Our take on the Smart Humidifier 612S 5L

The Dreo Smart Humidifier 612S is a 5-liter ultrasonic humidifier for bedrooms, living rooms, offices and nurseries. It runs on ultrasonic technology that Dreo bills as whisper-quiet, and a control knob lets you dial mist output from a gentle level to a heavier one. The 5 L tank is removable for cleaning, which puts it in line with other large-tank ultrasonic models; the trade-off is that it is a knob-controlled unit rather than one with app or smart-home control. It suits anyone who wants long runtime and simple operation over connected features.

Questions and answers

Is the 612S the same as the HM512S?
Yes. Dreo states the specifications are identical to the HM512S; only the exterior packaging differs, since the 612S is sold through offline channels.
Does it have app or smart-home control?
No. Mist output is set with a manual control knob. The Smart name does not bring Wi-Fi, an app or voice control.
How long does the 5 L tank last?
Runtime depends on the mist setting. A 5 L tank is large for a room humidifier, so expect multiple nights between refills at low output and much shorter runs at high output.
Is it quiet enough for a nursery?
Dreo describes the ultrasonic operation as whisper-quiet and names nurseries as a use case. Ultrasonic units generally produce little noise beyond a faint water sound.
Will it leave white dust on furniture?
Ultrasonic humidifiers can leave white mineral dust when filled with hard tap water. Using distilled or filtered water reduces it.
How do I clean it?
The water tank is removable and the construction is simple, so the tank and base can be rinsed and wiped regularly to keep the unit hygienic.
Where is the Smart Humidifier 612S 5L cheapest?
At DREO, for $74.99, as of our latest check.
