Humidifier FAQs

How do humidifiers put moisture into the air?
Humidifiers regulate humidity levels through evaporation. Humidifiers release their stored or flowing water into an air stream where the moisture is evaporated. Humidifiers mounted on the warmer side of a heating system will evaporate more water into the air than other units.

What’s the proper humidity level for my home?
It depends. Generally, the colder the weather outside, the more humidity you need inside. That’s because colder air tends to be drier air and, as the outside temperature drops, the moisture is drawn out of the house. To gauge the humidity level in your home, use an accurate hygrometer. Most people find that humidity levels between 30 and 40 percent are comfortable during the heating season.
What type of humidifier is best for my home?
Furnace-mounted humidifiers create moisture to increase humidity when the furnace blower is on. They are connected to a water supply and don’t need to be refilled. They also require very little maintenance. However, they use more water than the reservoir style. Reservoir-style units are also connected to a water supply, but because they store water they are more vulnerable to bacteria growth than flow-through units. However, bacteria growth can be curbed with an anti-bacterial treatment. If you need increased humidity in only one area of the house, we recommend that you supplement the humidity in that area using a free-standing portable or console style humidifier.
Should I leave my humidifier on all year long?
In cold climates, humidifiers are only necessary to increase humidity levels in the winter season. The humidity levels will increase as temperatures rise with the new season. At that time, the humidifier is no longer necessary. In warmer, dry climates it may be necessary to run a humidifier more frequently. You can use a hygrometer to monitor changes in humidity levels. At the end of the heating season, you may need to close the humidifier damper on furnace-mounted units until it is needed again. Check your owner’s manual for more information.
How do I know if my humidifier is working properly?
You can use a hygrometer to monitor changes in humidity levels. If the relative humidity is below 25 and it doesn’t increase over time you should check the humidifier to be sure it’s working properly.
