Aprilaire entered the indoor air quality industry in 1938. Less than two decades later, they produced the first marketed, whole-home, evaporative humidifier in the United States. Since that time, they have expanded their product line to include not only humidifiers, but also air cleaners, dehumidifiers, thermostats, ventilation and zone control systems.

The company's focus has always been to design, create and manufacture top level products to help improve indoor air quality. Commitment to discovering new, innovative ways to establish healthy indoor environments, whether in homes or businesses has contributed to Aprilaire remaining a leader in the HVAC industry.

When it is time to replace the filters on your Aprilaire products, such as humidifiers and air cleaners, make sure you choose genuine Aprilaire replacement filters and parts.
