Best Humidifier for Baby: Buying Guide and Our Top 10 Picks

Humidifiers are an invaluable device for your home that can alter your quality of life for the better. Used mainly during the winter months, a humidifier adds moisture to the cold, dry air that is present during this time of year. It is this moisture that helps to alleviate allergies, colds, flu, body aches and pains, skin conditions, and various respiratory illnesses. With regular use of a humidifier you will sleep better, you won’t be incessantly coughing, and your overall stress levels will be reduced. Humidifiers come in a wide range of looks and sizes, with the higher end models having helpful bells and whistles thrown in. There are also differences in the technology that humidifiers use to moisten the air.

With so many options available, how do you know which is the best one to pick up on your next shopping trip? We try to alleviate the confusion for you, and present to you our top 10 picks when looking for a new humidifier for your home.

Why would you need a humidifier for your baby?

Few things in life change your perspective and re-arrange your priorities quite like having a child does, and once that baby is born there is little you wouldn’t do to keep it happy and safe. Most children are walking germ factories for the first few years of their life as their bodies acclimate to various bacteria and viruses. Humidifiers will help keep baby in the healthiest state possible, so they can easily fight off infections and allergens.

Our homes contain airborne particles that can be harmful to certain individuals, and the delicate constitution of a baby is no exception. The winter months, while visually stunning, bring some of the worst air quality into people’s homes. The dry air causes our skin to itch, flake, and crack. It creates an environment for the flu and cold to thrive, being passed from person to person, indiscriminately. Our nasal passages become constricted and dried out, which makes catching a cold through our mucus membranes much easier. Our bodies try to fight this off by creating an overabundance of mucus, leading to a lot of nose-blowing and more nasal irritation.

Adding moisture to the air will lessen these effects as a balanced level of humidity keeps your nasal passages lubricated and working properly. Too little humidity, you get sick. Too much, you get sick. Humidifiers with a gauge on them are excellent choices so your room is constantly monitored and stabilized.

It is safe to say that babies require an even higher level of care than the average adult when it comes to their health. Humidifiers will keep them in the proper environment to help prevent illness and promote healthy sleep, which as we all know, is hard to come by with newborns.

Things to Consider Before Buying

As with most products, there is no be-all end-all when it comes to humidifiers. There are many factors to take into consideration to make sure you are getting the proper device tailored to your specific needs. Here are a few things you should always be on the lookout for when you are making your selection.


Some people can sleep through anything. Others wake up very easily. Humidifiers can be mechanically different from each other, which can affect the amount of noise they produce.

If you are someone who needs total silence to fall asleep, go with an ultrasonic humidifier. They use high-frequency sound vibrations to produce mist. They are affordable, portable, and whisper-quiet, making them a very popular option.

A more expensive but effective humidifier to cover a larger area of your home is a central humidifier, which attaches to your hot air ducts and cold air return. It makes circulating moisture very simple, but also makes it as loud as when your central heating kicks in. If you can sleep through that noise, this might be a perfect option for you.

Impeller humidifiers are a third option. They work by using a disc to spin water at a diffuser. The diffuser breaks up the water into tiny drops that get dispersed into the air. If that sounds like it might be a bit noisy, you are correct. While they are effective humidifiers, they do have a reputation for being a bit too loud for most consumers.

Evaporative wick humidifiers are another popular option. They use a wick to soak up water, and then a fan disperses the moisture from the wick. They operate well and are very safe to use, but they do make a bit more noise than their ultrasonic counterparts.

While all the humidifiers above emit a cool mist, vaporizer humidifiers emit warm mist by heating up the water to an ungodly temperature, essentially turning the liquid to vapor. While they are a quiet option, a lot of people are put off by the high temperatures needed to create the vapor.


As with any electric device, safe operation is of the utmost importance. As humidifiers use water in conjunction with an electrical current, you should always follow the operation manual to ensure you are using your unit safely. If you are using a humidifier with a fan in it, you want to make sure that there are no obstructions preventing it from spinning, or worse, flinging something across the room. Vaporizer humidifiers seem to be the ones that you have to be extra cautious with. While extremely effective with their warm mist, the unit itself can heat up, and the water can scald if knocked over. It is for these reasons vaporizer humidifiers are recommended to be placed out of reach to minimize the risk of accident.


Cleaning your humidifier is something that should be done as often as the manufacturer recommends. Most cold mist humidifiers need cleaning after every few uses to keep bacteria from forming and being dispersed during use. This can usually be done with soap and warm water.

If you are using it frequently, evaporator wick humidifiers require changing the wick every 4-6 weeks. In the meantime, you can soak the wick once a week to remove any hard water deposits that can build up and dry it out. Soaking it in a warm water and vinegar solution for 20 minutes will remove a lot of the debris.

Warm mist vaporizers should be cleaned after every use, as the heat they generate will leave hard water deposits on the base of the unit. These deposits will not only leave stains, but will also creep into the water supply and be dispersed with the mist.

Regular maintenance of your humidifier will provide a lot more use, keep your air clean, and save you money in the long run.


Humidifiers come in a variety of sizes depending on where you are using them. If you have a normal-sized bedroom, a small or medium unit usually does the trick, with larger rooms demanding a larger humidifier. There are even portable travel humidifiers you can fit in your luggage for your next trip. Having said that, as all our needs are different, it is usually recommended to go a size up to make sure you have more than enough coverage for the room you want to use it in.


Most humidifiers are pretty affordable, with the majority of models ranging anywhere from $40 to $100. The two main ongoing costs you need to take into account are your electricity bill, and the cost of replacing the filter if you are going with a model like a wick humidifier. As warm mist vaporizers require the water to be boiled, they use a lot more electricity than the cool mist humidifiers which more or less just need to operate a fan. From a cost perspective, cool mist humidifiers will be cheaper in the long run.
