Best Baby Humidifiers 2020

We pulled together 14 top-rated humidifiers and put them to the test. We ran each for at least a week, all day and all night, and tried out all the features. We tested their ease of use, durability, safety features, noise levels, and capacity. What remained are nearly a dozen of the best humidifiers on the market.

Whether you're combating the winter's dry air or treating coughing, dry and sore throats, colds, croup (we have croup sound files here), stridor, or just a stuffy nose, these humidifiers are perfect. For more details about how to pick a humidifier, and our hands-on review process, see the bottom of this article. Otherwise, here are the results!

Nurseries can get very dry in the winter, especially if you have forced-air heat or like to keep the house on the warmer side. That dry air can exacerbate the symptoms of the common cold and make for an uncomfortable sleeping experience. Turn on the humidifier about an hour before naps or bedtime to prepare the room for your baby or toddler.


Here are the Best Baby Humidifiers of 2020!

1. TaoTronics 6L Cool Mist Humidifier.best humidifiers taotronics 6l cool mist

About $55. TaoTronics consistently blows us away with their quality, features, reliability, and price. This cool-mist humidifier packs a huge 6 liter tank capacity that blows most other humidifiers out of the water (pun intended)! That capacity makes this thing run for nearly 60 hours straight on the lowest setting. Yes, 60 hours! We didn't believe it when we read the listing, but in our testing it lasted 58.5 hours - which was amazing because we used it through 5 straight nights in a row without refilling. Of course, you'll probably run it at something more like medium mist, but even with that setting we got it to run for over 2 nights in a row. Every parent needs one less thing to worry about during the day, and we'll take all the help we can get! In terms of functionality, this is the quietest humidifier we've ever tested - it's truly whisper quiet which makes it really ideal for a nursery. No glug-glug sounds every 30 minutes that are so typical to other humidifiers. No, it doesn't look like an adorable teddy bear or something cute, but you can't argue with this functionality. Refill is easy and just like other humidifiers, and the wide refill opening was a nice touch. No filters to clean, and no risk of steam burns that you get with a warm mist unit. It does have a subtle warm yellow glowing night light on the bottom, but that can be turned off using the button up front. Note also that light turns red when the water level is low, which is a nice feature. Cons? Nothing really. It's not for use with aromas or essential oils, if you're looking for that. Overall, we fell in love with this humidifier and have been using it for several months now; we'll update if anything happens, but we think it's in it for the long haul! Interested?

2. TaoTronics 4L Cool Mist Humidifier.best humidifiers taotronics

About $50. This humidifier offers the overall best features at a truly excellent price. This unit has 3 different speed settings (low, med, high): the low setting is super quiet, and the medium and high settings are still very quiet overall. This humidifier has a much larger tank than the Pure or Anypro, coming in at 4 liters (just over a gallon of water). It is rated for 15 hours of humidifying (at its low setting), which tells us that this unit does an excellent job getting the moisture into the air. How do we know? Well, if it has a bigger tank than most others and is running out after 15 hours, then all that water is going into your nursery! This humidifier also has several advanced features and a nice LED screen. It has a built-in humidity meter to tell you what the current conditions are in the room. It has a sleep timer you can set at night, a rotating nozzle, and a sleek profile. Refilling is a bit more cumbersome than the Pure because it's a bigger tank to fit under the faucet (we used our kitchen sink); but that big 4-liter tank also means it lasts longer without refilling. Cleaning is the same as the other units: clean out the tank and brush off the metal ring. The reliability on this unit is fantastic, and the company is very responsive to any questions or concerns. Other than being a bit harder to fill, there are no other drawbacks to this humidifier other than the higher price tag. Not for use with aromas or essential oils (see #2 for that). Definitely highly recommended as an excellent, high-capacity and high-tech nursery humidifier. Interested? You can check it out here.

3. AnyPro Cool Mist Humidifier.best humidifiers anypro

About $50-60. A good price for one of the best overall humidifiers on the market. This humidifier has a 3.5-liter tank, with a continuous mist control knob allowing you to customize the amount of mist being produced. At its lowest setting, we found that it lasted over 30 hours (!), and at its highest setting, it lasted about 14 hours. That's on par with the Taotronics, but for almost half the price. It's an overall simple humidifier: no filters to change or clean, a single knob controls the intensity of the mist, and there is a single button to turn on a night light. The cool thing about the night light is that it's a subtle colored glow. If you press the button once, it will cycle through a few different colors (red, green, blue, white, yellow, purple), and if you press the button again it will stay on whichever color is currently showing, allowing you to customize the night light glow to your preference. Nice touch! The nozzle on the top spins to adjust where the mist is pointed, and there is also a small aromatherapy essential oil diffuser on the top next to the nozzle. Add a couple drops of your favorite aroma to that diffuser and your room will be smelling great! It also has a sleek, low-profile form factor, and is very quiet. Only a tiny bit of gurgling water every once in a while, otherwise you won't even know it's on. Note that the gurgling sound happens with all cool mist humidifiers. There is a small brush mounted in the base to help keep the stainless mist plate clean. Cons? Well, the nozzle and aromatherapy diffuser on the top tend to fall off when you flip the humidifier over to fill with water. So, you need to pop off at least the aromatherapy diffuser's tiny cover before you bring it to your bathroom or kitchen to fill with water; otherwise, you might end up losing the little cover down the drain like we did! But that really takes a second to pop off when bringing to refill. Other than that, this is a truly excellent humidifier for an awesome price. Highly recommended! Interested?

4. TekJoy Cool Mist Humidifier.best humidifiers tekjoy

About $50. This is an excellent humidifier that offers great bang-for-the-buck, reliable operation, and a great range of features. Its tank is a bit smaller capacity than most of the other humidifiers on this list, coming in at 2.5 liters. In our testing, it was enough capacity to get us through the night at a medium setting (about 10 hours), and enough to get you through about 6-7 hours on the highest setting. Related to that, there are three auto-off timer settings you can use, one for 4 hours, 8 hours, and 12 hours; but realize that it also turns off automatically when it detects that the unit is out of water. Out of the box, the humidifier was easy to assemble, felt durable and high quality, and everything worked very easily. The fill cap was easy to unscrew, the tank was super easy to fill up and fit under our small bathroom sink faucet (which is awesome, by the way, so you don't have to bring it to the kitchen to fill up), and the reservoir was easy to put back onto the unit. Speaking of which, there is a convenient handle on the top of the reservoir which helps a ton. The three cool mist settings were reasonable - the low setting was very light, the medium setting was decent, and the high was not as powerful as some others on this list but still pretty respectable. But let's get to the part our kids loved the most - the lights! This humidifier operates as a night-light with a subtle glow from inside the tank. There are 9 options - off, or one of 8 different colors. The best part is that you can use it as a night-light even when the humidifier itself isn't turned on. Great feature! Some other things we liked were the nozzle that you can position in any direction (but not up/down), the included cleaning brush, SUPER QUIET operation, and apparently very good customer service. We never had to deal with the TekJoy customer service ourselves, but we have heard great things. We've been testing this humidifier for about a month, but we will update after a longer-term test. It does have a couple small limitations worth mentioning. First, there is nowhere to store the brush inside the tank - there is a little slot on the underside of the tank (which is odd), but nothing to hold the brush in, and no groove on the bottom part to keep it in place. Second, it has a limited tank capacity, though for a nursery it's a really nice compromise between capacity and price, and unless you have a 300+ square-foot nursery this will definitely do the job for you. Highly recommended! Interested? You can check it out here.

5. Pure Ultrasonic Cool Mist Humidifier.best humidifiers pure ultrasonic

About $50. A great overall humidifier; in our testing, this humidifier lasted for over 14 hours; this was great because you can turn it on 2-3 hours before bedtime (maybe like 4 pm) and it would go all the way to morning (about 8 am)! Another great feature is that it's very simple to operate: there literally is only one button that controls the power and whether the subtle glowing night light is on or off. Here are some additional features: you can swivel the nozzle around 360-degrees to position it exactly how you'd like. It shuts off automatically when the water level gets low, or if the tank is removed. We also think it is the quietest one on the list - like, really super quiet (you'll be surprised). No annoying filters to clean, no complicated features, and all at a really great price. If you want a humidifier with fancy features, check out the TaoTronics option above, it's also a great humidifier. The only con with this humidifier is that its tank is quite small, at only 1.5-liters capacity. That means that even though it may last an impressive 14 hours, you're actually not getting as much moisture into the air during that time relative to other humidifiers on this list with larger tanks. Interested? You can check out this Pure Humidifier here.

6. Safety 1st Soothing Glow Cool Mist Ultrasonic Humidifier.best humidifiers safety 1st soothing glow

About $40. We got our hands on this humidifier for testing last year and were pretty pleased with its overall performance. It has a smaller capacity than the bigger humidifiers on this list, coming in at about 3 liters (.8 gallons). In our testing, at the lowest setting it lasted for just about 24 hours, which is pretty impressive, though at that setting you could barely see any mist coming out of it at all. Though there is a nice continuous dial to change the mist intensity, it basically still only has a low, medium, and high setting since once you start turning the knob it quickly gets pretty intense. At a more medium setting , it lasted for about 16 hours. So that's probably enough time to turn it on at bedtime and off early in the morning, and be able to do that for 2 nights in a row without refilling the water. At the highest setting, we think it lasted for about 6 hours - we're not really certain because it ran out of water at some point in the middle of the night and we didn't see it until the morning (about 8 hours later). In our testing we found a couple things we really liked. First, when you're refilling the tank there is a carry handle on the bottom, which is helpful. Second, we love the concept of a humidifier with a night light, and this has a nice subtle glow to it that our kids really liked (note that the humidifier has to be on to use the night light option, and if you use it when the tank is empty then you have to deal with the red "empty" light also being on). Third, it was really quiet and has only a very subtle hum to it while operating, and a little bubbling/gurgling sound every hour or so (which they all have). Other than those, it has many of the usual options, like auto shut-off when it runs out of water, no filters to replace, a nozzle that rotates around 360-degrees so you can position it however you'd like, and it's relatively easy to refill. Overall, we like this humidifier and think it is worthy of this spot on our list, especially given the awesome night light feature. After we've used it for several months, we will update this review to reflect its long-term reliability. Interested? You can check out this Safety 1st Soothing Glow Humidifier here.

7. Taotronics Ultrasonic Humidifier.best humidifiers taotronics

About $50. Another great option made by TaoTronics, with a bit smaller capacity than the big one at the top of this list, coming in at 3.5L. That's still quite a large capacity for a cool mist humidifier, and it lasted for about 10 hours on high, and for about 24 hours on low setting. So on the high setting, you're getting over 330 ml of moisture into the air per hour. It uses a continuous knob to adjust from low to high in a highly customizable way. Nowhere near as fancy as the larger TaoTronics, but it's the only one on the list with two nozzles, so you can point one in one direction and the other in a completely different direction, increasing your ability to customize where the humidity goes (like towards two kids' beds in the same room!). Unlike the AnyPro, Pure, and Seneo, this humidifier uses a ceramic filter that helps clean bacteria and other impurities from the water. However, this means you'll need to clean and/or replace the filter with use. Like the others on this list, it automatically shuts off (and shows a red light) when the water level is low. It doesn't work as an essential oil diffuser, in case you're interested in that feature. Note that we tested this unit for 7 months and found that it got a bit louder with time, which was unfortunate. Other than that, this is a great, super quiet, and reliable humidifier that's easy to clean and fill. Just a few drawbacks, including the filter and a bit of noise developing over time. Interested?

8. Honeywell Cool Mist Humidifier.best humidifiers honeywell

About $50. This is a powerhouse humidifier that's been manufactured by Honeywell for several years. We were able to get our hands on one of these units and give it a thorough review last year, and we are happy to report that it is still running strong! This humidifier has a 1-gallon (about 3.8 liters) water capacity, which keeps it running on high for about 9 hours (overnight), or up to about 24 hours on low. That's excellent for running all day to keep a room moist for naps and then bedtime. The operation was whisper quiet especially on the low setting, though there was a gurgling sound every once in a while, as the water moves down from the reservoir. We found the reservoir easy to refill, with a nice wide fill hole, and easy to clean as well. Honeywell markets this as "germ-free" by using ultraviolet light to kill a range of bacteria before it is misted into the room. Unlike most other cool mist humidifiers, this unit does not use a nebulizer. Instead, it uses a moisture wicking filter and blows room air through it to release moisture into the room. It works very well, though we have to be honest that it's a pain to replace these filters every few months (and it gets pricey!). But that filter does do a nice job of trapping minerals in your water, rather than releasing them into your room and causing the white mist on your furniture; so, pros and cons. Another drawback is that the unit is short and wide, so it does take up a lot of space on the top of a dresser or table. Overall, you're getting an excellent, high capacity and reliable humidifier here. If you're willing to put in the work and cost to change the filter every few months, this will be an excellent option for you. And at only about $50-60, it's a great deal!

9. FridaBaby 3-in-1 Humidifier with Diffuser and Nightlight.best humidifiers nusery fridababy diffuser nightlight humidifier

About $50. FridaBaby is a popular baby product company that makes the funny by functional noseFrida nasal aspirator (snot sucker!). They recently came out with this humidifier and we had to get our hands on it for testing. Out of the box, it's most similar to the Safety 1st in terms of size, which means it's relatively small (1.9 liter) capacity but also takes up less space in the nursery. Setting it up was easy, all we had to do was fill the reservoir with water through the somewhat small hole and then place it on the base. When you turn the knob past the OFF position it makes a beep sound and you'll see the mist start. And it's a lot of mist - this humidifier really pushes a lot of humidity out, even on the lowest setting! The dim blue nightlight is optional, meaning you can turn it on or off using a little touch-sensitive button on the front. On the low mist setting, we found that the water would last about 16 hours, and on high it would last about 8 hours. It doesn't sense humidity in the nursery - instead, you set it to a mist level and it will keep that level all night. In addition to the humidifier and nightlight features, it also lets you put aromatherapy grade essential oils into the water tank. Unlike some other humidifiers that use an oil-diffusing pad, this one you place right into the water itself. Which is a little strange because the oils kinda just float on top of the water and don't do much at all. Aside from that oddity, the humidifier and nightlight features work pretty well overall, and we're actually still using it in our bedroom for a long-term test. Relative to some of the top humidifiers, we have a few gripes to mention. First, it beeps when it turns on, and then beeps when it runs out of water - which means that it could wake a sleeping baby. Second, it's a bit noisier than other options with a faint buzzing sound and the drip-glug sound once in a while. Third, the filling hole is small and it can be hard to fit the tank under the faucet in a smaller bathroom sink. And there's the little essential oil issue we already mentioned. Considering all those little gripes, we think you're better off with one of the higher-rated options on this list, especially given the $50 price tag! Interested?

10. Safety 1st 360 Degree Cool Mist Ultrasonic Humidifier.best humidifiers safety 1st

About $30. Here's another good option made by a company with a strong reputation for making high quality baby products at a reasonable price. There are a few things that make this is a great option for your family. First, it is whisper quiet, and even after several weeks of testing it hasn't gotten any louder. When you're looking for a nursery humidifier, the sound level is really important and this makes a great quiet option. Second, it has an awesome dual-direction 360-degree nozzle, so you can orient the cool mist in two directions at the same time. This is super helpful when you're trying to evenly fill a room rather than point it in one direction (and end up with a moist carpet in the morning!). Third, it uses a 2.5 liter tank which is a pretty small size, lasting about 20 hours on a low setting. Speaking of adjustable settings, rather than using discrete low-medium-high settings, this humidifier uses a continuous knob that lets you dial in the perfect setting for your room size and duration of use. We put it on a medium setting and it lasted through the night (from 8pm to 7am) and had about an inch of water remaining in it. Like many of the other humidifiers on this list, it is ultrasonic and doesn't require a filter. It will auto shut-off when it runs out of water, and a light will turn on when you're running low on water. Not too bright to wake up a sleeping baby. So overall we really liked the features and functionality of this humidifier, and definitely suggest checking it out if you're looking for a relatively cheap nursery humidifier that will pack a pretty good punch. Downfalls? Well, relative to other options on this list, its construction isn't quite as high quality. Some of the parts, such as the screw-on fill cap, felt a little flimsy and brittle; some customers have complained on Amazon that it broke when trying to remove it. Never happened to us, but like with all humidifiers you need to be really careful about how much you tighten that fill cap - you want to hand-tighten it until it's barely snug. If you over-tighten it, the expansion of the plastic will make it a total bear to remove. So be careful with that. A second thing is that cleaning is pretty difficult because the fill cap is so small. You will only likely need to clean it about once a month, especially if you don't let water sit in it for several days. But when it is time for cleaning, it's not as easy as most of the other options. With those negatives being said, it's important to realize that this is a 2.5-liter humidifier that can be purchased for under about 30 bucks. And that's a sweet deal and makes it worthy of this spot on our annual list! We'll update after several months of use.

11. Vornadobaby Huey Evaporative Humidifier.best humidifiers vornadobaby

About $100, and definitely one of the better humidifiers on the market for a few reasons. Though the tank is exceedingly small at about .25 gallons of water, it is super easy to refill and clean. It has a convenient little handle that you use to pull the tank out (about the size of a water bottle) and refill. Instead of having just low and high settings for fan speed, it also has humidity adjustment so you can set the desired humidity (we used 55%) and it will cycle on and off as needed. Or you can tell it to be on continuously. This humidifier uses a "wick" filter that you'll need to replace every few months, at the cost of about $7 each. Just like any other humidifier, you'll need to clean the tank frequently. Drawbacks? Well, the water tank is really small so you're not getting a ton of moisture into the air overnight. It's also not super quiet like the ultrasonic options on the list. In fact, it was the noisiest one we tested.

Details and Conclusions:

During the fall and winter months, the cold strips the humidity from the air, and heating your house makes it even worse, especially if you have forced air heat blowing into your baby's room. All that dry air makes symptoms worse for your baby, and makes it take much longer to recover.

The nighttime is when your baby's immune system will get a chance to fight viruses and clear up symptoms. This is the perfect time to fill up and turn on a powerful and safe humidifier to add some moisture back into the air, soothe dry throats and coughs, and help your baby fight viruses. So, what should you look for in a humidifier?

Cool versus warm mist humidifiers for babies: Doctors recommend cool mist humidifiers. There are two types of humidifiers - cool and warm mist. Both add moisture to the air, but warm mist humidifiers are more dangerous. Both cool and warm mist humidifiers add moisture to the air, but they do so differently. Cool mist humidifiers force water to dissipate into your room without using heat. Warm mist will heat the water and then send it into the room in the form of steam. Though you might think that warm mist would be better because it will keep your baby warm and cozy at night, cool and warm mists are exactly as effective as each other for helping coughing and congestion (if you don't believe us, read about it at the Mayo Clinic). But warm mist humidifiers are dangerous for use in a baby's room: they can spill hot water, and burn your baby if they get too close to the steam. They are also more expensive than cool mist because they have the added heating element, and they are much noisier at night with the bubbling and hissing involved in heating the water.

Noise levels vary across models. Some humidifiers run low-quality fans and fan motors that introduce a loud drone into your baby's room. The better-quality humidifiers use quieter fans, or even better, no fan at all and instead rely on ultrasonic humidification. Cool mist are also quieter than warm mist because there is no background bubbling and hissing noise from boiling the water inside the unit. The humidifiers we recommend above are some of the quietest we could find.

Germs and bacteria cause problems. If your baby is sick, the last thing you want to do is pump more germs into their room. All humidifiers, even the ultrasonic ones, and both the warm and cool ones, can build up mold and bacteria in their tanks and other components. If you're considering using a humidifier in your baby's room you must be sure to clean it regularly (like every few days)! A solution of 90% water and 10% bleach is perfect, just make sure you rinse well after cleaning. Also be careful where you point the humidifier in your baby's nursery: try to avoid pointing it directly at your crib (see our reviews of baby cribs here) or glider (see our reviews of nursery gliders here), since that might cause dampness, mildew and mold to form on the furniture.
