Is There an Ideal Humidity Level That Should Be Maintained in the Home?

Yes, there is an ideal humidity level that should be maintained in the home. It is generally accepted that relative humidity (RH) of 40-60 percent provides the most comfortable environment for humans and other living organisms. Too little humidity can cause problems such as dry skin, static electricity, and increased susceptibility to colds and allergies. On the other hand, excess humidity can create the perfect environment for dust mites and mold growth.

Colds and Allergies

Whole house humidifiers work by adding moisture to the dry indoor air. The most common type is the evaporative or “wicking” humidifier. This style of humidifier works by passing a stream of water over an absorbent pad and then blowing the resulting mist into an air duct. This humidifying method is more energy efficient than steam-style humidifiers and can be controlled with a simple humidity sensor.


In conclusion, whole-house humidifiers can be a great tool to help regulate the humidity levels in your home. They work by taking water from either a tank or directly from the water line and pushing it through a filter and into your air ducts. The moisture is then dispersed throughout your home, helping to maintain comfortable humidity levels year-round. 

When choosing a whole-house humidifier, it’s important to consider the size of the unit and its water capacity, as well as any warranties or service plans offered. With the right information and a bit of research, you can find a whole-house humidifier that meets your needs and provides a comfortable environment for your home.
