Should I Use a Cool Mist Humidifier for Baby?

Many families have used humidifiers during the dry season to bring in the fresh air. But if you choose the wrong good machine, it will be harmful. This short article we shares some ways to choose the best type of humidifier for your family.


What is a humidifier?

A type of moisture balance machine to help maximize the living environment, including air purification function, blowing steam to create a sense of clean and cool.

The effect of a humidifier

If the air around you is too dry for your skin and nose to feel uncomfortable, turn on the humidifier to enjoy the following benefits.

The humidifier helps prevent influenza

One study suggests that a humidifier may reduce the risk of flu. After putting the influenza virus in the air, the researchers found that the air with humidity above 40% stopped the virus from working quickly. This will make the virus less likely to spread, thereby helping you prevent the flu.

A humidifier helps eliminate phlegm

Dry air can cause a dry cough without pushing the mucus out of your neck out. You can add moisture to the air to moisten the respiratory system, thereby pushing the sputum out more easily when coughing.

A humidifier helps reduce snoring

Increased humidity in the air can also help reduce snoring during sleep. If the air is dry, your airways usually aren’t moist enough and this can make snoring worse. So you can use an air humidifier at night to reduce snoring.

Humidifier moisturizes skin and hair

Skin, lips, and hair often become dry and more vulnerable when it’s cold. Cold air will make the skin dry, itchy, and flaky. You can add moisture to the indoor air to improve dry and chapped skin.

The humidifier reduces allergies and asthma

Using a humidifier properly can also help you reduce allergy and asthma symptoms very well. So, you can consider using this device if your sinuses or airways are dry.

Side effects of a humidifier include:

• A humidifier may contain bacteria: A humidifier turns water into moisture in the air you breathe. If the amount of water in the device is dirty, the diffuser moisture will become dirty. Also, the dark and humid storage compartments should be an environment where bacteria can easily accumulate. However, you can clean it regularly to prevent this risk.

You should always clean the humidifier thoroughly according to the manufacturer’s instructions and change the water in the machine regularly. If the humidifier has a filter, change the filter regularly.

• A humidifier diffuses too much steam: While the air is good, too much moisture can make it hard to breathe and make allergy symptoms worse. Common allergens such as mites, dust, and mold will thrive in moist environments. According to the US Environmental Protection Agency ( EPA ), indoor humidity should only be between 30 and 50%. Humidity above 60% is too high.

You can buy an extra hygrometer to check if the indoor humidity is within the ideal range. Alternatively, you can also buy a humidifier with a built-in hygrometer for more convenience.

• Use unclean water in a humidifier: You should only use pure water or distilled water in a humidifier because unfiltered tap water can contain lots of minerals. Minerals from tap water can accumulate in a humidifier, causing them to wear out quickly. Besides, the device can also disperse these minerals into the air or cause minerals to settle into dust in the house and affect your health.

Some other risks associated with using an air humidifier include steam from machine and mold that accumulates in humid places on walls and ceilings.

Classification of humidifiers

We often classify into usage, classified by brand, … but I choose to classify products by the principle of operation of the machine.

Thermal-operated humidifier: Use heat to heat the water until the temperature evaporates, then steam will be released through the internal parts of the machine. This heat will help keep the humidity in the air maintained at a stable level for users to safely.

Ultrasonic humidifier: It produces steam with an electromagnetic wave system that vibrates at high frequencies and creates lithium particles that quickly enter the air like mist. This unit has the advantage of being able to save more energy than heat-operated machines but is considered to be unsafe for airways.

Experience to buy the best humidifier

There are many brands with diverse designs and prices besides many different device selection criteria of the user. shares some experiences when choosing based on the criteria below so you can choose the best type of nebulizer.

Criteria to choose a humidifier

Select the type of machine according to the object to use

According to the user, there are 2 types of humidifiers:

Machines with low capacity: Mainly users are students, individuals, households, and rooms using air-conditioners with a not too large area. This is the most common and used machine.

High-capacity machines: Used for workshops, factories, restaurants, cafes, or beer bars. This type is usually large capacity, high cost but creates moisture in a large area. However, I limited in this article and will focus on the most popular humidifier today.

Select the way the machine works

Based on how it works, there are two common types of machines on the market: ultrasonic humidifiers and thermal humidifiers.

Ultrasonic humidifier

It can be understood that the machine uses ultrasound to convert water into mist form and blow out through the ventilation system to bring moisture to every corner of the room. The steam is blown out very cool so it is not dangerous to users.


  • Energy saving
  • Very low noise, no noise when operating
  • The body is usually made of ABS plastic: very hard and durable.

Cons: Easily broken, water bottle stopper sometimes not tight

Thermal humidifier

The machine uses temperature to vaporize steam into the air.


  • There are diverse models
  • Easy to use, easy to disassemble and clean
  • There is an automatic shutdown mode to avoid incidents.


  • Slightly energy consuming
  • Less suitable for families with young children because the device uses heat.

Choose machines by brand, model

Currently, there are many brands of this humidifier, not to mention products of unknown origin. So when choosing a nebulizer, which part you should care about the brand.

This helps you reduce the likelihood of buying poor quality goods. Some popular brands such as Philiger, Fatz, Magic Home, Home Easy, Saiko, Fujioka … You will easily buy a humidifier with prices from several hundred to several million.

With the above brands, most of them have a variety of colors, blue red purple yellow … full sizes, styles, and shapes such as square, frog, flower pattern, fruit … extremely eye-catching.

Choose by room size

Choosing a humidifier by room size is because it affects the moisture diffusion capacity of the machine. Calculate the room area to choose the machine with compatible water tank volume.

Large rooms with small appliances will not provide enough moisture, because home humidifiers can work well in rooms under 50m². Conversely, the humidity is too large, the phenomenon of condensation will appear and allow bacteria and molds to multiply, grow, causing unwanted effects on the health of everyone in the family.

Types of humidifiers

The air humidifier is very diverse in models and each has a different way of operating.

• Nebulizer (humidifier): A humidifier uses a fan to blow steam through a filter and diffuse into the air. The device, while affordable, can spread too much moisture into the air, increasing the likelihood of developing mold that affects people with asthma.

• Impeller humidifier: The impeller humidifier works with the help of rotating discs that run at high speed to diffuse the steam. This is the most kid-friendly device because it creates cool moisture, avoiding the risk of burns to the baby. However, the rotor humidifier can cause breathing difficulties for people with allergies and asthma if overused.

• Steam humidifier: A steam humidifier uses electricity to heat water to create steam. The steam is then cooled before diffusing into the air. Due to this mechanism of operation, a humidifier can cause burns and is not safe for children.

• Ultrasonic humidifier: The ultrasonic humidifier generates cool moisture by ultrasonic vibrations. It also allows you to adjust the temperature of the steam if desired. This may be an appropriate option if your home has children.

How to use a humidifier

Once you’ve chosen your desired air humidifier, follow these steps to start using it:

Remove and rinse the water tank to remove dirt before use.

Pour pure water or distilled water into the water tank of the machine. Usually, on the water tank, number lines are telling you how much water you should pour. Fill this amount with the right amount of water.
