Types Of  Whole House Humidifiers 

There are mainly three types of whole-house humidifiers that you can install; bypass, fan-powered, and steam.

Bypass Humidifiers: Bypass humidifiers add moisture to warm air through a furnace. These types of humidifiers take warm air from the home’s heating tubes and pass it via a water tray. This enables the air to collect moisture, which is then released back into the home. They are installed at return or supply end of your ductwork. Bypass humidifier doesn’t make as much noise because it isn’t equipped with the blower motor.

Fan Powered Humidifiers: The difference between bypass humidifiers and fan-powered humidifiers is that the last works with its own blower motor. They don’t need the aid of a running furnace to humidify your home. Fan-powered humidifiers don’t require a bypass duct. It can be installed in smaller spaces They are more energy-efficient, as the internal fan uses the same amount of power as a 25-watt light bulb. The bypass humidifier is perfect for a house built on slabs or with HVAC systems in a closet.

Steam Humidifiers: This type of humidifier opposes the other two because it doesn’t pass air via water panels to add moisture to it. Steam humidifiers work by electrically heating water to create humidity in the form of steam. Steam humidifiers are the most efficient and fastest way to increase and keep a good level of humidity in your home. Just like fan-powered humidifiers, steam doesn’t require the furnace to be running.
