Relative Humidity Chart

Your Home's Humidity Levels Matter

Humidity control in the house is important to maintaining Healthy Humidity. The effects of house humidity can have a major impact on the way you feel. The American Society of Heating Refrigeration, Air-Conditioning Engineers recommends keeping your home's relative humidity between 40–60%. While balanced humidity exists between 40 and 60%, it's important to remember that outdoor temperature and other home factors will impact what relative humidity level is attainable and recommended for your house. Talk with your AprilAire Healthy Air Professional to learn more.

Use our relative humidity charts to find the proper humidity level in your house.

Outside of this range, your air and your body are more susceptible to airborne pollutants such as allergens, mold, mildew, and viruses.
