How We Selected

Those looking for a humidifier to cover larger spaces will appreciate the 6-liter water tank and powerful mist output of this Levoit unit. Its large capacity reduces the number of times you’ll need to refill it, and allows it to function for up to 60 continuous hours on the lowest setting.

A handy remote control makes it easy to change the settings from across the room, or you can use the Auto setting, which makes the adjustments for you. You can also use the convenient timer setting to avoid leaving the unit on when you’re not using it.

Even though this humidifier is on the lower end of the price spectrum, it still offers most of the same bells and whistles found on more expensive models.

Its auto-shutoff feature turns off the power whenever the water level gets low, or when the tank is removed for cleaning or refilling. The night light is also a nice perk, and one that isn’t found on many other models at this price, making this a great choice for kids' rooms.

This unit's 1.5-liter water tank makes it effective for rooms up to 250 square feet, and it will operate continuously for up to 25 hours.

Weighing just half a pound and with a 3.4-inch footprint—small enough to fit in your car’s cup holder—this Geniani unit would be well-suited for those who need a compact and portable humidifier for traveling.

Its light weight makes it convenient for tossing into a suitcase or backpack, and an optional night light is a nice perk, as well. Despite this small size, it’s still designed to be effective in areas up to 65 square feet in size, and also offers three settings to choose from.

This unit is also designed not to spill its water tank if it’s accidentally knocked over.

If you prefer to control your appliances with your phone, this Levoit model and its app connectivity could be just what you’re looking for.

You can enable voice commands to control your unit hands-free, and can even program preset schedules to work with your personal routine. This unit is also well-suited for use around newborns or in a nursery, thanks to its low 26-decibel noise level.

We’re big fans of the adjustable nozzle, which can be rotated 360 degrees, and the bright LED display that allows you to easily see the current humidity level.

It wouldn’t be practical for areas over 175 square feet, but if you’re just looking for a humidifier for a small space, or for personal use like keeping on your desk, this could be a good fit. Despite its small size, it’s still able to operate for up to 10 hours, making it useful for those who need a model that can operate overnight while they sleep.

The single-button control makes it simple to use, as well, allowing you to select either of the two mist settings or power on the night light.

This may look like a fun little buddy, but it's actually a fully functioning—and effective—humidifier. It comes in nine different designs—eight of which are various animals, and one token train— and has a dial that's easy for both kids and adults to control. It has a one-gallon water tank, and it works in rooms as large as 500 square feet.

While a lot of us use essential oil diffusers for the pleasant scent and aromatherapy benefits, they don't offer a ton of help when it comes to functioning as a humidifier. This model, however, is a humidifier first, and will actually help hydrate your room for up to 50 hours.

It also has an essential oil tray that allows you to add your favorite oils, which will then be integrated in the mist, making any room smell great. Since it's designed for use in the bedroom, it also runs incredibly quietly, and automatically shuts off when it runs out of water.
