Best Steam Humidifier – Buying Guide


Coverage area

Before you get a steam humidifier, it’s a good idea to roughly work out the square footage of area that it can cover. Some smaller devices would struggle in larger rooms. If you’re not sure then it’s best to get one that is a little bigger. 

Size and tank capacity

Tank capacity is going to have a large effect on the runtime and coverage area. A large tank capacity will also mean a bigger unit and one that is heavier. While it may make sense to get a large humidifier, it’s worth considering if you need it to be portable, whether you have the space for it and how it needs to be refilled.


Some of these machines can help you to sleep but not if there is an annoying buzz next to you. It’s a good idea to look for a near-silent humidifier if you want one for your bedroom. Many of the top models make a very minimal amount of noise.

Additional features

The functionality on some of these models is brilliant. An auto shut off feature is a good idea for safety once the tank is empty. On top of that can be the ability to add essential oils, a timer, the ability to set your preferred humidity level, cool mist function and different steam settings.

Continuous run time

The run time will be mainly linked to the tank capacity and how much steam can be generated at any one time. It’s worth bearing in mind that the advertised run time on many of these models is what it can do on the lower settings. On the highest setting, the run time may be a lot shorter.
