How to choose
Tank size and runtime
Tank size and runtime decide how long you can run before refilling, so compare both together. The raydrop has a 1.7 L tank for 9 hours, the DREO has an 11 L tank for 100 hours, the Frida has a 2.5 L tank for 60 hours on low, and the Boxing has a 3 L tank for 30 hours. The MEGAWISE has a 3.5 L tank. Match the tank and runtime figures with how long you run the humidifier each day.
Coverage and noise
Coverage tells you the room size each maker rates the humidifier for, and noise tells you how loud it runs. The raydrop is rated for up to 220 sq ft by the maker, the DREO for up to 700 sq ft, the Frida for up to 320 sq ft and the Boxing for up to 317 sq ft. For noise, the raydrop runs at 26 dB, the DREO at 21 dB, the MEGAWISE at 24 dB and the Boxing at 20 dB. Match coverage and noise with the room size and the hours you run it.
Shutoff and extras

The raydrop, MEGAWISE, Frida and Boxing have auto shutoff, and the raydrop adds a low-water indicator that turns red, while the Frida adds a low-water indicator. The raydrop and Boxing each come with a cleaning brush.
