Remember those times during winter when your baby quickly contacts a cold? It is worrying when they have one. No medications can eradicate the cold at that tender age in such moments. You might want to get the best infant humidifier because it causes immediate relief from almost all cold ailments.

Several products are ranked among the best baby humidifier in the market that you could explore but only with the proper foreknowledge. This article contains baby humidifier reviews and a final verdict on the best nursery humidifier products you should go for.

So briefly, what are humidifiers?

Humidifiers release moisture into the air, which is essential during dry winter. This moisture can help your baby breathe properly and solve dry or irritated skin, chapped lips, sour throat, dry sinuses, stuffy noses, and cough.

There is a high tendency of baby congestion happening during this period, and also, they fall quickly to infections and sicknesses that are often rampant in cold seasons. This shows the need for a humidifier to create the optimal thriving environment and sleeping conditions, allowing your baby to sleep comfortably.

What kind of humidifier is best for baby?

Although there are many other types, the best humidifier for babies in the market today are of 2 types, and they are

  • Warm Mist Humidifier:

This kind of humidifier works by heating water to create warm steam. This slightly warm steam is not at room temperature. Hence warm mist humidifier adds some warmth to the nursery room when used.

Just like we have it in the popular inexpensive Vicks filter-free humidifier, the warm mist humidifier produces humidity like the one found outdoors.

  • Cool mist humidifier:

This kind of humidifier doesn’t add any form of heating to produce mist. Instead, they use an electronic method like ultrasonic vibration  to convert water into vapor or smoke.

Cool mist humidifier is often the most recommended for babies because they are experts in relieving dry air symptoms like dry skin, dehydration, and difficulties in sleeping due to heat.

Henceforth, all humidifiers produce water vapor into the surrounding dry air, but they achieve this purpose differently, and therefore the reasons for their different uses in different circumstances. The table below compares the two major types of humidifiers that are best for babies.

What kind of humidifier is best for baby cough?

Cool mist humidifier is highly productive for throat itching and blockage in the passage of breathing and speaking. Inhaling cool, humid air would go a long way to clear all forms of irritation caused by microbes.

This is because most microbes that cause itchy throat and cough are often inactive in the presence of fresh moisture.

Therefore, since room temperature generally raises the chances of a cough, a cool mist humidifier remains the best option for a baby’s cough.

What kind of humidifier is best for babies with cold and congestion?

Anything congestion or cold has to be from sinus and throat infection. Warm and cool mist humidifiers not only fix congestion causing sickness but also relieve sinus irritation.

As recommended by medical professionals, either warm or cold mist humidifier is the best option for cruel treatment. Hence, you should consider either as the best remedy for congestion.

Unlike the best humidifier for croup, cool mist humidifiers are the most recommended for congestion. This has much to do with safety, just in case a warm mist humidifier could result in burns on your baby. Other functions of cool mist humidifiers are the treatment of flu-like sneezing, croup, and other allergies. It is also a specialist in rehydrating dry and chapped skin that may lead to skin infection.

I must also emphasize that a cool mist humidifier can relieve most of the infant’s allergic reactions. In most cases, you may only need to use the cool mist, and your baby will be back up and healthy.


It is simply because most of the allergic reactions of babies to the environment are often what only need moisty air. Cool mist is usually recommended as a pretreatment before considering the warm mist humidifier. And I must bring to your notice that warm mist never implies hot steam, and the temperature of warm and cold mist is almost the same.

Conclusively, you don’t need just one type of humidifier for your baby. Rather, you need to first use the cool mist humidifier as a pretreatment. Better still, you might want to consider going for the unit with double options i.e., cool and warm mist humidifier.

Here’s how to choose a humidifer for the nursery

On this note, we will only be reviewing and emphasizing more on the best cool mist humidifiers for infants. But before that, let’s look at the things to look out for in the best humidifier before purchasing.

Things to consider when selecting the best humidifier for baby

Ease of maintenance:

Before you purchase a humidifier for your infant at home, you should ensure that it can be easily uncoupled for cleaning. After a while, when using a humidifier, there is a tendency for molds and other organisms to grow in the water container or outlet of the humidifier if it is not cleaned correctly.

This should be avoided at all costs because infants are still young, therefore, have weak antibodies and could easily get infected by the pathogens released by the humidifier. Since you must ensure the humidifier is germ-free at every moment, purchasing an easy-to-clean good humidifier is advisable.

Humidifier mode of dispersing moisture:

Several types of humidifiers exist based on their method of humidification. The cool ultrasonic mist humidifier produces mist utilizing ultrasonic sound vibrations, and the impeller warm mist humidifier uses a fan or disc rotating at a very high speed to create fog. These two humidifiers are known not to disperse materials from their water tanks into the indoor environment.

All in all, it is advisable to go for the humidifier with ultrasonic or evaporative humidification when purchasing for infants.

Why? Some humidifiers tend to release the residue in the tank alongside the water into the air. This may be dangerous for the infant, leading to another form of respiratory ailment.

Presence of a filter:

Humidifiers with filters could keep unwanted pathogens from getting into the air, but if left unclean and without proper maintenance, they could become a source of ill health. Therefore, although it is safer to go for a humidifier with a filter, you must be ready to take proper care of it.

Area of effective coverage:

The size of the room you want the humidifier to operate in would determine the size of the humidifier to purchase. But for a baby’s nursery room, a machine that covers a 100 square foot area may be suitable. Intend using it in a larger room, then you would know what kind of humidifier to purchase and for a larger size.

Built-in diffuser:

For a newborn’s nursery environment, having an inbuilt diffuser in the humidifier ensures that the room retains its moisture and has a pleasant smell that could have health benefits or simply ease congestion. Depending on the product brand and model, you might be required to purchase a specific diffuser.
