Buying guide: Humidifiers

Types of humidifier

There are various models and sizes of humidifiers, including portable and whole-home models. As the name suggests, portable humidifiers are more versatile, and you can set up these small, powerful devices in any space of your home. On the other hand, whole-home humidifiers are purely suitable for staying fixed in one spot.

Most humidifiers are simple to operate, simply requiring water in their tank accompanied by a power source. They add humidity to the air differently depending on the type of humidifier you purchase.

These are the six main types of humidifiers:

  • Cool mist: Add moisture to the room without increasing its temperature (suitable for warm climates)

  • Warm mist: Add moisture to the air and increase the temperature of the room (suitable for cold climates)

  • Dual mist: Emit either cool or warm mist

  • Ultrasonic: Use vibrating metallic diaphragms to create cool or warm mist, quietly and with minimal energy consumption

  • Evaporative: Use a fan to circulate humidity through a moisture wick filter; easy to maintain, but only produce cool mist

  • Vaporizers: Alternates between cool and warm mists, but consumes more energy and can become extremely warm while operating

Size of the space to humidify

Before buying a humidifier, it’s helpful to measure the size of the area you are trying to humidify.

For small-to-medium-sized spaces

If you want to add moisture to your home office or bedroom, a room or tabletop humidifier offers these benefits:

  • Compact: Designed to be placed on a counter, desk, dresser or other tables

  • Easy to move: Lightweight for convenient portability

  • Long-running: Can typically operate for about 24 hours

  • Added features: May have several additional features, such as both cool and warm mists, easy-to-use interface, built-in hygrometers and low water indicators

For multiple rooms

People sometimes want to increase moisture in their entire home, so a whole-house or console humidifier is the most suitable option based on the following features:

  • More powerful humidification: Can deliver more moisture than compact humidifiers

  • Large humidification area: Can humidify areas as large as 3,000 square feet

  • Stylish: Available in variable finishes and designs to blend in with your décor

For significant humidification issues

If you have a severe humidification issue at your home or office, the most suitable option will be a ducted/HVAC humidifier. Once installed with the water line, these devices work alongside the central air system to constantly disperse moisture into the indoor atmosphere. These humidifiers do not require refilling because they draw water directly from the water supply.

Are humidifiers loud?

Buyers are frequently worried that a humidifier will make too much noise. You can expect every humidifier to make a bit of noise, but certainly some devices tend to make more noise than others. As a result, you will need to look for a quiet humidifier if you intend to use one in bedrooms, nurseries, and offices.

Ultrasonic humidifiers are usually the quietest type because they use special high-frequency sound waves, which are higher than our ears can detect, to produce mist.

Maintenance required for humidifiers

Normally, humidifiers are low-maintenance devices, but regular cleaning of the water tank will ensure that the device does not grow bacteria, mildew, and mold. This will help extend the longevity of your humidifier and prevent exposure to harmful pollutants. (Please note that some cool mist humidifiers have an internal wick filter, so cleaning it will not help; instead, you will have to replace it periodically.)

You should also regularly check the misting outlets to confirm that moisture flows smoothly through them.

Important considerations before buying a humidifier

These are some factors worth considering before you purchase a humidifier.

Convenience of use

Some types of humidifiers require more maintenance or are not as portable, so weigh these factors against your needs. For example, if you are buying an evaporative humidifier, check its wick filter and make sure it is simple and economical, so it does not cost you extra money and time whenever you need to replace it.

Most importantly, select a user-friendly humidifier that has convenient controls and features. For example, some users prefer to buy a humidifier that clearly shows the humidity level.


An automatically shutting humidistat, or hygrometer, is a blessing for almost all users because it turns off the device once your desired humidity level is reached. If your humidifier does not have a built-in humidistat, you can buy a hygrometer to monitor the humidity level in your room; it is highly economical.

Place of use

To save you time, money, and space, we recommend buying a humidifier model that suits the intended place of use. Besides being an inconvenience or creating an uncomfortable environment, adding excessive moisture to the air risks breeding mold and dust mites. It can also cause allergic reactions in some individuals. As a result, it is vital to choose the product that provides an optimal level of moisture.
