What Are Whole-Home Humidifiers & How Do They Work?
A whole-home humidifier can be installed as part of your HVAC system. It works with your furnace in colder months to add moisture into dry air so your home environment feels more comfortable. Most people prefer an indoor humidity level of 35–55 percent and keeping your home in this range helps maintain wood furniture and floors.
What Are the Types of Whole-Home Humidifiers?
There are three types of whole-home humidifiers:
- Bypass humidifier—connects to the return section of your air handler or furnace. This relies on the furnace air blower to distribute moisture through the ducts into your home, and only operates when the furnace is running. This type of humidifier has very quiet operation and is ideal for smaller to medium sized homes.
- Fan-powered humidifier—has its own fan to distribute moisture through the ducts into your home. This type of humidifier puts more moisture into the air than a bypass humidifier and works even when the furnace is not running. This is ideal for medium to large homes.
- Steam humidifier—uses a heating element inside a canister filled with water to create steam, which is distributed to the air within your ductwork. This is ideal for large homes and/or arid climates.
