors and contractors’ businesses grow and prosper.


Our Quality Promise

Through continuous improvement, Aprilaire provides high quality products and services that exceed our customers’ expectations. The Aprilaire quality system meets ISO 9001:2008 requirements.

The quality management system ensures we develop, provide, maintain and continually improve products and services that meet and exceed customer expectations.

The requirements of the Aprilaire quality management system are defined by:

  1. Processes are identified that are needed for the quality management system and their applications throughout the corporation.

  2. Criteria and methods are determined as needed to ensure that the operation and control of all processes are effective.

  3. Resources and information are made available to support the operation and monitoring of these processes.

  4. Processes are monitored, measured and analyzed.

  5. Actions are implemented as necessary to achieve planned results and continual improvement

  6. When any process that affects product conformity is chosen to be outsourced, controls are maintained over those processes.

Aprilaire ensured that all requirements received from the customer are fully understood and that current capability exists to meet all aspects of the customer requirements prior to the acceptance of the order.
