Several safety forward features are also pleasing, including a mold-resistant mist drain tube and an easy-to-clean opening.

This is a durable product, so it weighs a bit more than other models on this list, coming in at 4.5 pounds. Additionally, it features several lights to indicate the humidifier is in use and we found that these lights were on the bright side, particularly overnight. Which can also be found on the best air purifiers for mold, so make sure to look at the model’s features before you purchase.

 #2  SUNLUNA SL-AH001 Humidifier – Honorable Mention

We’re sorry, this product is temporarily out of stock

WHY WE LIKE IT: Extremely quiet unit, producing just 26dB of noise, with a large water tank, 360 degrees of rotation and a maximum output of 300 ml per hour. This is a quiet product that is perfect for bedrooms.

  • Quietest unit at 26dB
  • Large four liter water tank
  • Two year warranty
  • Very bright “on” light
  • Control options are limited
  • Cannot be used with essential oils

The SUNLUNA SL-AH001 Humidifier is a very quiet product, producing just 26dB of noise, making it perfect for an infant’s bedroom. The large water tank operates for around 50 hours of continuous use and the maximum output is 300 ml per hour, which is in line with our top pick. It also comes with a lengthy two-year warranty, which is on the higher end.

Though this is a highly functional unit, the control options are extremely simple, featuring a single knob, and do not allow for much detailed adjustment. Additionally, the “on” light is extremely bright and may need to be covered up with tape when you use it during the night. And if you find this model attractive, you might be interested to learn about our top air purifiers for allergies.

 #3  LEVOIT Dual 100 – Best Essential Oil Diffuser Hybrid

WHY WE LIKE IT: BPA-free design excels at both mist dispersion and oil diffusion, thanks to robust adjustment capabilities, while creating just 28dB of noise while in use. This is a great product for folks looking for a hybrid unit.

  • Excels at diffusing oils
  • Top fill design makes cleaning and refills easy
  • Quiet operation (28dB functionality)
  • The most expensive item on the list
  • The smallest water tank on list at 1.8 liters
  • At 3.5 pounds, on the heavy side

The LEVOIT Dual 100 is a hybrid-designed product that equally excels at the dispersion of water mist and essential oils, thanks to a front panel that allows for multiple adjustments and speed settings. The top-fill design makes simple work out of cleaning and refilling and the unit is also one of the quietest products on this list, creating just 28dB of noise while in use.

While the product does shine with both diffusion and dispersion of humidifying mist, the water tank is the smallest on this list, at just 1.8 liters, so you’ll only get around 10 hours of continuous use, even at the lowest setting. This is also the most expensive product we featured, much like some of the best air purifiers for smoke – they can get pricey very quickly.

 #4  TaoTronics Ultrasonic Humidifier – Best Night Light

We’re sorry, this product is temporarily out of stock

WHY WE LIKE IT: Boasts a unique whale design that will complement the aesthetics of any infant’s bedroom, with a soft night light and a fragrance diffuser, allowing for the use of essential oils. This is a useful product that is also great looking.

The product also contains a fragrance diffuser, which our top two picks lack, making it perfect for using essential oils.

This is a smaller product than the top two picks and, as such, boasts a 2.5-liter water tank, as opposed to four, which can operate for around 25 hours of continuous use. Additionally, the maximum output is just 160 ml per hour, much like some of our best HEPA air purifiers.

 #5  Dreamegg Cool Mist Humidifier – Easiest to Fill & Clean

We’re sorry, this product is temporarily out of stock

WHY WE LIKE IT: Boasts an extremely simple design, with a light form factor, making it easy to refill the water and to clean, with an exterior free of BPA and an added diffuser, for essential oils. This is a no-hassle product that is easy to maintain.

  • Easy to fill and clean
  • BPA free
  • Can be used with essential oils
  • Just 16 hours of continuous use at low setting
  • Nozzle cannot be rotated
  • “On” light is on the bright side

The Dreamegg Cool Mist Humidifier is light, at just over two pounds, and boasts a design that allows for refilling and cleaning from the top, making for effortless maintenance. It also contains a diffuser, which is perfect for essential oils, and the exterior is manufactured without the use of BPA, adding to the product’s safety rating for infants.

The product’s size and weight are a benefit, but the drawback is that the water tank is only two liters large and can only run for 16 hours continuously, even at the lowest setting. Additionally, the nozzle cannot be rotated, requiring manual rotation of the unit itself to reach certain areas of the room, which can be key and a must-have feature in the best air purifiers for asthma. When it comes to babies, there are many products you need to use to keep them healthy and engaged.

  • Great features to price ratio
  • Soft light night changes to 7 colors
  • Can be used with essential oils
  • Unit does not separate for refilling and cleaning
  • Not certified to be BPA free
  • 2.5 liter water tank on smaller side

The Homasy Cool Mist Humidifier boasts a bevy of high-end features while still coming in at a relatively low price point. It contains a diffuser, making it perfect for essential oils in addition to garden variety humidification, and a built-in soft night light that changes to seven different colors with the press of a button. The mist nozzle also rotates 360 degrees, putting this feature in line with our top picks.

The unit is not terribly heavy, at around three pounds, but it does not separate for cleaning or refilling, making those actions somewhat cumbersome. Additionally, though the company says it uses “safe plastics” in the manufacturing process, it is not certified to be BPA-free. Though many best air purifiers for pets are.

 #7  UCAREAIR Cool Mist Humidifier – Lightest Product

WHY WE LIKE IT: Extremely light product, around two pounds, making it easy to clean and refill, with a fully rotatable mist nozzle and a two-month money-back guarantee, along with a one-year replacement warranty. This light humidifier excels at portability and being moved around the home.

  • 360 degrees rotatable nozzle

  • Night light is great, but “on” light is bright
  • 2 liter water tank is small
  • No diffuser for essential oils

The UCAREAIR Cool Mist Humidifier is an extremely light product, coming in at just two pounds, making it ideal for transporting from room to room. The light form factor also assists with cleaning and refilling, as the top easily pops off. The mist nozzle can rotate a full 360 degrees, for humidifying out-of-reach areas of the room, and the system automatically shuts off when out of water.

Though this unit does feature a pleasingly soft night light, the “on” light is fairly bright and may be an issue for nighttime use. Additionally, this is a humidifier only and does not contain a diffuser for essential oils.

How We Decided

To help narrow down to the above top products, we tested out baby humidifiers for mist distance, making sure they would easily service a standard sized living area (320 square feet), and maximum water output, with each product passing a threshold of 150 ml per hour and several pumping out 300 ml per hour.

Additionally, to really discover the best humidifiers on the market, we looked at the tank size, choosing products with large water tanks, at least 1.8 liters and as much as four liters, to ensure a lengthy period of continuous use before needing a refill, as much as 60 hours in our top pick. We also wanted to make sure these products are safe for an infant’s nursery, with no small parts, and, for the most part, are manufactured without the use of controversial ingredients, such as BPA.

Finally, we chose a few products with dual functionalities, acting as both humidifiers and oil diffusers, for the use of therapeutic oils. Several oil variants, such as lavender and dill, are safe for babies. For peace of mind, each product contains at least a one-year warranty, with one product boasting a two-year warranty.

Baby Humidifier Buying Guide

The Most Important Features to Consider

  1. Water Tank Size and Maximum Output
    Humidifiers come in a variety of sizes, with different water tanks. While our top pick will get you 60 hours of continuous use, thanks to its four-liter tank, any of the above products will run through the night, at least ten hours. Additionally, you may want to take a look at the humidifier’s maximum output, which can help humidify large rooms quickly. Our top pick boasts a maximum output of 300 ml per hour but we found that anything in the 100 ml per hour range was suitable for most rooms.
  2. Baby-Friendly
    Some humidifiers boast some baby-friendly functionalities, such as soft, multi-color night lights, which can be a good source of light during nighttime breastfeeding. Additionally, most of the above products are certified to be BPA-free. BPA is an industrial-grade chemical that has been used in the manufacture of products since the 1960s and has been shown to interfere with the production of human hormones.
  3. Oil Diffusion
    The diffusion of essential oils has become quite popular in recent years, as seen in the many humidifiers coming to market that offer dual functionality. Oil diffusion allows for the disbursement of various aromas throughout your room, for therapeutic reasons, such as lavender and mint.
