Humidifiers are great for helping babies, toddlers, and bigger kids breathe easier during allergy and cold seasons. Additionally, in the winter months, when the air can be dry and uncomfortable, humidifiers help to add moisture to the air. The best humidifiers have the right water capacity for your needs, an auto shut-off feature, and will be able to cover the square feet of your baby's room.

Reviewed & Approved

Our top pick is the Levoit Humidifier because it's durable, easy to use, and quiet. If you're shopping on a budget, try the PureGuardian 14-Hour Cool Mist Ultrasonic Humidifier.

Choosing the right humidifier can be difficult since your choice will largely depend on the size of your room and how you decide to use it (Will you run it all night or just use it intermittently?). Once you've determined the size you need, it also helps to consider features like durability, noise level, ease of cleaning, nightlights, and more. We researched popular options from trusted brands with these features in mind.

Here are the best humidifiers for babies to help them breathe easier and sleep better.

We love this simple humidifier for its overall value.

You can choose among three mist settings, all of which are very fine, so you won't end up with a puddle of water under the humidifier after running it for a few hours. It's also equipped with a humidity sensor that allows it to automatically adjust the mist level to provide comfortable humidity at any time.

If you plan to use it while you sleep, it has a Quiet Sleep Mode that runs as low as 24dB and will automatically turn off display lights. It also doubles as an oil diffuser, so you can add in a little aromatherapy when your little one is recovering from a cold (always consult with your pediatrician before doing this, though).

What to Look for in a Humidifier 

Water Capacity 

Because a humidifier works by putting moisture back into the air, it’s important to double-check the water capacity. When you’re ready to purchase a humidifier, determine the size of the room the humidifier will be in and whether there’s enough water to reah the entire room. Too little or too much water can ultimately cause damage and/or not solve sinus/dry air issues.

Some humidifiers can hold a lot of water but give you the option of how much humidity you can put back into the air. For example, a humidifier with a large water capacity may work better for you if you plan on running it all night long at a high speed. However, if you need it in a small room for just a few hours at a time, you can opt for a smaller water capacity. 

Auto Shut-Off

One of the most important features to consider when shopping for a humidifier is an auto shut-off option. This not only ensures the humidifier is turned off when the desired humidity level is reached but also if it runs out of water. 

Many families like to leave a humidifier on while everyone sleeps, but this means that it can run out of water when no one is watching. With the auto shut-off option, the humidifier avoids any potential damage and you and your family can sleep in peace.

Room Size

How humidifiers work depends largely on the size of the room the humidifier will be staying in. Humidifiers for nurseries, or rooms that measure around 250 square feet, will differ from those that made for larger spaces. 

For example, if you buy a humidifier that’s too small for a large room, it will not offer enough coverage and be less effective. And a humidifier that's too big can actually cause water damage over time by putting too much moisture into the air. So,choose a product designed for the size of the room you will be using it in.

Frequently Asked Questions

  • Can my baby sleep with a humidifier?

    Yes, it is safe for your baby to sleep with a humidifier, which is also called a vaporizer. Only use a cold-mist humidifier, as hot-water vaporizers pose a risk of burning your baby. Set up the humidifier close to your child's sleeping area as the highest concentration of moisture will be nearer to the product. However, be sure it is out of your baby's reach so they can't topple it over.

  • Can I use tap water in a humidifier?

    Yes, assuming your tap water is drinkable, it's fine to use tap water in your humidifier. If your water has a high mineral content, you may notice mineral deposits (white dust) on your humidifier. If so, you can use distilled water if you'd like.

  • How far should a humidifier be from a sleeping baby?

    Place the humidifier close to your baby's crib to get the most benefit from the moist air it creates. However, you want to ensure it is out of your baby's reach so that it can't be accidentally knocked over.

  • Can I use essential oils in a humidifier?

    Before your baby is 6 months old, it's best to avoid using essential oils in a humidifier as your infant's lungs are still developing. Also, various oils have different safety concerns and may impact your child in unique ways. If you do want to use essential oils for your older baby or toddler, consult their pediatrician to make sure you use them in a safe manner.

    Many humidifiers have a diffuser feature specifically for essential oils. If yours doesn't, and your doctor has okayed oil use, you can usually put the oil directly in the reservoir along with the water.
