Why Does Cool Mist Work for Babies?

When it comes to humidifier choices, you pretty much have two options: warm or cooling mist. The only big difference between these humidifiers is the way in which they produce humidity for a room. The resulting humidity is pretty much the same. A cooling mist humidifier is the safest choice for a nursery because there’s no risk of your baby getting burned by the appliance. There are other reasons you might want to choose cooling mist over warm mist.

Temperature of Mist

It’s relatively the same temperature, whether you start out with a warming appliance or a cooling appliance. So, don’t let this part sway your decision. Winner: Either.



A cooling mist humidifier never heats the water to create steam, while a warm mist one has heating elements. A warm mist humidifier could cause burns if a child gets too close or the humidifier spills. That’s never an issue with a cooling mist humidifier. Winner: Cooling mist.



A warm mist humidifier uses more electricity to work because it has to heat water to produce steam. A cooling mist humidifier uses the power of evaporation to create humidity, which means it uses far less energy – and that could be a cost savings for you. Winner: Cooling mist.

Type of Water


Whether you choose tap water or distilled, both humidifiers can turn it into effective humidity. If you have hard water, or water with lots of minerals, you might notice some white debris blown out of a cooling mist humidifier, which creates a little more cleanup for you to do, but it’s harmless. Winner: Warm mist.

Year-round Use

Both types of humidifiers can be used throughout the year, and both types can contribute to lower heating costs because humidity helps keep rooms warm. However, a warm mist humidifier could increase the temperature in a room more so than a cooling mist humidifier, which might be uncomfortable in the summer. Winner: Cooling mist.


Both cool mist and warm mist humidifiers need regular cleanings. Warm mist ones might fight the growth of bacteria, but not fungi. Cooling mist has a greater chance of allowing bacteria growth, along with fungi, but either way, these machines need to be kept clean. Winner: Either.

The overall objective winner is the cooling mist humidifier. You’ll get more bang for your buck, and you’ll get the same benefits as the warm mist humidifier, but you won’t have to worry about a nursery getting too warm, nor will you have to worry about your baby getting an accidental burn.

Why Would Your Baby Need a Humidifier, Anyway?

Your baby is perfect in every way, so why would you need extras like a humidifier, anyway? A great cool mist humidifier helps keeping your little one as close to perfect as possible. Dry air can wreak havoc on a little person’s sinuses. And a stuffy congested baby is an unhappy baby. Sinus problems can lead to sleepless nights – for your tot and you. Adding moisture to the air can help your baby breathe more easily, and that results in a happier baby (and parents).

An arid climate may do wonders for making shade feel better in the summer, but it does a number on our skin. The weather has a lot to do with how our skin feels, and for your baby, dry air could lead to irritated skin, dry patches, and more. You can help soothe that itchy dry skin by introducing a cool mist humidifier to the nursery.

Colds, flus, and other illnesses are going to happen. You can do your best to protect your little one, and a humidifier is one way to keep some of those icky bugs at bay. Once your baby has a cold or flu, though, you may think that meds and comfort are the only ways to ease the symptoms. Nope! Break out that cool mist humidifier and raise the humidity in the rooms your baby spends time. The moist air can help clear out nasal passages, soothe the sore little noses, and help your baby breathe better.

Humidifier for Babies: Features You’d want to have

You want to make sure you get one of  the top rated cool mist humidifiers for babies, so look for features that make the unit better, or that make your life easier.

Noise Level

Many babies sleep more soundly when there’s a bit of white noise happening, and many humidifiers can provide that sound. Some are louder than others, but the cooling mist humidifiers seem to offer a hum from the fan that can be soothing. So you don’t have to worry about when to use and when not.

Auto Shutoff

An auto shut off option is more than just convenient. It can be considered a safety feature, at least for your humidifier. The last thing you want to do is use your humidifier once in the nursery, and then it run out of water, but keep going, only to burn out a motor.

Large Capacity

The larger the container that holds your water, the better because you won’t have to refill the tank all the time. If you’re using an intermittent function, though, this might not matter as much.

Timer Function

If a humidifier doesn’t include a humidistat or other smart controls to help keep the humidity levels precisely where you want them, you can get by with a timer function. Set it to run just the same number of hours you plan to put your baby down for a nap, and it’ll shut off after that set amount of time.

Diffuser Capability

Check with pediatrician first about using essential oils for your baby. If you get the green light, then you might want to find a humidifier that allows you to use essential oils in the tank or in a tray to give your baby a soothing scent in their nursery.

GENIANI Ultrasonic Cool Mist Humidifier

Ultrasonic Cool Mist Humidifier - Best Air Humidifiers for Bedroom

The size of the GENIANI ultrasonic cool mist humidifier may be the best for babies because it isn’t huge, but it has a surprisingly large tank for water. This unit should fit on the dresser in any nursery, but it holds up to 3 liters of water. You’d expect a much larger humidifier for capacity at that size. And with a 3-liter capacity, you should be able to get up to 24 hours of vapor. The nozzle of this unit is adjustable, too, which means you can point the nozzle away from your baby if that makes you more comfortable.

As is the case with most cool mist humidifiers, this one comes with an automatic shut off, in case the unit runs out of water. Plus, this humidifier is nice and quiet, so it shouldn’t disturb your baby’s sleep. There’s a nightlight option, too, which some babies prefer, and it makes it easy for you to navigate the nursery in the dark. You won’t be able to use essential oils in this unit, but if that’s not important to you then it isn’t much of a negative. One thing that was agreed upon is that this humidifier can be difficult to refill, as the cap is at the bottom, and the handle for the unit is on top.

Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier

Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier

One of the best things about the Pure Enrichment MistAire cool mist humidifier is its size – it’s a great unit for a nursery and for keeping the humidity level high for your baby. If you’re just looking at the features of cooling mist humidifiers, then it’s good to know that this one includes almost all the standard features you’d expect, such as auto shutoff, a nightlight, and quiet operation. Some people aren’t a huge fan of the LED “on” light, as the little red light is quite bright and won’t shut off, so it won’t work for your nursery if your baby prefers pure darkness.

Although this humidifier comes with a cleaning brush, the actual job of cleaning this unit can be a chore, at best. You’ll need to clean the tank out every day, and then let it dry before refilling again. Once per week, it’s suggested you give it a vinegar bath, too. Still, the tank is a good size at 1.5 liters, which will allow this humidifier to pump out cooling mist water vapor for up to 16 hours. So, you may only need to fill it every two days. Keep in mind that leaks are commons, so watch for water.

If you’re looking for a cooling mist humidifier for your baby that can pump out vapor for two nights in a row without refills, this might be the one for you.


  • Auto shutoff
  • Includes cleaning brush
