8 Best Baby Humidifiers of 2023, According to Experts

If you're looking for a humidifier that will last all night and help keep baby's room clean and moist, this one from Honeywell does the trick. This humidifier uses ultra-violet light designed to help get rid of germs and bacteria. Our Lab pros loved that it's super-easy to clean, thanks to its dishwasher-safe parts, and the large opening makes it simple to refill the tank each night (which is especially important in a baby's room since you'll want to clean it and replace the filter quite often).

In our tests, Honeywell lasted for a full day on the lowest setting, so you don't have to worry about hopping out of bed in the middle of the night for a refill. The soft fan-like sound won't keep baby up all night and provides soothing background noise for the nursery.

This smaller, budget-friendly option comes in a variety of pretty colors and lasted an entire day on the lowest setting in our tests. If you have multiple kids sharing a room, this humidifier is a great option because it has two separate vents that can point in different directions to ensure that the entire bedroom is covered.

At less than $35 for some colors, it's also a good value. Unlike some other options, this humidifier doesn't use a filter so you don't have to worry about spending additional money changing and purchasing new ones every few months. Since the tank is on the small side, the auto-shutoff is exceptionally convenient, as is the alert light that lets you know when you need to add more water to the tank. Our testers note that they like the variability of the output depending upon the size of the room or need for humidity, and appreciate how small it is (nice for fitting in the nursery).

Stay connected to your little one's humidifier from any room in the house with this unit from Safety 1st. Our testers love that you can control humidity levels on this humidifier virtually from your smartphone app so there's no need to worry about waking baby up to come in and alter the settings. It's a bit larger than some other units since it holds a gallon of liquid, but it features an easy top-fill tank that makes filling it a breeze.

Once you've connected to the app, testers found it simple to use and loved the variety of setting options. A few reviewers noted having trouble connecting to the app. You can also access other Safety 1st smart products, such as the baby monitor and the smart outlet, through the app. The unit's night light, and the intense, easily adjustable humidifier power are great for keeping a baby calm and comfortable throughout the night. We also appreciate that the timer allows you to turn it on or off at specific times or humidity levels.

Some little ones need absolute silence to catch some quality zzz's, and this humidifier by Pure Enrichment may be just the thing you're looking for. In Lab tests, we found it's surprisingly quiet while in use and is ideal for small rooms since it has a 1.5-liter water tank. This model, which has over 79,000 five-star reviews on Amazon, also has two different speed settings, a night-light mode and a nozzle that spins 360 degrees to direct mist wherever needed. It comes in three different sizes, so it's easy to find the right one for your room that will last long enough so you won't have to wake up and refill it in the middle of the night. But if you forget to add extra, the automatic shut-off means once the water level gets too low, it will shut off on its own.

Also known as steam vaporizers, warm mist humidifiers use warm instead of cool mist to keep air moist. While we usually recommend cool mist options to prevent burn hazards, warm mist models like this version from Vicks can be more comforting during cold winter months; they also tend to be quieter than cool mist version, good for sleeping babies. Just make sure the unit is in a secure, elevated position, out of reach from any exploring toddlers who might be in the home. For older kids (2 and up), you can use the humidifier with Vicks VapoSteam for medicated vapors to help relieve colds, congestion and coughs. Just note that unlike some others, this humidifier requires changing a filter.

Turn your baby's nursery into a dreamscape with this adorable colorful humidifier that doubles as a projector. In addition to the boost of moisture, it has the ability to project sea, safari and starry images on the ceiling to help your little one fall asleep. This model also works with Vicks menthol VapoPads to help older kids with congestion and uses cool mist that's safe for all ages. With a one gallon tank capacity, it's best for medium sized rooms, and we found that this filterless option still ran for an entire day on the lowest setting in our tests. Our testers appreciate how easy to use this humidifier is, and have found that it's quiet enough to not disrupt a sleeping baby. We've also found that it features a relatively wider opening than some other options which is great for easy filling and cleaning.

For a bigger room or a nursery with more than one child, the OasisMist from Levoit is a good fit. It's designed for large spaces, covering a 600 square foot space with a massive 10 liter tank capacity, which means it can run for an extended period of time with less refills (but also tricky to move around). It's easy to fill too, with a top-down tank and a lid you can remove with one hand. Packed with smart features, you can do everything from monitor humidity in real-time, set your target humidity and create schedules, all from your phone. There's even the Auto Mode that can help maintain the correct humidity level for your plants.

Cheer up any room with this little elephant while helping clear sinuses and keep air moist. Besides being an adorable addition to your nursery, this animal-themed humidifier has a base that our Lab experts found easy to clean and is quiet when operating. It comes in 11 different designs, including unicorn, monkey and train themes. (If you prefer a more streamlined look, try the Crane Drop Cool Mist version which won't look out of place in a living room or adult bedroom.) There's an optional filter slot, so while one isn't required to make the humidifier work properly, you can choose to pop in a filter to clean the air while providing moisture. If your kiddo happens to need a darker space to sleep, know that some reviewers say the built-in light can be pretty bright.
