Good for humidifying a mid-size room for a full day on its lowest setting, this cool mist evaporative humidifier can be operated on one of three speed settings, varying the moisture output along with the sound level. Compared to similar units, it's pretty quiet. With its large tank handle, we found it easy to transport, and the large opening means refills and cleaning are not cumbersome. The filter is easily accessible for cleaning and replacing as needed.
With its compact design and shockingly quiet operation, you might forget you are using a humidifier. That is why the auto shut-off feature comes in handy when the water level is low or the tank is misaligned in case you actually do forget. The one-button operation makes this humidifier very intuitive to use and the button back light makes it easy to see in the dark in case you need to turn on the built-in night light or adjust the mist setting. While it may not be the easiest to clean because of a medium sized tank opening, this humidifier comes with a cleaning brush to help make maintenance a little less arduous.
This 2-in-1 device not only moistens the air with a cool, gentile mist, but it also operates as an essential oil diffuser to disperse sweet scents and good vibes. Use it with water alone, or add a couple drops of your favorite fragrance to enhance the air with soothing aromatherapy. Plus, more than 32,000 (!!!) Amazon reviewers have given it a seal of approval for its multiple misting modes, beaming nightlight, and auto shut-off capabilities.
The larger 1.5 gallon tank on the Levoit means you can service a larger space (up to 750 square feet) or that it won’t have to be refilled quite as often (up to 36 hours on the low setting!). It operates with both ultrasonic warm and cool mist so you can get the benefits of both. The handy humidity readout means you can easily know the status of the room without an additional meter. You can operate it with the panel's touch controls or the remote, adding a layer of convenience most lack. Even better, it has an automatic mode to choose the mist level without your interference.
Not only does this humidifier come with both warm AND cool mist, but it has a 5L tank and two nozzles that rotate 360* to allow for total room coverage. A built-in humidity sensor means you can choose your desired level and the machine stops once that level is reached. Bonus: remote control and easy-to-clean reservoir.
