Humidifier Buying Checklist


There are a few features that are essential to a useful humidifier while others can be completely optional. It really depends on the reason you are looking for a humidifier but this is a simple checklist covering some of the basics which you can customize to your needs.

1. Humidity meter - A unit that allows the user to choose a desired humidity setting is very convenient to have since it can self-regulate. A humidifier with an auto shutoff feature when the target level is reached helps prevent over humidification. Over humidification can cause mold and mildew. The recommended relative humidity level is usually around 30% to 50%.

2. Low Water Indicator - Some humidifiers will have indicator lights to alert the user of changes in particular operating conditions. A low water indicator helps remind the user to refill the water tank as necessary. It is a waste of energy to run the unit on an empty tank. In the event that nobody is around to notice the indicator lights, some units offer auto shutoff when the water tank is empty.

3. Speed Settings and Noise Control - Most top brands today are very quiet but that might not be enough for some people who are disturbed by background noise, especially when trying to sleep at night. There isn't much you can do about a loud unit but if it offers speed settings, lowering the speed can reduce the amount of noise produced.

4. Unit Size - It makes no sense to buy a small table top unit if the purpose is to increase the humidity of a room the size of a concert hall. On the same note, there can be negative repercussions to operating a large unit in a small space. Determine whether you need a unit for the entire house or for just a room.

Those four items really cover the basics anyone would need to make an educated humidifier purchase. There are extra features offered by some models such as air purification, sterilization, or dehumidification but dedicated units for these functions will usually do a better job at their particular function. Nonetheless, some people enjoy the convenience of having these functions built in.
