Humidifiers come in a wide variety of models and each one offers different features for different purposes. Knowing your needs is the first step to selecting the right model. Besides knowing the size of the unit to get and what type of humidifier filter it uses, there are other functions that are nice to have. Most are not crucial but some people like the added benefit of having the extra functions built into the humidifier.
The first thing to consider is the ease of use. How user friendly the humidifier is designed to be really matter especially when it is your first unit and the time comes around to replace the filter. It is nice to have a unit that can be easily taken apart for routine filter replacement and general cleaning. Also, it is nice to have a large water tank so that it requires refills much less frequently.
Noise is always a factor with many of these appliances and new models today are becoming much better at noise control. Most good brands are relatively quiet and that can be important for someone who is bothered by too much background noise, or intends on using the unit at night. Typically, warm mist units are quieter than cool mist humidifiers.
A humidifier with indicator lights to report when the water levels are low can really be useful. Some way of notifying the owner when the water tank is low on water is important because it can waste a lot of energy running on empty. More advanced units offer an auto shut off feature so the appliance turns itself off when the tank runs out of water.
Auto shut off can also apply to units that come with a humidity meter. With this feature, a user can set the desired humidity level and the unit will turn off when the target humidity is reached. Just as too little moisture can cause problems, over humidification can promote mold growth, dust mites, and mildew.
There are many other features that come with some humidifiers such as air purification and sterilization. However, all units use a humidifier filter which filters the air flowing through the unit. Remember the most important part of a humidifier is the humidifier replacement filter which needs to be changed regularly.
