Size of the area to be humidified, maintenance levels and special features of the unit are some of the major factors to consider when determining which furnace humidifier to buy. A furnace humidifier creates a healthier indoor environment by adding moisture to the air moving through the duct system.
When choosing a furnace humidifier, first consider the size of the space where it will be installed. The efficiency of a furnace humidifier largely depends on the size of the room it is installed in. Most whole-house humidifiers have an output range of 9+ gallons of water supply per day. This makes them ideal for humidifying many rooms at a time.
Look for a model that is easy to maintain. Most whole-house humidifiers are connected directly to the main water supply of the house; hence, there is no tank to refill or maintain. Depending on the humidifier chosen, it can be cleaned with water or vinegar to reduce limescale buildup. Some furnace humidifiers also have components that need to be replaced periodically.
Check for special features, such as a timer or an automatic humidistat, that allow the humidity level to be controlled. Some models also have an automatic shut-off feature that turns off the unit when the water level reduces. These features help to make the unit more energy efficient.
