Air that is too dry can be uncomfortable to breathe, and can damage wood products like flooring, pianos, picture frames and cabinetry. 

In the winter, it’s especially important to add moisture to the air, since dry winter air can drive down the relative humidity level in your home to as low as 15%, which is drier than the air in most deserts. 

In-duct humidifiers

Whole House Humidifiers

If you have a forced-air heating system and want to humidify the whole house, consider an in duct humidifier. The unit will install on the air ducts and are plumbed to the water supply. Most are evaporative-bypass units, which blow air over a wet wick. Some emit a warm mist. Others are nebulizers, which use a spray technology and which may produce deposits of white dust from minerals in the water.

How It Works

There are basically two ways to increase moisture in the air inside your home. An evaporative humidifier uses a cool, fog-like mist and the other method is steam.

An Evaporative Humidifier is installed directly to your central heating and cooling system. Humidity is introduced into your home’s air in the form of water vapor. The resulting humidified air is then distributed via your heating and cooling system ductwork throughout your home.

Boiling water by a steam humidifier creates scaly deposits left on the water reservoir. To prevent the build-up of these scaly deposits, it is recommended that the water tank of the steam humidifier should be regularly cleaned and scrubbed free of mineral deposits. Water in any humidifier can get stagnant, if the units are not properly maintained and services.
