Pros / This humidifier doubles as a colorful night light and aromatherapy diffuser.

Cons / The tank lasts less than eight hours on full.

 Verdict / This cool mist humidifier is a good option for a small bedroom or office, but it lacks the capacity to humidify larger spaces.

Designed in the shape of a water drop, the Ultrasonic 2.8-Liter Cool Mist Humidifier is an affordable option for people who need more humidity in their air but don't particularly need it to cover a large area. This humidifier design is sold by multiple companies that rebrand the unit with their own logo and resell it. Holding nearly 0.75 gallons of water in its semi-opaque reservoir, this air humidifier can put approximately 1.2 gallons of mist into the air on its lowest speed, and more if you refill it a couple times while running it on high.

This humidifier has a small coverage area compared to other cool mist humidifiers in our review. While most can humidify rooms of 500 or 600 square feet, this one can only provide mist for 160 square feet. It's best used only in small bedrooms or offices.

This humidifier does not have any warming capabilities, so if you use it in a child's bedroom, you don't have to worry about scalding water tipping onto your child if they pull it over. However, the best humidifiers still give you the choice whether to have warm or cool mist, which is a nice option to have for different times of year. A fun feature of this air humidifier is the softly glowing LED that doubles as a pleasant night light at the push of a button, with seven colors to choose from. You can also turn off the light if you want darkness while you sleep.

Like the best humidifiers, this unit has a filter that helps purify the water before the ultrasonic vibrations convert it to mist. This filter makes it possible to use regular tap water with the humidifier without having to purchase distilled water. The nozzle sits on top of the water tank and rotates 360 degrees, allowing you to direct the fine mist where you want it to be.

A simple manual dial on the front controls the amount of steam the humidifier produces. While this unit does not have a digital display, the oversized knob is easy to manipulate until you get the right flow of mist. A unique feature is the small built-in draw that allows you to add essential oils to a sponge for dispersal. Never add the oils directly to the water in the tank, as this may deteriorate the plastic the tank is made of.

There is no manufacturer support beyond the limited one-year warranty against manufacturer defects. If you have questions or problems with this humidifier, you will have to get in contact with your reseller, as Avalon does not have a direct support website.

Summary

The Ultrasonic 2.8-Liter Cool Mist Humidifier is a good choice for small bedrooms or office spaces, and the colorful light and ceramic mineral filter give it great appeal. However, it's not particularly versatile. To humidify a larger area or run the cool mist on full power longer than six hours, you will need a larger and more powerful humidifier.
