How to Pick the Best Humidifier for Baby For Your Needs

The first few months of a baby’s life are arguably the most important. It’s why you must use only the best humidifier for the safety of your child.

A humidifier is essential because it helps maintain a healthy humidity level in your child’s room. It alleviates coughs and colds by thinning out the mucus and soothing the dryness of the cough.

Here are some things you need to consider when buying the best humidifier for your baby.

Cold or Hot Humidifier

Humidifiers expel either cold or warm mist and are sometimes referred to as a vaporizer. Both soothe cough and colds, but warm vaporizers have the added benefit of heat to kill off unwanted bacteria.

Warm humidifiers are also generally more dangerous if a child reaches the unit, as it can cause severe burns.

Personally, we always go with a cool-mist humidifier. It’s safer and does the job just as well.

Automatic Moisture Control

Lack of humidity is terrible, but excess is worse. It can lead to dangerous bacteria and mold growth in the room, too.

Too much humidity can make you sick, according to the Mayo Clinic—the opposite of what a humidifier is meant to achieve.

What’s the best way to avoid this?

Get a humidifier that can detect the room’s humidity and regulate it automatically. You’ll be assured of healthy levels and free of worry.

Coverage Area

Humidifiers vary considerably based on the area of the room. Make sure that the humidifier you buy is capable of adjusting the humidity of your size room.

The feature is measured in square feet, so it’s a simple matter of measuring the area of your baby’s room and selecting the correct humidifier.

A good rule of thumb is to go for a product that covers 100 square feet at least—it is about the size of an average nursery.


Diffusers allow you to place aromatherapy oils inside the portal to scent a room naturally.

A looming question remains: is aromatherapy diffusion safe for your baby? It’s a resounding yes, according to doctors.

You have to be careful, though. Not all essential oils are safe for you and your baby. The secret is to do your research, read the fine print, and ask your doctor before trying it at home.

If you’re going for a diffuser, make sure the essential oil is compatible with the unit you’re considering. When in doubt, buy it from the same manufacturer.
