The same principle works for warmer living spaces where there’s a need to reduce on the ambient temperature.

Warm mist and ultrasonic units can make some noise when the water boils, but these sounds are not distracting.

You can calculate the room area by multiplying its length and width (for-example: 6 x 7 meters = 42m2). To get the room volume, multiply the room area by the ceiling height (42 m2 x 3.5 meters = 147 m3).

*Find out about the water tank-size of a humidifier: The size of the water-reservoir will determine the frequency of filling. Most humidifiers have a 2-to-3 day capacity when functioning in the lowest setting while some models last for a few hours. Also consider a humidifier with an easy-to-clean, removable & refillable tank.

*Get to know about the cleaning procedure: Do your research and check if there are complaints about cleaning your humidifier. Ease of cleaning is very important when choosing a humidifier.

*Decide on how much your willing to spend on a humidifier: Average models come with a $30-to-$300 price range. So, if your looking for a small model to humidify a specific area in your house, then you should go for a lower budget. If your looking for a whole-house, then you should consider spending more but its actually worth it in the long run.

*Decide on particular features you want from a humidifier: most home humidifiers come with smart features which may include; Auto shut-down, Humidistat, Oil-diffuser, Water reservoir indicator, Filter-indicator and a lot more.
