Coming in 3 different color options, black, blue, and grey, the TaoTronics TTAH-001 Cool Mist Humidifier has an undeniably attractive and elegant appearance. Not only that, but it also has many cool features that are worth appreciating.

As the name suggests, it is a cool humidifier, belonging to the classification of ultrasonic humidifiers which is a very reliable type. To be more specific, the machine uses ultrasonic waves to help the water molecules being distributed evenly. This will help you feel more relaxed and comfortable.

In addition to that, the ultrasonic application does contribute to reducing the noise, especially when it comes to the baby’s rooms. The noise level will be no more than 38 dB, which is perfect for a disturbance-free sleep.

What is more, you can choose either continuous or intermittent misting modes. The humidifier will help you sleep continuously thanks to a 4-liter tank capacity, which is equivalent to about 12 – 30 hours. That is fantastic, isn’t it?

Plus, you are guaranteed with its LED light system, which is completely convenient. The built-in humidistat is capable of displaying the current relative humidity (also known as RH). Besides, the manufacturer has installed the nightlight and sleep mode so that you can turn on or off the light depending on your needs.

Furthermore, it features a microporous filter cartridge. In fact, it is a small pored membrane that is used to sieve various substances, especially micro-organisms, when the water passes through. Eventually, the mist coming from the humidifier will be fresher and healthier for humans.

However, you should bear in mind that this humidifier is not suitable for being added with essential oils or placed on the blankets. If you did so, the device would be seriously damaged due to the leakage problem. Instead, you can use pure water for greater efficiency.

2. Elechomes SH8820 Top Fill 5.5L Humidifier

Best Quality Humidifier for Baby

The Elechomes SH8820 Warm and Cool Mist Humidifier is a multifunctional humidifier that removes dry air, allergens, and bacteria in the air through the three-layer mist setup.

Cool mist is a decent standard and it will moisten the air gradually, but warm mist accomplishes this 30% faster and it will eliminate allergens and bacteria in the air which are harmful during this process. You can use the warm mist setting in the winter and cool mist in the summer.

Additionally, you may also like the display and clarity of each function. The LED screen is great. It is so bright and clear that it will never confuse you. Of course, everything will be better with a simple and practical device than a complicated one.

One of the most favorite features is the smart/automatic moistening. With the auto option, what you need to do is to preset the humidity level (from 30% to 80%) and then, just let the device do the rest. But that is not all… If the room’s level drops below your preset mode, it will automatically start moistening again until it is close to your set level.

And for those who own many essential oils and are looking forward to using them, this humidifier is a good choice. Unlike other humidifiers that do not have an aroma option, this device has its own separate tray where you can sprinkle a few drops on a small cotton pad and it will circulate that smell when turned on.

Moreover, it is designed with a large water tank to moisten up to a 750 square feet room. The capacity of the tank allows a continuous spray of about 12 – 40 hours.

Nevertheless, the humidifier will drain much faster in warm-mist mode, high mode, or both.

3. LEVOIT Dual 100 Humidifiers for Bedroom

Best Cool Mist Humidifier for Babies

If you are looking for a humidifier that is compact and convenient, then the LEVOIT Dual 100 Cool Mist Humidifier will definitely satisfy you. So why is it? Let’s take a look at its features.

First of all, thanks to the 360-degree cylindrical design, it is favored by many people. The white glossy finish has brought it a rainbow effect when light reflects off its surface. Besides, with a height of 10.6 inches and a width of 7 inches, you can place it anywhere you want, even on the shelf or on the tabletop.

Secondly, in terms of cleaning, this humidifier excels at it. To be more specific, the tank is removable, which means you can take it off from the base when doing the cleaning. This task requires no complex disassembly and reassembly, so cleaning is absolutely simple. Besides, to refill the tank, all you need to do is to remove the lid and then pour water directly into the tank. Everything is so easy, isn’t it?

In addition to that, it features a set of buttons that makes the device easier to operate. In fact, there are only 2 buttons on the face of the humidifier. The first one lying at the bottom is the power button which allows you to press repeatedly to change the mist settings, from low to medium, and high. Above that button are 3 LED lights indicating different power levels.

The other button has a crescent moon on it, used to activate the sleep mode. This mode, when turned on, will play a role of turning off all the LED lights, giving out no lightning so that you can sleep soundly. Also, the built-in humidity sensor will be automatically activated in this mode, maintaining an adequate level of humidity and thus, making the air more breathable and fresher.

Moreover, this device acts as a humidifier and a diffuser, as well. You can add some drops of your favorite essential oils and spread them into the air. Also, the manufacturer has applied the Spiral Air Duct technology in the device, assisting in turning the water into a fine mist that is able to spread throughout the room in a short period of time.

Though it is a great and lightweight humidifier, the delivery quality is not really good. You should ask the sellers to wrap it carefully to prevent unwanted scratches.

What to Consider when Buying a Humidifier for Baby


Firstly, please calculate the room area to choose the machine with compatible water tank capacity. Large rooms with small devices will not provide enough moisture.

Conversely, if the humidity level is too high, the phenomenon of condensation will appear and give bacteria and molds the opportunity to multiply, grow, causing unwanted effects on the health of everyone in the family.

According to this factor, there are 2 types of humidifiers:

Low-capacity Humidifiers: This is mainly used by a parent or a baby only in a not too large area. This is the most commonly used machine.

High-capacity Humidifiers: You can encounter this type of humidifier in such a large area like kindergartens. Or you can see it in the room where the baby sleeps with his/her parents in a room.

Type of Humidifiers

This is determined based on how it works, there are two common types of machines on the market: cool humidifiers (the most used is ultrasonic humidifiers) and warm humidifiers.

Ultrasonic Humidifiers

It can be understood that this device uses ultrasound to convert water into mist and then blow them out through the ventilation system to increase the moisture in the room. The mist blown out is very cool, so it is not dangerous to users.

It is also energy-saving and produces a very low noise level or even no noise when operating.

However, it is quite easily broken coming with a slightly loose water tank lid.

Warm Humidifiers

The machine uses temperature to vaporize water into steam and bring them into the air.

They usually come in many diverse models.

Besides, it is easy to use, disassemble, and clean.

Nevertheless, it is slightly energy-consuming. It can pose a threat if left in the baby room as when they move or crawl around the room, they may break it down and burn themselves.

Noise Level

Each type of device will have different noise levels. Choose a quiet humidifier, such as an automatic ultrasonic humidifier that uses high-frequency sound waves to guarantee a sound sleep.

Period of Humidifier Operation

Humidifiers should be cleaned and filled with clean water after 24 hours of operation. This is the ideal amount of time for busy parents who do not need to check the water level regularly.

More importantly, always make sure that the humidifier you choose has an automatic shut off mode. This will ensure that there is no accident of explosion, in case you forget to add water to the water tank.

Child-friendly Design

Humidifiers have become an indispensable part of your child’s daycare and bedroom. Therefore, manufacturers create a range of machines that are child-friendly in both color and shape.

You can freely choose from the animals or colors that your child likes such as Freddy the Frog, Merlin Dragon, and even Hello Kitty.


Should You Use a Warm Humidifier or a Cool Humidifier for Baby?

Unlike what some parents usually think, studies suggest that a cool humidifier should be used for babies and toddlers as they can prevent the growth of bacteria in the air better than a warm humidifier.

The water temperature in the tank of warm humidifiers is always high, so warm humidifiers can pose a risk of burns for children if the device breaks.

On the contrary, a cool-mist humidifier also offers the same benefits as the warm one. Along with that, in cool humidifiers, there is no hot water, so children will be safe from unneeded burns.

How Often Should You Refill the Humidifier?

Normally, if you use the device continuously throughout a day, you should refill the tank every 24 hours. Some humidifiers may require fewer times of refilling, so you should check it carefully in the instruction manual. Also, some models even provides a sleep mode to let it automatically shut off if it happens to drain during your sleep.

Meanwhile, if you do not use the humidifier very often, it will require fewer refills.

Should You Add some Salt to the Humidifier?

Users assume that adding a bit of salt to the humidifier will create an ocean mist. But in fact, this is a very bad thing to do. It will definitely ruin your humidifier.

To be more specific, the minerals in the salt will clog in the filter of the humidifiers. Besides, salt acts as an electrolyte in the water, speeding up the reaction and increasing the concentration of ions and finally, raising the rate of corrosion of the metal components in the device. In the end, the lifespan of your humidifier will be shortened.

Should You Turn On the Humidifier Day and Night?

No, you should not.

Turning the humidifier 24 hours a day can create a phenomenon of excess humidity. When the humidity level is too high, your air environment will become a wonderful habitat for mold, mildew, and bacteria.

Can You Use Hard Water for Humidifiers?

In fact, you can but it is not advised.

If your humidifier has a mineral cartridge, then it is fine to use hard water. The mineral cartridge, in this case, will help you absorb the mineral content in the water, reducing the risks of allergies and asthmas.

However, if your humidifier does not have a cartridge, you should use distilled water instead.

What You Should Avoid When Using a Humidifier

Should not leave the water in the tank drain to avoid leakage and breaking.

Before refilling the tank, please make sure that all the old water is removed and the tank is carefully cleaned. This is to eliminate the risks of bacteria and mold growth.

Should not use the humidifier continuously. Instead, keep the humidity level at 40 – 60%. You can use a humidity indicator to know the level.

Clean the device regularly, at least once a week.


On hot days, babies may suffer from blisters, eczema, etc., and even worse, chickenpox. Leaving the baby in the room with air conditioners can cause skin dryness, so a humidifier is a better option.

At first, you may think choosing the best humidifiers for baby is a difficult task. But now, after you have read all about the buying guides and the pros and cons of each product, everything seems to be much easier, isn’t it?

And now, let’s make your own decision! Good luck and thanks for reading!
