Our take on the Humsure 4.5L Cool Mist Ultrasonic Humidifier

The Humsure is a 4.5-liter ultrasonic cool-mist humidifier with three mist levels putting out 100 to 260 ml/h, rated to run 17 to 45 hours per fill. It adds a low-water alert, automatic shut-off, seven-color ambient lighting and mechanical buttons with LED indicators. Its 25 dB rating is quiet enough for a bedroom, and the 4.5 L tank is larger than most compact units, so fewer refills. It suits people who want long overnight runtime and simple dial-style controls; it lacks a humidistat, remote or app control that pricier rivals offer.
