ROSEKM 2.0L Filterless Cool Mist Humidifier, 24-Hour, Compact

Filterless, so there is nothing to buy again once you own it. For a humidifier you expect to run every night through winter, that removes the running cost entirely.

The footprint is just over five inches square, which is the point: it fits on a nightstand next to a lamp and a phone without crowding them out. Two liters gives twenty-four hours on the lowest of its four mist levels, or ten hours at full output. Noise stays under 26 dB and the indicator light switches itself off after ten seconds so nothing glows at you all night.

A cleaning brush is included, and the manufacturer covers it for five years.
