There are different types of evaporative humidifiers for home usage, with some of these being used to humidify the whole home, while other smaller models are portable and can be best used for a single room only. However, no matter what size the unit is, they all work on the same principle when being used to humidify the surrounding air of a certain given environment. As the name suggests, an evaporative humidifier uses the principle of evaporation in its operation. Each one of these units has a small wick or belt inside that absorbs water, which is why they are sometimes referred to as wick humidifiers. A small fan then evaporates the collected water from this wick and propels the moisture into the air. These types of humidifiers, unlike other types, are actually self-regulating. In other words, once the surrounding air reaches a certain saturation point the evaporation will cease and no further moisture will be released into the air until the moisture level decreases and the evaporation begins again. Wicks or filters inside evaporative humidifiers for home use do need to be replaced every couple of months, or as often as recommended in the instructions you receive when you purchase the humidifier. There are some units that have reusable wicks and for those, all that is needed is to clean the wick regularly and place it back inside the humidifier. There are some important features that these types of humidifiers should have. In order for the unit and the surrounding air to remain bacteria free you should make sure that the humidifier you purchase has a filter inside that will trap impurities and neutralize bacteria. Some filters are replaceable and they should be changed as often as the instructions indicate. Other units have permanent filters that merely need to be cleaned and then placed back inside the unit. Other optional features you may want to consider include adjustable moisture settings, an automatic shut off, digital easy-to-read display, and a refill tank indicator. It is also a good idea to buy a model that is easy to clean and refill with water. Prices vary according to the size of the humidifier and the area it is rated to humidify. Usually the smaller, portable room units that are suitable for humidifying a bedroom, for example, cost anywhere from $30 to $70. The larger evaporative humidifiers for whole home use cost anywhere from $100 to $200 per unit.
