How to choose
Read coverage as the maker figure
Coverage tells you the room size the maker rates a humidifier for. In this list the YOKEKON is rated for 800 sq ft, the DREO for 700 sq ft and the Homedics for 400 sq ft. Measure your room first, then match the maker figure to that area. The AIRCARE holds 18.93L and runs up to 55 hours per fill, so weigh tank size and runtime alongside coverage.
Tank size against runtime
Tank size and runtime work together: a larger tank holds more water, and runtime tells you how long one fill lasts. The DREO holds 11L for up to 100 hours, the AIRCARE holds 18.93L for up to 55 hours, the YOKEKON holds 14L for up to 48 hours, and the Homedics holds 3.67L for up to 45 hours. Compare both figures with your refill routine.
Controls, timers and lights
Timers differ: the YOKEKON timer runs 1 to 12 hours and the DREO timer runs 12 hours. Lights differ too: the YOKEKON has an ambient light and a night light, the DREO has RGB lights, and the Homedics has a night-light.
