How to choose
Match coverage to your room
Compare the coverage figure each maker gives with your room's floor area. The Levoit maker rating is up to 753 sq ft, the Homedics maker rating is up to 506 sq ft and the Crane maker rating is up to 500 sq ft. A rating above your room size leaves headroom for doors and open layouts, while a rating well below it means the unit must run at high output to keep up.
Warm mist, cool mist, and controls
All four picks offer warm and cool mist, so the choice turns on controls. The Levoit and the Crane include a remote. The Levoit and the Homedics include a timer. The Winix and the Homedics use a programmable humidistat that holds a set humidity level. Decide if you want to adjust mist from across the room or set a target level and let the unit hold it.
Tank size and refill rhythm
Tank size sets the refill rhythm. The Homedics and the Winix hold 2 gallons each, the Levoit holds 6 liters and the Crane holds 4.5 liters. Run time per fill runs from 24 hours on the Crane to 120 hours on the Winix, with the Levoit at 50 hours and the Homedics at 90 hours. A larger tank with a longer run time suits rooms where refilling every day would be a chore.
