Humidity Levels in House Make Big Difference

Humidity control in the house is important to maintain healthy and fresh air. The effects of humidity can have a major impact on the way you feel. 

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

The American Society of Heating Refrigeration, Air Conditioning Engineers recommends keeping your home between 40-60 percent. This is the optimal level of health and comfort. 

Outside of these levels, your air and your body are more susceptible to airborne viruses, allergens, mold, and mildew.
