Aprilaire has been a brand leader in humidification control for more than 75 years. We strive to help our customers not only improve the relative humidity in the house, but also understand.

The relative humidity charts below help you understand how humidity impacts your health, comfort and home. As you can see from the other relative humidity charts, indoor air quality can change how cold or hot we feel and the level of contaminants in the home. The best way to control indoor relative humidity is with a whole-home humidifier and dehumidifier.
