Why are humidifiers only used for heating?
In the winter when cold outdoor air enters a home it tends to dry out as it warms up, which increases the static electricity in the home and causes sinus problems. Adding a humidifier helps to add moisture back into the air and limit sinus problems. In the summer, even with outdoor relative humidity hovering around the single digits, the humidity in your home tends to be around 40%. The average comfort range for relative humidity in a home is from 35 to 45%.
