If you are in a hurry to figure out what is the best baby humidifier, we recommend “PurSteam Cool Mist Humidifier” as the best one.

The word humidity doesn’t always have a positive connotation. It makes most people think of hot, sticky weather and frizzy hair. But in dry climates, a certain level of humidity can help with health issues. That’s what humidifiers do—they moisturize the dry air which provides a host of benefits for an infant.

You fill the device with an amount of water. That water is turned into steam or mist and then sprayed into the room.

Types of Baby Humidifiers

Humidity is created in two different ways: cool mist and warm mist. These are also the two main types of humidifiers. There are humidifiers that combine both types of mist—making you able to switch between both.

Cool mist

Cool mist humidifiers produce cold water particles. This cold water is ideal for humidifying. It’s also safer as it doesn’t create any risk of burns.

These humidifiers usually cost less than the ones creating hot mist but need cleaning more often. The water in the reservoir needs to be changed daily.

The cool humidifiers have two subtypes:

  • Evaporative humidifiers: The air is sucked inside through an internal ventilation system. The air is then directed over a wick filter that has absorbed the water. The air takes this humidity and is then pushed back out.
  • Ultrasonic humidifiers: A small plate generates vibrations at an ultrasonic frequency. That breaks up the water particles creating a mist.

Hot Mist

With these humidifiers, the warm mist is blown out of the device. They are more effective against bacteria and can kill germs and viruses. Also, warm water increases humidity. The filter of this type needs to be changed less, and they’re quieter in use as they don’t have a fan.

The downside is that hot water has a higher risk of burns. This device is ideal to use when it can be placed out of reach of your little one.

This type of humidifier is also used more by people living in cold climates. The warm mist heats the room to a more comfortable temperature.


Whether you choose to go for warm or cool, there are several choices of style when it comes to humidifiers for your baby’s room:

  • Tabletop: The most popular choice for a nursery, as it is easy to maintain and portable. They only work for the room they are placed in, so you may need to buy several for your home.
  • Console: Much larger than tabletop humidifiers, these models are not portable but will work for the entire house.
  • In-duct: This style of humidifier is installed into the air ducts within your home. While it’s easy to maintain and works for the whole house, it’s a big deal to get the system set up.

Benefits of Baby Humidifiers

Moisturizing is always presented as something positive, e.g., for hair and skin. It’s no different with the air. As we are constantly in connection with the breathable air in our room, the extra humidity also affects us.

Germ Killer

The first advantage is that there are fewer bacteria and germs in the air. Dry air is a breeding ground for them, so adding some moisture to that reduces their chances of survival.

Just Breathe

If you’ve ever been in an enormously hot and dry climate, you may have experienced a sore or rough throat while breathing. This is similar to what happens when you continuously breathe in dry air in your room. Humidified air makes it easier to breathe, loosens mucus, soothes dryness and irritation of allergies and colds. Scientists have also researched the influence it has on asthma.

Sleep Like a Baby

For your baby, having a humidifier running in the background might help them to doze off. Especially ultrasonic humidifiers, which produce a soft white noise that can benefit sleep.

Dry Air Equals Dry Skin

Dry air equals dry skin, so the extra moisture added to the air will also have a positive effect on baby’s skin. Babies have extremely sensitive skin, so moisture in the air can prevent red patches, chapped lips and symptoms of eczema.

What to Look for When Choosing the Best Baby Humidifiers?


Humidifiers help to kill the germs in the air, but you have to make sure you clean them enough. Otherwise, mold can start to develop on the inside of the device. This mold will be pushed out together with the mist and make things worse instead of better. Also, it’s not a bad idea to disinfect your humidifier once in a while.

The maintenance also includes changing the filter and water. The water should be changed every day, for the filter you should follow the instructions of the manufacturer. It helps to keep the humidifier clean if you use boiled water.

With all these things to consider about maintenance, you might want to select an easy-to-clean product.

Warm vs. Cold

Before you head out to the shops, decide on what type of humidifier you want. Some produce hot mist, others a cold one. Or you might opt for one that has the ability to switch between both functions, so you are flexible in selecting which is best for that moment.

A portable tabletop option is the easiest to set up and use straight away, but if you live in a dry climate, you might want something that can humidify the whole home.


Some babies might like white noise, but most parents don’t. Many products now on the market will advertise how quiet they are. A piece of advice is to look into one of these if you are sensitive to noise.

Special Features

The best humidifiers for baby can be equipped with handy extra features, such as:

  • A timer.
  • An auto shut-off.
  • A humidistat to monitor the humidity level.
  • Antibacterial features.

Natural Ventilation

Rooms that have none or minimal natural ventilation such as a window are the ones where you should definitely use a humidifier. In dry climates, you might open the window trying to get some fresh air, but just bring in even more dryness. In these climates, a stronger humidifier is required.

Room Size

The bigger the room, the stronger the type of humidifier you need. A piece of advice is to check which surface area they cover before buying.

Tank Size

Humidifiers have a reservoir that you fill with water. Once this water runs out, they stop working. If you want yours to last through the night, make sure you opt for one with a bigger tank.

Best Baby Humidifiers Reviews

It’s clear that there are many aspects to take into consideration when looking at the best humidifiers for baby. If the benefits have convinced you to invest in one, it’s time to start shopping. These reviews will help you narrow it down.

1. PurSteam Cool Mist Humidifier – Best All-Round Humidifier

The PurSteam Cool Mist Humidifier is a basic humidifier with all the needed features. It’s a great tool to add some extra moisture to medium-sized rooms.

Like many other humidifiers, this device has an auto shut-off. This means that once the water reservoir is empty, the humidifier stops working. It’s a way to protect the machine, as it can lead to damage when it runs without water. This built-in protection tries to extend the lifespan of your product.

The manufacturers advertise the device as being “whisper-quiet,” and that’s exactly what some users describe as their favorite feature. A bit of white noise might help your little one sleep, but too much background sound might cause the opposite.

Another convenient feature is the bountiful 11 mist control settings. You can adjust the direction and speed of the mist to your preference. This way, you can point away the released water from any object in your baby’s room.

What’s great for babies is the nightlight function of the humidifier. It casts a soft light on your child’s room, making it a cozy area to sleep. Lastly, the PurSteam Cool Mist Humidifier gives you all of these features for an affordable price is the most significant advantage.

The biggest downside of this device is the reported difficulty of refilling it and putting it back into its place without spilling. When being moved, the tank can leak. Some parents even found puddles of water under the machine while it was operating.


  • 11 mist control settings.
  • Whisper-quiet.
  • Nightlight.
  • Affordable.


  • Sometimes leaks.

2. Homech Cool Mist Humidifier – Best 360-Degree Humidifier

The Homech Cool Mist Humidifier aims to be a quiet, mid-sized humidifier that’s easy to keep clean. The 360-degree rotating nozzle makes sure all the air in the room is moisturized.

The quiet weaken water-flow technology ensures your little one will not lose any sleep with this device in the room. The tank can hold 1 gallon of water which equals about 60 hours of humidifying. This is, however, in ideal circumstances.

The manufacturers have really tried to equip the machine with extras that help you to keep it clean and battle bacteria and mold. The dustproof sponge prevents dust from coming in and extends the humidifier’s life.

The tank is easily separated from the base by a handle. Filling and cleaning is facilitated by the wide opening. You can put your hand completely inside to scrub all the sides. The device has a brush included that is perfect for cleaning the base.

Inside the machine, the mist guide tube drains after use. The fan also keeps rotating another three minutes after the fog has stopped. Both features try to avoid mold growing on the inside.

A minus is that the tank isn’t clear. With a device that puts the focus on the sanitary aspect, it would be a helpful trait. It’s much easier to spot mold in a transparent tank.


  • Easy clean—wide opening tank, drainage tube and extra fan rotation, brush included.
  • Handle on tank.
  • 360-degree turning nozzle.
  • About 60 hours with one tank.


  • Clear tank would be easier to spot mold.

3. LEVOIT Humidifiers for Large Room Bedroom – Best Humidifier With Remote

If your baby’s room is on the large side, or you want a powerful device for a medium-sized room, the LEVOIT Humidifier is a great choice. The tank fits 1.5 gallons of water, which equals about 36 hours of humidity on the lowest setting.

This humidifier blows out both warm and cold mist so you can set it to your preference. Warm mist is great during wintertime and even helps to heat up the room, while the cold option is ideal during summertime.

What’s perfect for your baby’s room is that the device is equipped with a remote. This means that you can operate it from a distance. If your little one is sound asleep, you don’t have to enter the room, stumble past toys and furniture in the dark and risk disturbing them.

You might not even need the remote, as the humidifier has a humidity sensor. It measures the current humidity in the room and will automatically diffuse mist necessary. Or, you can just put on the timer so the device will switch on and off at your selected times.

The screen has LED lights that you can switch off completely. But in an infant’s room, it might serve as a nightlight so you could leave it on. A nice extra is that the humidifier has an aroma box. On this, you can add your—or your child’s—favorite essential oil and it will be diluted into the room as well.

As a downside, you might consider the device to be bulky. Another disadvantage is that manufacturers recommend filling the tank with distilled water—though this is a good choice with any humidifier.


  • Large tank.
  • Remote avoids disturbing baby.
  • Warm and cool mist.
  • Timer.
  • Humidity sensor with auto-diffuse.
  • Aroma box.


  • Bulky.
  • Recommended to use with distilled water.

4. Honeywell HCM350W Germ Free Cool Mist Humidifier – Best Tap Water Humidifier

The Honeywell HCM350W Germ Free Cool Mist Humidifier combines a modern look with all the basics an excellent humidifier needs.

A 1-gallon tank delivers 24 operating hours of the device if it’s on the lowest setting. A big upside is that you can use regular tap water to fill it up. The ultra-violet light technology shines on the untreated water, killing bacteria, mold and fungus that might be in it.

The most extensive downside of the device is that it needs to be refilled daily. And that’s when it’s running on the lowest setting only, so you’ll probably need to refill it even more frequently. This process is quite cumbersome.

The manufacturer has tried to facilitate the filling. A large recessed tank handle makes it more accessible. Also, the large tank opening helps you during the weekly cleaning time of the humidifier.


  • Runs on tap water.
  • Large recessed tank handle.
  • Large tank opening—easy to clean.


  • Needs to be refilled daily.

5. TaoTronics Cool Mist Humidifier – Best Ultrasonic Humidifier

This ultrasonic humidifier fills your little one’s bedroom with fresh water-particles at three different mist levels. You can set your desired level.

The TaoTronics Cool Mist Humidifier is guaranteed to last through the night with its 1-gallon tank. The minimum operating time is 12 hours, and this can be prolonged to 30 hours if you turn down all settings.

The device has an LED display which you can completely switch off in case it’s disturbing your baby. There’s no need to use it as a nightlight as the humidifier also has that as a feature.

Some humidifiers are haunted by mold, even when cleaned weekly. This device tries to battle that with a microporous cartridge. This cartridge filters the water from bad odors and micro-organisms.

A downside of the device is that it’s not very easy to clean. Also, if you shut the whole thing off, you lose all previous settings. This means you have to reprogram the device again to your preferred settings.


  • Display can be put in sleep-mode.
  • Three mist levels.
  • Microporous cartridge to filter water.
  • Nightlight.


  • When turned off, it loses all previous settings.

6. Ultrasonic Cool Mist Humidifier – Most Powerful Humidifier

The Ultrasonic Cool Mist Humidifier features a stylish egg-form design with a clear water tank. It won’t just help your baby breathe easier but it’s also a delight for you to look at. Even at night, it will be clearly visible as it’s equipped with an ambient nightlight.

It’s a powerful device, producing up to 250 to 300 milliliters of mist per hour. The mist level is adjustable, so it’s up to you to select your preferred strength. However, the more mist it produces, the faster the tank runs out. With the 360-degree rotating nozzle, no corner is left un-humidified.

An advantage of this device is that it functions filter-free. With some devices, it’s the filter causing the device to become noisy. Also, you save the money that you’ll otherwise spend on changing filters every few months.

Even if the device is filter-free, some parents have reported it to be a bit noisy. It’s the water causing this, and it’s mostly a bubbling sound. It might turn out to be the perfect sound for your little one to relax to.


  • Stylish design.
  • Filter free.
  • Powerful.
  • Adjustable mist level.


  • Water makes noise.

7. Crane Filter-Free Cool Mist Humidifiers for Kids – Best Humidifier for Kids

The Crane Filter-Free Cool Mist Humidifiers for Kids are very suited to humidify your little one’s room. They are designed with different adorable animal designs such as an elephant, bumblebee and cow.

The 1-gallon tank is supposed to last about 24 hours, providing enough humidity in your baby’s room for a whole night.

Inside the base is antimicrobial material which is created to reduce mold. While that’s making it easier to keep the inside clean, it’s up to you to sanitize the outside. That can turn out to be a time-consuming task with all the cracks and crevices of the animal design.


  • Antimicrobial material in base reduces mold.
  • No filter.
  • Adorable design.


  • Outside difficult to clean.
