The Vicks VEV400 is a cool-misting evaporative humidifier designed for medium-sized spaces, with an advertised coverage of 400 ft2. It features a bottom-filling tank with a usable capacity of 4.8L (1.3 gal), providing a maximum continuous runtime of over 30 hours. Similar to other Vicks humidifiers, such as the Vicks V3900, you can insert a scented pad into the unit to add a menthol-like fragrance to the mist.
This humidifier is suitable for general home use. While its humidification capacity may be limited for very large areas like open-concept living rooms, it performs well in most bedrooms, offices, and smaller dorm rooms. It lacks automatic features, including auto-off and self-adjusting mist functions, but offers a long runtime, allowing you to run it overnight without concerns of it running dry. Cleaning is also straightforward. Pros: Easy to clean. Long runtime. Cons: Capacity is a little limited for very large spaces. No auto-off function.
