Best Room Humidifier for Small Rooms in 2017

best room humidifier

Besides the option of having a whole house humidifier, you may like to consider having one in the room. In this post, we will guide you along on how to find the best room humidifier in 2017.

So you may ask why do we need a room humidifier? In our earlier post, we discussed about several benefits of having a whole house humidifier. Similarly, the benefits of having an ideal temperature and humidity in a well-controlled environment applies here.

Ideally, one should not feel too warm or too dry in the rooms. In winter, it is very helpful towards a better night’s sleep when the room is cooler and moisture in the air is kept in check. The cold and dry climate during winter may also affect the nasal passages, thus it is a good idea to have humidity levels regulated in the room for a good night’s rest.

Types of Small Room Humidifiers

There are essentially two types of room humidifiers:

Cool-Mist Humidifiers

  • May come with ultrasonic or evaporative technology to generate the mist
  • Does not use heated water
  • Consumes little electricity
  • Ultrasonic humidifiers are generally quieter than warm-mist humidifiers; however evaporative units are noisier due to operation of the fan
  • Children and pet friendly due to the lack of a heating element. Ideal for areas within their reach and cause burn injury
  • Mild cooling effect in the ambient air
  • Must be cleaned regularly before each water refill to prevent bacterial growth
  • Wick filters should be replaced about every 2 months

Warm-Mist Humidifiers

  • Water is heated with a built-in heating element and boiled to turn it into steam
  • Water is sterilized by the heating before being pushed out into the air
  • Low running costs
  • No need for replacement filters unlike cool-mist humidifiers
  • Most units automatically shut off when the water tank dries up
  • Safety hazard at home due to potential burn injuries from hot water spillage
  • Higher tendency to build up mineral deposits during the boiling process
  • Warm air produced may be more comfortable during winter

There may be some differences in how cool-mist humidifiers and warm-mist humidifiers function, but both types work well to humidify the air in the rooms.

While we may be recommending humidifiers for winter, they can be used throughout the year. It will be good to maintain a humidity level of about 30-50% at all times of the year so that we can avoid any dry skin or nasal congestion, and eventually enjoy a good night's sleep. This is also applicable in air-conditioned spaces experiencing humid weather outdoors. 

The choice of water is also important in the long term use of humidifiers. The hard water from the faucet may leave you with more mineral buildup in the unit. This will require you to do more thorough cleaning and it may also leave a faint white dust around your house. It may be a wise choice to opt for distilled water instead to minimize the trouble of cleaning up the humidifier and the house and maximise the humidifier's efficiency. 

Features of Small Room Humidifiers to Consider

There are several factors to consider when it comes to choosing the best room humidifier for your house. Let's take a look at them:

Low Noise​

A quieter unit will ensure that your sleep does not get disturbed by the buzzing or sound of water boiling.


It will be good to have one that is built in so that you can adjust the relative humidity and maintain it at your preferred levels constantly.

Automatic Shut Down

Most units come with this safety feature these days to prevent any fire hazards that may occur from boiling without water in the tank.

Cleaning and Maintenance​

Water tanks that are removable will make cleaning and refilling a breeze.

Antibacterial Features

Some units have different ways of keeping the bacteria growth in the water tanks in check and include filters, cartridges and UV light.

The cartridge can be replaced once the lime and mineral builds up.
