Best small cool-mist humidifiers for dorm rooms under $60

Top pick: Honeywell Small Compact Ultrasonic Mini Cool Mist. It's the one I'd put on a dorm desk: genuinely small, ultrasonic and quiet, a half-gallon tank that runs up to 24 hours, and it's sold at several stores, so replacing it later is easy.

Who the others suit:

• Pure Enrichment MistAire Studio — the simplest no-fuss choice if you want a well-known brand and a small footprint.
• Levoit NeoClassic Mini — best if you want a bit more coverage and auto shutoff; it's the most capable of the small ones here.
• Lasko Ultrasonic Personal — tiny and cheap, fine for a nightstand but a very small tank.
• Classic 100 / 3-in-1 models — bigger tanks and more coverage, but they take up more shelf space.

Skip the USB mini bottles and diffuser combos: tiny tanks, and some don't state cool mist at all. Whatever you pick, rinse the tank every couple of days — dorm water leaves film fast.
