The most hygienic pick, with a dishwasher-safe tank, a UV-treated pump and auto-dry. But the tank is under a gallon, it's louder than an ultrasonic, there's no visible mist to reassure you, and a roughly $30 filter is due about every six months.
Top complaints
- Small tank
Wirecutter says the 0.9-gallon tank falls just below its 1-gallon guideline, so larger rooms or very dry climates will mean more refilling.
Source: Wirecutter - Filter cost
The Spruce says the wick filter costs about $30 every six months or so, and Wirecutter says it is designed for a roughly six-month replacement cadence.
Source: The Spruce, Wirecutter - Louder than ultrasonic, and no visible mist
Wirecutter notes its fan makes it louder than an ultrasonic model, though still well below conversation level. The Spruce reports that testers of evaporative models, including this one, wished they could see mist to know it was working.

What owners love
- Most sanitary design Wirecutter tested
It has a dishwasher-safe tank, a UV light in the water pump, and an auto-dry mode that dries the wick after use. Wirecutter says the room never felt musty, even at about 75% humidity.
Source: Wirecutter - Easiest to fill
The Spruce says it is the only pick you can fill by pouring water into the top without removing a lid.
Source: The Spruce - Good app, 3-year warranty, efficient motor
Wirecutter praises a clean, non-pushy app, an energy-efficient DC motor, and a three-year warranty with registration.
