What is a baby humidifier and what is it for?

A baby humidifier is an electronic device designed to regulate, control, and maintain the relative humidity inside the house, such as in a baby’s room. These devices work by evaporating the water in their tanks to increase the humidity of the air.

Their main purpose is to keep the relative humidity at the advised levels suitable to a baby’s respiratory system, which is between 40% and 60%.

A humidifier considerably reduces the risk of certain respiratory illnesses as well as improving the general health of a child.

What are the benefits of using a baby humidifier?

In addition to the obvious benefits of the humidifier for babies, such as the prevention of respiratory infections, the use of a humidifier has numerous other benefits for the health of babies and young children. The benefits include the hydration of the eyes and skin in general, as well as promoting natural nasal discharges. Pediatricians highly recommend the use of humidifiers during the winter months.

As you do not want your baby to be cold during winter, it is completely normal to raise the temperature in a house with a heater. Using a heater increases the dryness of the environment and can lead to health issues. However, if you use a humidifier at the same time, this will keep the humidity levels even whilst your baby stays warm.

Patrick S. Pasquariello Jr., MDChildren’s Hospital of Philadelphia
“Choose one that’s the right size for your child’s room. A humidifier that’s too large for the room can create condensation, which could cause bacteria and mold to form. Humidifiers are rated for coverage area in square footage. Measure the room the humidifier would be used in to determine what size device you need.”

What are the risks of not using a baby humidifier?

Dry and cold environments are an ideal environment for viruses to spread and be contracted. With a lack of moisture in the air, a child’s respiratory system may be affected and they may become ill. Thanks to baby humidifiers, you can avoid this and other negative effects for babies as described below:

  • Itching: Itching and irritation in the eyes can be very annoying for a baby. It can also lead to conjunctivitis or other eye infections.
  • Breathing: Dryness in the mucous membranes of the airways and lungs. This can make a baby more vulnerable to infections or viruses.
  • Colds: Worsening of colds and increased symptoms such as coughing or constant runny nose.
  • Skin: Dryness in the skin and related issues such as dry lips or the appearance of eczema.
  • General condition: Breathing difficulties, headaches, and general discomfort.
  • Room atmosphere: A humidifier for babies acts to regulate the humidity of the environment and maintain the recommended levels (between 40% and 60%). Maintaining the humidity level reduces the risk of suffering the illnesses mentioned above.

What types of baby humidifiers are there?

Although there are now many types of baby humidifiers on the market, it is possible to distinguish two main groups: cold steam and hot steam. There is no clear recommendation as to which type is better. There are many pediatricians who recommend cold steam and many other pediatricians who recommend hot steam. The following table gives you some more information about both types so that you can make your own decision:

Function Cold steam Hot steam
Increases room temperature X
Boils water to generate steam X
Fine steam emission X
Lower electricity consumption X
Greater effect against germs and viruses X
Beneficial for the treatment of laryngitis, bronchitis or other diseases X

We can see that both have benefits and drawbacks in different ways. While the cold steam baby humidifiers release fine steam via ultrasonic waves, the hot steam humidifier boils the water. The creation of hot steam can cause the room temperature to rise by 33 to 37 Fahrenheit.

As hot steam humidifiers boil water, this means an increase in electricity consumption in your house. However, as per the table above, it also means greater effectiveness in the elimination of germs and viruses. Cold steam is regularly used in hospitals for the treatment of certain illnesses to great effect.

What precautions should I take when using a baby humidifier?

Any appliance, whether electric or battery-operated, must be extremely safe if it is going to be used in the presence of a baby. To use a baby humidifier properly, you must take into certain considerations to ensure the device works effectively and your child is always kept safe.

  • The first step is to make sure that a baby humidifier is required. If the baby’s room is already humid enough, using one can be counterproductive and a waste of money.
  • Humidifiers can be dangerous devices for children. Ensure they are placed out of reach and try to keep the cables out of sight.
  • Whenever the humidifier is not being used, always unplug it. In addition to safety, this will also increase the life of the device.
  • When the humidifier is in operation in your baby’s room, keep the door open. This will avoid the generation of condensation or mold.
  • Always try to use distilled water in your humidifier. Distilled water produces cleaner steam, as it does not contain lime or minerals.

If you follow these simple tips and precautions, you will not have any problems and the humidifier will provide many benefits to your baby. Avoiding respiratory infections and improving your baby’s quality of life has never been easier and safer with a humidifier. Keep reading if you want to find out more about these fantastic products.

In what situations is it not advisable to use a baby humidifier?

Despite the many advantages of using a baby humidifier, there are certain circumstances in which its use can be counterproductive and even harmful to a baby. Firstly, humidifiers are intended for use in dry environments, so it is important to avoid using them if there is already enough natural moisture in the air.

Although they are beneficial for the treatment of colds or cases of flu, if your baby suffers from allergic rhinitis, COPD (chronic obstructive pulmonary disease) or asthma, a humidifier can make an existing condition worse. If this is the case, we highly recommend that you consult your pediatrician before use.

Where should I place a baby humidifier?

The choice of placement of a baby humidifier is essential to make proper use of it and prevent accidents. The first thing to remember is that the fog or steam should never be emitted directly towards the baby. It is recommended to maintain a distance of at least two meters between your baby and the humidifier.

Ideally, the device should be placed in the center of the room. If this is not possible, the steam should be directed towards the middle, as this will humidify the entire room and not just one corner. If you have purchased a hot steam humidifier, ensure that there is no chance your baby can get close to the device, in order to avoid the risk of burns.

How do you clean a baby humidifier?

Humidifiers expel steam from the water that is held in the reservoir. Therefore, the cleanliness of the appliance and the water is critical for creating clean steam. The maintenance of a humidifier is very simple and can be done at home by following these simple steps:

  • Make sure the humidifier is unplugged before cleaning.
  • Separate the water tank from the base and the filter.
  • For the water tank, fill it with hot water and add a spoonful of bleach to the tank. Leave it to stand for 30 minutes to ensure the elimination of any bacteria.
  • Next, fill a bowl with water and add two cups of white vinegar to clean the filter. Place the filter in the bowl for 30 minutes before removing it.
  • Cleaning the base of the humidifier is also important. You can do this by wiping it down with white vinegar and letting it sit for 30 minutes. After this, wipe it down with a paper towel.
  • The rest of the small parts can be carefully cleaned with soap and water.
  • Carefully dry all parts before reconnecting the appliance.

We recommend following this cleaning routine at least once a week to keep the humidifier in good condition. Remember that these are generic instructions that can be applied to most humidifiers. You must always carefully read the manufacturer’s instructions for cleaning your particular appliance.

Shopping Criteria

Responsible parents never gamble when it comes to buying products for their babies. This is especially relevant when it comes to purchasing a humidifier, as this appliance changes the air that your baby breathes. For this reason, it is advisable to follow specific criteria when purchasing a device of this type. Here are the shopping criteria that we highly recommend you take into consideration when buying a baby humidifier:

  • Type
  • Power
  • Humidistat
  • Capacity
  • Maintenance


Earlier in the guide, we explained that both cool-steam and hot-steam baby humidifiers can provide many advantages. When deciding between one or the other, you must take into account factors such as the needs of your child and the environment in which you are going to use the humidifier.

If you live in an area where it is usually hot, a cold-steam humidifier would be more suitable for you. It will avoid increasing the temperature of the room but it will keep the humidity at the optimal level. If the place you live in is generally cold and dry, a hot-steam humidifier will be much more effective.


The power of the baby humidifier plays a key role in the effectiveness of the humidifier and should not be overlooked. The key aspect to determine is the power required for the size of the room. The larger the room in which the humidifier will be placed, the more power it must use in order to achieve its goal.

To give you an idea, the power needed for a humidifier in a room that is 100 ft² is 75 ml/h. Nowadays, most humidifier manufacturers include an informative table of the power requirements of the product. The following table gives you a general guide of the power required based on the room size.

Room Size Power
100 ft² 75 ml/h
320 ft² 230 ml/h
540 ft² 380 ml/h


The humidistat is a sensor that controls the levels of relative humidity in the environment and can regulate these levels automatically. You must ensure that the baby humidifier you choose has a sensor. This sensor is essential for preventing the humidity in the environment from increasing excessively and becoming counterproductive.

Although most appliances have a humidistat sensor, it is advisable to double-check this. Thanks to the humidistat, the humidifier stops when the humidity in the room has reached the set level (between 40% and 60% relative humidity) and restarts when the humidity drops.


Another key purchasing criterion is the size of the baby humidifier water tank. Although this is not a factor on which the operation of the appliance depends, it is an aspect that makes life easier for parents. The bigger the capacity of the tank, the longer the appliance will be able to run for. As a guide, a water tank capacity of 2 liters will provide you with approximately 8 hours of steam.

Another aspect that must be taken into consideration when it comes to the volume of the tank is the overall size of the appliance. If you are looking for a compact humidifier that does not take up too much space in your baby’s room, you may need to sacrifice some water tank capacity. As always, everything will depend on your specific needs.


Although baby humidifiers have improved significantly in recent years, it is still very important to regularly clean and maintain them. Ensuring the good condition of this appliance is essential for the proper functioning of the device and the health of your baby.

Regularly cleaning the water tank, always using clean water (preferably distilled water) and changing the water frequently is key to avoid the appearance of mold and bacteria. It is highly recommended to buy a humidifier that has a removable filter so that you can easily clean it.


Having a baby humidifier in your child’s bedroom will bring great benefits to their health and overall well-being. These devices are designed to maintain the relative humidity at the recommended levels (between 40% and 60%). This helps to promote the proper functioning of the respiratory system of a baby.

Today, there are high-quality baby humidifiers that use the latest technology. A humidifier can be an excellent solution if your little one has a cold or the flu. It can also be a permanent appliance in their room to help them sleep. You should always stay informed about the types, operation protocols, and maintenance requirements of this type of device to ensure your baby receives all the benefits and is always safe.
