Indoor Humidity

What is the proper humidity level?

The optimum range for indoor humidity is between 30-40% humidity. If you go above this level, condensation can occur and lead to allergy and respiratory problems. Dust mites thrive at around 50% and humidity over 60% leads to a variety of asthma, allergies and respiratory infections. 

How humid should my home be?

While too much humidity is bad, too little humidity can also be a problem and lead to dry nose and throat, dry skin and static electricity.
