The Verdict.

9.4/ 10

Gavler Meta-Score

The default large-room humidifier. Highest published output and real warm + cool. Distilled water and a wash schedule are the price of that mist — skip it if you will not clean an ultrasonic.

Warm + Cool, ~550 mL/h Peak

Hybrid ultrasonic. Warm is the gallons-per-day lever (~280 W). Cool is the quiet overnight at ~26 W. The app does not add moisture.

6 L / 753 sq ft Claim

1.58 gal top-fill, up to 50 hours on low. Large-room tank class — the same volume as the Classic 300S, with a heater.

Ultrasonic Mold / Dust Honesty

Tap water = white dust. A skipped wash = biofilm in the mist. Distilled water and a dry base are the operating cost.
