Choosing a Humidifier for Your Baby

Before buying a humidifier, it’s a good idea to learn about their pros and cons, what they can be used for and the different kinds of humidifier on offer.

Here are answers to some of the most frequently asked questions about humidifiers. If you have a question that isn’t covered here, please leave a comment below.

Why get a humidifier?

Babies often suffer from dry and sensitive skin and humidifiers act as natural moisture agents to keep the air in a room from being too dry.

Using a humidifier in your child’s room is becoming more and more prevalent as the benefits outweigh any negatives.

A humidifier can add between 30-40% humidity back into the air in your home, bearing in mind that between 30-60% humidity is advised in a home.

Using a humidifier will stop the effects that dry air has on your baby while they sleep. Dry air can cause major irritation throughout the body and is not conducive to a good sleep condition.

Having one of these devices in your baby’s room can help to prevent a variety of health conditions:

  • Dry nose and respiratory problems
  • Dry skin
  • Chapped lips
  • Acne
  • Bloody nose
  • Sinusitis
  • Allergies
  • Asthma
  • Cold/Flu*

*A humidifier can really help your baby during cold and flu season. The moisture released into the air can help to clear mucus, allowing the secretions to loosen meaning the baby will sneeze or be able to swallow the mucus. Great for baby and great for a tired mummy or daddy.

Humidifiers can increase comfort during cold winter months, or dry summer periods, as they help prevent dry skin, throat or eyes, cracked lips, bloody noses and sensitive sinuses.

A humidifier will also help to prevent illness.

The tiny hairs in your nose filter out bacteria and viruses and are more effective when they are kept slightly moist. In case you have a cold, a humidifier tends to ease the symptoms.

Wooden furniture, flooring, musical instruments and wallpaper are conserved better with a humidifier as it keeps the humidity level at a constant, moderate level of around 40% to 50%. To measure humidity and check it’s at the right level, you can use a hygrometer.

What are the disadvantages of humidifiers?

If your humidifier is not clean, it may have an adverse effect on comfort and health, as bacterial and mould builds up inside machine and spreads through the room when the humidifier is on. To avoid this, make sure to clean your humidifier regularly with bleach.

A humidifier could increase the humidity level by too much, causing mould build up and dust mites. Invest in a hygrometer and make sure humidity does not exceed 50%.

What should I look for in a humidifier?

Firstly, before you look for a humidifier, make sure your child’s room actually need it. In winter, it is more likely that you might need a humidifier as moisture levels in the home can drop to 10% and below due to the drying effect of central heating.

As mentioned above in our safety section, you are best off looking for a cool mist humidifier for a child’s bedroom as these are the safest option and they also make for the more comfortable environment for sleeping.

Some prefer warm mist due to the heating process that kills germs and viruses, but it is best to consult your trusted GP for advice. If you do opt for a warm mist humidifier, then be sure to keep it away from your child’s reach to avoid burning.

It may sound silly, but if a humidifier makes a gentle hum as it works, this can be great for sending your baby or toddler into the land of nod. So if your child is prone to falling asleep when you’re vaccing or drying your hair, there is a chance a low hum is something you should look for!

How much do humidifiers cost?

The variation in price for humidifiers is quite large; it all depends on the type you want to purchase and the capacity of the machine.

You can get smaller capacity ultrasonic diffusers for less than £10, whereas larger capacity humidifiers can stretch to £100 or more.

Do humidifiers help with allergies or asthma?

Humidifiers can help with allergies and asthma, but it is important to keep in mind a few points.

When the humidity level is too low, your sinuses and respiratory system are likely to be more irritable and allergy symptoms and asthma may get worse. A humidifier may help ease these symptoms by increasing humidity to a comfortable level.

If humidity is too high (anything above 50% humidity), dust mites will increase in numbers, as they tend to thrive in humid and warm environments. As many people are allergic to dust mites, increasing humidity too much may worsen allergy symptoms.

In case of serious allergies or asthma, make sure to speak to your physician before buying a humidifier in order to help you select the one that best fits your needs.

Are humidifiers safe?

Some humidifiers use heat to create the steam or mist released into the air, which can of course be dangerous in a home with babies, small children and pets. A cool mist humidifier is the best option for a family home.

Having a humidifier in use in your baby’s bedroom is great, but you must clean the humidifier regularly or you may find that you are just blowing dust all around.

Also, if you use a humidifier in a home that already has a high humidity level, mould or mildew can build up.

This can be very harmful and must be cleaned with a very diluted bleach solution with distilled water to ensure the vapour released is clean.

Vapourisers heat up the water in their system, meaning the water is sterilised, unlike humidifiers.

If you use medicinal vapours in your machine, make sure to clean it out once there is no longer a need for the medicine.

Keep your humidifier unplugged and out of reach of children when not in use.

Do humidifiers warm rooms up?

Warm mist humidifiers can slightly warm up rooms, but will not be able to replace your heater.

As humidity increases in a room, however, it can feel hotter as our skin sheds heat less efficiently in a humid environment.

What are the differences between warm and cool mist humidifiers?

Warm mist humidifiers boil water and emit hot steam, whereas cool mist humidifiers such as these reviewed here emit a cold mist created by ultrasonic waves.

Cool mist humidifiers tend to be quieter, so are often recommended to use in the bedroom, especially for light sleepers.

Cool mist humidifiers tend to use slightly less electricity than warm mist humidifiers, so may be cheaper to run.

Both have different mechanisms to kill or filter out bacteria and viruses, so are safe to use as long as precautions are observed.

Warm mist humidifiers can cause burns in case they are knocked over and the water is spilled, or if anyone puts a body part in the emitted steam. For this reason, it is best not to use them when children or pets are around.


Types of humidifiers

There are multiple types of humidifier on the market, some more affordable than others and some more suited for use in a baby’s room.

You would most likely want to opt for a cool mist humidifier for your child’s room as they create a better sleeping environment than steam humidifiers, which make for a less than comfortable, hot sleep.

Some people prefer the effects of a warm mist humidifier as they are good for cleansing water, killing germs and viruses and making it easier for the baby to breathe.

However, steam humidifiers can cause paint or wallpaper to peel if the machine is continually used in the same spot, so this may want to be something to consider when choosing!

Here are the main types of humidifier you may come to choose from for your own home: 

1. Central Humidifiers

Cost: High

This type of humidifier is usually built into a home’s heating/air conditioning unit and can be very expensive to install.

It is not such a great option for controlling humidity in specific rooms as it is just a general household humidifier.

2. Evaporative Humidifiers

Price range: Medium to High

Evaporative humidifiers blow moisture through a dampened filter using fans. These are good for use in one room at a time so you can target a specific area of your home i.e. great for use in bedrooms. They can be affordable but are still not the best choice for your baby’s room.

3. Impeller Humidifiers

Price range: Low to Medium (depending upon manufacturer)

Using high speed rotating discs an impeller humidifier emits cool mist which is great for kids and pets. The cool air makes this the perfect option for a baby bedroom!

4. Ultrasonic Humidifier

Price range: Low to High

An ultrasonic humidifier works using a ceramic diaphragm that vibrates quickly and smoothly to produce the cool mist which is expelled silently by tiny fans. These are another great option for a baby’s bedroom due to their practical and quiet emission of moisture.

5. Steam Vapourisers

Price range: Low

This type of humidifier is known as a vapouriser and is powered using electricity to heat the water before releasing it into the air.

A few models of vapourisers have the option of hot or cold mist which is great for a baby. Vapourisers can be enhanced by adding medicinal vapours to aid your child during cold/flu season and through other ailments.

Humidifiers vs. Vapourisers

When it comes to choosing between these two machines, you must consider what you want.

A humidifier is more general in its health benefit, helping to prevent issues with dry skin, allergies and irritations, whereas a vapouriser can be used in the treatment of a cough or cold and medicine can be mixed with the water.
