1. Levoit LV600HH – Best Overall Ultrasonic Humidifier

Levoit LV600HH

  • Power: 120V, 60Hz
  • Coverage Area: 753 sq. ft.
  • Tank Capacity: 1.5 gallons
  • Runtime: 36 hours

With more extensive coverage of up to 753 square feet and a relatively longer runtime of up to 36 hours, the Levoit LV600HH is our best overall ultrasonic humidifier.

Another thing that gives it an edge over most others on our list is that it has a setting that allows you to choose whether to use warm or cool mist. Cool mist helps keep your skin hydrated, while the warm will ensure the water is free of bacteria.

Because this machine has built-in sensors, it will sense the humidity levels and adjust automatically to ensure they are always optimal. And with the convenient remote control, the operation will be a breeze.

There is no carry handle on this machine, which can make it a little hard to grasp and carry. But, the good news is that it is relatively compact and not that heavy, and so it should be easy to move around.

Pros:

  • Wider coverage
  • Has both warm and cool mist
  • Adjusts humidity automatically
  • Convenient remote control
  • Relatively longer run time

Cons:

  • No carry handle

2. Crane EE-5301W – Best Budget Ultrasonic Humidifier

  • Power: 120V, 60Hz
  • Coverage Area: 500 sq. ft.
  • Tank Capacity: 1 gallon
  • Runtime: 24 hours

Crane EE-5301W is the perfect product for those that are looking for not only the best small ultrasonic humidifier but also something more affordable as it is the cheapest model on our list.

But the lower price tag is not a reflection of inferior quality or smaller capacity as this model is still well-built and will cover up to 500 square feet, while also providing continuous operation of up to 24 hours.

With its 360-degree mist lid that is also adjustable, it will diffuse the mist in all directions to ensure the entire room is covered. The tank is easy to remove and fits perfectly under the sink for easy refills while the adjustable speed settings provide easy customization.

Essential oil capability would have been excellent to allow you to diffuse your favorite essential oils, but for this budget model, its absence is still not a deal-breaker.

Pros:

  • Relatively more affordable
  • Dispenses mist in all direction
  • Tank is easy to remove and refill
  • Speed settings can be adjusted

Cons:

  • Not essential oil capable

3. Vicks V4600 – Best Ultrasonic Humidifier Brand

  • Tank Capacity: 1.2 gallon
  • Runtime: 30 hours

Vicks is a top humidifier brand despite being more famous for its cough and congestion relief products. Over the years, they have carved out a significant market share, and hence if you want an ultrasonic humidifier from a top brand, their model V4600 will be a good pick.

Because the brand always aims to make it easy to breathe regardless of the weather and your health, this machine will accommodate two of their menthol VapoPads to help with congestion.

The unit has a wide enough tank opening to ensure refilling and cleaning are a breeze. And you can easily adjust the mist output for a more customized experience. Also, this humidifier will shut down automatically when the water level drops to the minimum point.

When you compare this humidifier to other ultrasonic models, it seems relatively louder. However, the sound it makes is still within acceptable levels and should not disturb you when sleeping.

Pros:

  • Reliable product from a leading brand
  • Accommodates two VapoPads
  • Easy refilling and cleaning
  • Customizable mist output
  • Shuts off when the water level is at minimum

  • Power: 100-240V, 50/60Hz
  • Coverage Area: 250 sq. ft.
  • Tank Capacity: 0.4 gallons
  • Runtime: 25 hours

The cool mist technology used on this humidifier not only makes it easy to breathe but will also be very useful at keeping your skin hydrated and ensuring you get a more restful sleep.

This machine has sleep-friendly features to ensure that you sleep even better. They include quite beeps when you turn it on and off. And the power light will always turn off after 10 seconds to ensure it does not distract you.

The 360-degree mist nozzle allows you to adjust the mist direction, and you also get high and low-speed settings to make this a highly customizable unit. With the one-touch button, control is simple, while the automatic shut off helps prevent accidents.

Although the 0.4-gallon tank is relatively smaller, this humidifier still provides up to 25 hours of runtime, and hence minimizing the refill frequency.

Pros:

  • Cool mist technology allows you to breath easily
  • Simple one-button operation
  • Easily adjustable mist direction

  • Coverage Area: 250 sq. ft.
  • Tank Capacity: 0.4 gallon
  • Runtime: 16 hours

Pure Enrichment PEHUMIDIF measures 8 by 6 by 9 inches, which makes it one of the most compact units on our ultrasonic humidifier reviews. The compact size makes it easy to carry around and also ensures it will take up less space in the room.

Besides the smaller size, this is also an efficient humidifier with 360-degree mist nozzle to ensure the mist will come out in all directions.

With the soothing night light, this will be an excellent humidifier for use in the bedroom, and the easy to take apart design will make cleaning and refills a breeze. Because it has an automatic shut off function, you can set and forget it with no worries.

The 16 hours run time is one of the shortest on our list, and the 0.4-gallon tank is also one of the smallest. But the good news is that both are still good enough to ensure the machine can run at least all night long.

Pros:

  • More compact and portable
  • Diffuses the mist in all directions
  • Includes a soothing night light
  • Shuts down automatically when the tank is empty

Pros:

  • Large water tank capacity
  • Long runtime
  • Customizable mist output

Controlling the mist output is precise and straightforward as this unit will include dual independent mist control nozzles. Because the tank has an extra-large opening, cleaning up this humidifier will be a breeze.

How to Buy the Best Ultrasonic Humidifier

How to Buy the Best Ultrasonic Humidifier

Photo: Miro

1. Power

Your ultrasonic humidifier needs to be powerful enough to ensure it can humidify your home or room adequately. An underpowered model will not only be inefficient but will also consume more energy without doing any significant humidification.

When looking at the power rating, you will also need to consider your current setup and choose a machine that can work with it. You do not want to have to spend more money working on your electrical installation just to be able to use a humidifier.

Most of these units will have a 110-220V, 50/60 Hz rating or something close to this, which should be good enough for use in any house.

2. Coverage Area 

Besides being powerful enough, the best ultrasonic humidifier also needs to have a wide enough coverage to ensure your room will be humidified adequately.

The good news is that these machines will come in different models with varying coverage areas from 100 square feet to over 1,000 square feet.

If you want something for use in a small to medium room size, coverage of 250 square feet like you get with the Pure Enrichment PEHUMIDIF should be enough. But, for medium to large rooms, the 700 square feet coverage you get with the Air Innovations MH-901DA is perfect.

3. Tank Capacity

The tank capacity determines both the continuous runtime that the machine can deliver and also the amount of moisture it can put out into your air.

Models with larger tank capacity like the 1.6-gallon tank on the Air Innovations MH-901DA will provide longer run times as this particular unit will run for up to 100 hours on a single refill.

While still on the tank, you should also make sure that besides a more substantial capacity, the tank also has a wide opening for easy refilling and cleaning.

4. Build Quality

Overall build quality determines the durability of the humidifier and is hence also a crucial factor to take into account when shopping.

Although there are a few that will have a stainless steel housing, most have plastic ones. For the plastic units, it is essential to make sure that it is heavy-gauge enough for maximum durability and is BPA-free to make it safe.

Also, check the quality of other things like the control knobs, lid and other components of the humidifier and make sure they are durable enough.

5. Noise Level

One of the most significant advantages of the ultrasonic humidifiers is that they run more quietly when compared to other types.

However, the level of noise still varies from one model to the other. Hence, it will be vital to consider the specific noise rating of the machine when shopping.

If you intend to use the device in your bedroom, you need something with a sleep mode or low setting with a noise rating of under 30 dBA. For other spaces in the house, a noise rating of under 60 dBA will be preferable.

6. Maintenance

Cleaning and maintenance are an essential part of owning a humidifier. With that in mind, any model that you choose should make things easy for you.

Those that will include an easy-to-remove water tank, have an easy to wipe clean surface and come with detailed maintenance instruction will be the best buy for you.

Conclusion 

The whisper-quiet and filter-free design of the ultrasonic humidifiers will make them some of the most convenient types out there. And if you are on the market for the best ultrasonic humidifier, you can be sure there is something for you on our list.

But, to make your choice even more straightforward, the Levoit LV600HH is our best overall as it not only covers more space but also provides both warm and cool mist.

However, if you prefer to use less money on your ultrasonic humidifier purchase, the more affordable Crane EE-5301W is what we recommend.
