The Levoit LV600HH is a high-end ultrasonic humidifier with a strong initial effectiveness that drops over time. This unit is programmable for humidity level, run timer, and auto-shutoff with a digital user interface that is fairly intuitive. The Levoit has a tank with a large opening and stands on its own to fill. This unit has several parts and pieces with lots of nooks and crannies where mold and bacteria can hide. It comes with a small brush to help you with cleaning, but you'll need a bottle brush and disinfectant as well. While this humidifier works well enough and we like the programmability, it creates more noise than much of the competition and it sports one of the highest prices making it a poor choice for most families.

Our Analysis and Test Results
Levoit lacks a company "about us" web page on their site, so it is difficult to see who they are or determine their background. The website boasts health and wellness with products ranging from humidifiers and air purifiers to salt lamps and yoga essentials. They are in California, and they actively encourage becoming part of their online "community."
Ease of Cleaning
The Levoit is easy to clean thanks to a large opening you can fit your hand inside, and a small brush for reaching those nooks and crannies where bacteria and mold can hide.
This humidifier has more parts than most of the competition with lots of items you need to remove for cleaning and more things you could forget to clean. It needs to be regularly disinfected and descaled if minerals build up on interior surfaces. Some places in the base are small and hard to clean (above left), but the mist tube is not part of the tank and is removable from the bottom for easy cleaning. You'll need a bottle brush to clean the tube making your cleaning toolkit for this unit one of the largest in the group. Don't forget the diffuser pad area (above right) also needs to be cleaned if you choose to use it.
This unit is not as effective as much of the ultrasonic competition. The Levoit is relatively strong in the beginning creating more humidity at the start than some of the other options. However, as time went on, it wasn't able to keep up, and after an hour, it had the 4th lowest amount of humidity in the air out of the ultrasonic products we tested.
The Levoit is on the louder side when compared to the competition, but it is still relatively reasonable. It registers 44 decibels with several other ultrasonic options coming in with sound below 40. The loudest ultrasonic product is 47 decibels, with the evaporative option rating over 60 decibels.
Ease of Use
This humidifier has several features to customize your experience. While the user interface is digital and not as straightforward as a single dial adjustment, it does mean you have more control over your environment, and you don't need to tend to the machine as much as you would a dial product. The Levoit has an auto-shutoff, a humidistat to program humidity levels, and warm or cool mist options. It also comes with a remote for easy adjustments from the doorway, so you don't need to enter the nursery to make changes.
The tank on the Levoit is easy to fill with a large opening and the ability to stand on its own in the sink. It doesn't have a functional carry handle, but not many do.
