A whole house humidifier is a great tool to help improve your indoor air quality so you can feel more comfortable in your home year round. Too little humidity and you can experience the symptoms above. Too much humidity can create problems like mold production in your home. 

 

Many people don’t think much about a humidifier in their home, even when they are experiencing health or other symptoms (static electricity, warped woodwork, etc). Making sure your humidifier is working properly and your settings are correct for the time of year and where you live is often overlooked, but very important to the overall air quality in your home.  

Three Things to Understand About Relative Humidity:

Relative Humidity 

The amount of water vapor in the air inside your home. 


How Humidity is Measured

Measured in percents and indicates the percent of humidity in the air compared to the amount it can hold before the water is forced to condense. 


Humidity Changes by Season 

Relative humidity changes with the temperature of the air. Warmer air can hold more water than cooler air. Because the cooler outdoor air in humidity levels drop with a drop in outdoor temperature. 

What Should My Furnace Humidifier

Be Set At In the Winter 

Your humidifier that’s attached to your furnace or HVAC system is set based on relative humidity. A comfortable relative humidity for most homes throughout the summer, spring, and fall is between 30 percent and 50 percent. If you set your humidifier to this level, it should be comfortable for your home and family most of the year.

 

However, when temperatures drop significantly in winter, you may need to re-adjust this. A humidity level around 50 percent will cause damaging condensation on your home’s window sills and walls. When the temperature is between 0 and 10 degrees, you will be better served with a humidity level of 20 percent. At between 10 and 20 degrees outdoor temperature, change the setting to 25 percent.
