If you live in a dry climate or suffer from sinus or congestion problems, a warm air humidifier will be a great purchase. Just let it work in the background – either during the day or while you sleep – and enjoy the benefits.

There are, however, hundreds of different warm air humidifiers available on the market, which means choosing the best one for you depends on your personal requirements.

That’s why I listed the most important things to consider when making a purchase before spending hours searching the internet for the best available at a range of prices. Then, I read hundreds of reviews to check that they actually match up to customers’ expectations. So, read on to find out which warm air humidifier you should go for.

Things to Consider

There are hundreds of different warm mist humidifiers available, so trying to pick the best one for you can be challenging. Although people’s requirements will vary, there are a few specific points that you should bear in mind.

So, while there is no one-size-fits-all solution, here are a few things that you should consider before buying a warm mist humidifier.

1. Water Tank Capacity

Generally, the larger the water tank, the longer the run time and the larger space it will cover.

2. Features and Capabilities

Basic models just offer one or two humidifying settings, while high-end models have all kinds of features and capabilities, such as customizable settings, programmable timers, an auto shut-off feature, and a sleep mode. 

3. Control

Some warm mist humidifiers feature simple on/off switches and/or a turn knob, while others have full LED displays on the unit itself. Moreover, some models come with a remote control, while others are also compatible with Alexa, Google Home, and specific company apps.

4. Warranty

As with any product, there’s a chance that something will go wrong with a warm mist humidifier, so make sure the model you’re buying comes with a warranty. You should also check exactly what’s covered, as warranties are usually ‘limited’.
