Best Humidifiers

If you live in a dry climate or you’re prone to dry skin, humidifiers can improve your life — and your sleep. That’s because they add moisture to your bedroom (or any other room), which can make you more comfortable and therefore make it easier to drift off to sleep. In addition to soothing dry skin, lips, and throats, there’s some evidence humidifiers can also help relieve headaches and kick the common cold.

No matter your reason for wanting a humidifier, you’ll have your work cut out for you when you start the search. There’s a huge array of humidifiers available, and they all offer different specs and functions. So how do you choose the right one for you? Start by considering the space you’re trying to humidify and your personal preferences, and then consult our roundup of best humidifiers to zero in on the right humidifier for your needs.

Best Humidifiers

Editor’s Choice

Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier

Pros: 

  • The 360-degree mist nozzle lets you point the mist away from electronics, bookshelves, plants, and so on, while multiple speed settings let you control the output. 
  • An automatic shut-off feature ensures the humidifier turns off when the water level gets low or the water tank is removed. 
  • The unit is quiet and easy to assemble and refill. 
  • It has an optional nightlight if you want to softly illuminate a baby’s room or make it easier to find your way to the bathroom at night. 

Cons: 

  • It can be challenging to keep the unit clean, because it has small nooks and crannies. 
  • The unit has a small footprint, but the tradeoff is that the tank is pretty small. If you use this all night long, you’ll probably need to refill it every day before bed.

Enjoy up to 16 hours of moisture-enriched air with the Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier, which features a 1.5-liter tank and multiple speed settings. An optional nightlight makes this humidifier multifunctional. 

Contender

Onson 2019 Humidifier

Pros: 

  • The ultrasonic design makes this extremely quiet, so it shouldn’t disturb sleep. 
  • The 4.5-liter tank should run for anywhere from 15 to 30 continuous hours (depending on the mist level setting). 
  • Three mist levels let you customize the unit to your preferences, while an auto shut-off ensures it won’t keep running if it runs out of water. 
  • The top-fill water tank is easy to refill, and both the tank and its stainless steel filter are easy to clean.

Cons: 

  • Running the humidifier at the higher settings might result in some wetness in the areas surrounding the humidifier. If you prefer those settings, you might need to place a towel under the unit. 
  • The humidifier features a humidity level reading, but its accuracy is kind of dubious.

The Onson 2019 Humidifier is easy to refill and clean, and it earns high marks for its use of BPA-free materials and a stainless steel filter. The 4.5-liter tank should last for a day or two before it needs to be refilled. 

Best Bargain

  • The 4-liter capacity allows for up to 60 hours of operation before a refill is necessary.

Cons:

How We Picked

The number of humidifiers on offer is pretty overwhelming, so it’s important to review all those choices with a critical eye. To shrink the list of available options, we took the following into account.

Cost

Humidifiers can range widely in price. Some of them cost less than $30, while others cost over $100. There are great options at both ends of that price range, so it should be possible for everyone to find a humidifier in their price point.

Ease of Use

“Ease of use” could refer to a number of factors, including how easy it is to refill the humidifier, how often it needs to be refilled, how easy it is to clean the humidifier, and so on. All of the humidifiers on this list should be relatively easy to care for, but some might require a little more maintenance.

In some ways, ease of use is a matter of preference. For instance, some people are annoyed by having to refill a humidifier tank every day, while others aren’t bothered by that chore. Take your personal preferences into account when choosing what’s right for you.

Functionality

Every humidifier on this list is going to add moisture to your bedroom (or several rooms, or your whole house). But beyond that, some humidifiers offer additional functionality.

This could look like the ability to diffuse essential oils, a built-in nightlight, the ability to remember your preferred settings, and so on. It’s up to you to determine just how many bells and whistles you want your humidifier to have (or none at all). We included models with a range of functions so you could settle on what’s best for you.

Size

Along with cost, this is an important practical consideration when you’re shopping for a new humidifier. It’s helpful to think about size both in terms of the space available for stashing the humidifier and the size of the space that you’re trying to humidify.

This will help you determine how large or small the humidifier’s tank needs to be (which will determine the square footage that it can humidify) as well as how large or small its footprint needs to be (depending on whether you’ll be sitting it on the floor, a narrow table, or somewhere else).

We included humidifiers with different tank sizes and footprints so you can find the right option for your space.

Sleepopolis Buying Tips

Ready to find the humidifier for you? Ask yourself the following questions to ensure the right fit:

  • What is your budget? Humidifiers can range in price from around $25 to well over $100. That’s a really big price range, so determining your budget can help you filter out options that aren’t going to cut it from a price standpoint.
  • Where are you going to use the humidifier? This will tell you how much you need to take size and shape into account. For example, if you’re planning to place the humidifier on a narrow nightstand, then you’ll want to look for an option with a space-saving design. If you want a humidifier that works across multiple rooms, you’ll need to look for one with a large water tank or a whole-house option.
  • Do you want multiple functions? Some humidifiers simply humidify, while others come with built-in nightlights, the option to diffuse essential oils, and so on. Determining whether or not you want a multitasking humidifier can help you narrow down your choices.

It can take some time to determine the best humidifier for your needs, but the effort is worth it. By making you more comfortable, soothing dryness-induced ailments, and helping you sleep more comfortably, humidifiers can seriously improve your quality of life. So don’t give up until you’ve found the best option for you.
