Furnace humidifier basic !

Furnace humidifiers are the best way to control the relative humidity of all the air in a house. They are installed as part of the ventilation duct work near a furnace, and provide humidity whenever a furnace is running. Generally speaking, furnace humidifiers are fitted when a heating system is installed, since they are designed to be fully integrated into it.

All furnace humidifiers apply the same basic principles to humidify hot air, but they come in two basic types. The first type is a flow-through design, where water flows into a humidifier and then drains out. These are commonly mounted on the air return duct on the furnace and connected to its hot air supply. Inside the humidifier, warm air absorbs moisture from an evaporator pad, and from there goes into the furnace to be dispersed throughout the house.

Furnace humidifiers also come in a second variety, namely the reservoir humidifier. In this type, there is a reservoir of water and a rotating drum to introduce moisture into the air. One risk associated with these humidifiers is that in some cases, bacteria and mold can grow in the reservoir’s standing water. Microorganisms like these can lead to humidifier fever, an inflammation of the lungs. However, proper care and cleaning of the reservoir can reduce or eliminate this risk.
