3 Best Baby Humidifiers on the Market with Experts’ Buying Guide

So, you are considering buying a baby humidifier for your little one’s nursery room. Good for you (and for your baby)! Does this mean there is no need to convince you that you need a humidifier?

Considering that most of your brain cells already died in agony thanks to the countless sleepless nights new parenthood so strikingly presents to us, I still think you might need a little convincing. Here it goes.

5 reasons you need a baby humidifier:

1. It creates optimal breathing conditions for your baby, aka as no stuffy noses and frequent sore throats. Bye-bye, nose pump, welcome nicely humidified air!

2. It immensely helps with baby skin problems like dry eyes, skin irritations, chapped lips, and the like. No more itchy skin and red patches! An added bonus is that your skin gets moisturized as well, which is great as we both know you hardly have the time to shower, let alone use a skin moisturizer.

3. Most models emit white noise. You can go on and uninstall that white noise app you just downloaded on your phone – a humidifier will do the same job without killing your phone battery. The standard (evaporative) humidifiers emit louder noise while the ultrasonic ones emit an almost inaudible calming white noise helping your baby relax and get (the hell back) to sleep.

4. Unlike over the counter cold medicines, humidifiers have no side effects. Cool, huh?

5. All in all, baby humidifiers allegedly help babies sleep (better) through the night. What more can you want from life as a parent? Well, a daily shower would be nice but let’s not be greedy.

4 features to look for in your baby’s humidifier:

1. Operation (noise) – if you have a newborn that has difficulties falling asleep or your baby is experiencing a sleep regression, perhaps a humidifier emitting calming white noise is the better choice for you. If your child is older, you may opt for a completely noiseless one.

2. Auto shut off – that’s an essential feature of any reputable humidifier as it prevents the appliance from burning out if all the water in its tank has evaporated. Oh, and most models even turn themselves off when they reach the desired level of humidity and/or when the set time is up. Nice job, humidifiers, nice job.

3. Maintenance – the easier it is to clean and refill your baby’s humidifier, the better. Hint: baby humidifiers that don’t feature a removable water tank can be a real pain in the *ss. Just saying. Oh, wait, there’s another one! Hint 2: If you use an ultrasonic humidifier (which we highly recommend for babies), you won’t have to buy replacement filters.

4. Antibacterial features – some baby humidifiers have these extra cool antibacterial features like fancy filters, cartridges, ultraviolet lights and the like that eliminate (or inhibit the growth of) bacteria, mold, and mildew.

Your questions answered:

Should I choose cool mist or warm mist?

Basically, there are two types of mist humidifiers depending on the temperature of the mist they emit: there are cool mist humidifiers and warm mist humidifiers. If you are going to use the humidifier for a nursery room, we strongly recommend using a cool mist one.

The reason behind this is that hot water (or steam) can easily burn your baby or toddler if they accidentally get too close to it. Besides, it’s meaningless to use a warm mist humidifier as it’s no more effective in humidifying the air. What’s more, by the time the mist reaches your child, it’s more or less the same temperature (regardless of which type you’ve chosen).

Why ultrasonic?

It’s a brilliantly simple reason: ultrasonic means no need to change filters. And that’s one less task on mommy’s (endless) to-do list. Hurray!

Besides, non-filter baby humidifiers use a physical process (ultrasonic waves) to purify water while filter humidifiers rely on chemical processes for this.

Ultrasonic baby humidifiers are the most modern and the most recommended humidifiers for babies. What’s more, they don’t use a fan to disperse the mist, which makes them much quieter (compared to the common evaporative humidifiers).

And last but not least, ultrasonic baby humidifiers can easily save you enough money for a vacation in Bora Bora by buying replacement filters. Well, not exactly, but you get the point.

Why do I have to clean the damn thing?

I hate to break it to you, but baby humidifiers, unlike baby swings, are not one of those set-and-forget baby gear. Have in mind that mold (and its best friends – bacteria and mildew) needs only about 48 hours to start partying on a damp surface. This means that you should carefully follow all cleaning instructions that come together with your new baby humidifier.

What water should I put in?

Most humidifiers work just fine with tap water, but, depending on the area you live in, your tap water may have miniature mineral particles in it (the so-called “hard water”). If this is the case with your tap water, it is best to fill your baby’s humidifier with distilled water and spare yourself the dispersing of minerals in your baby’s nursery. In any case, if you want your humidifier to work at optimal conditions, it is recommended that you use distilled water. Bugger.

Final Verdict:

Choosing the right baby humidifier for the nursery room of your baby is not difficult. Just follow our advice above and pick the one that best suits your budget, style, and needs. And do not forget to take all precautionary measures (better-known as RTFM).
