The DREO is the value smart humidifier here, and the listing packs in the connected features: a 4 litre top-fill tank with Wi-Fi, app and voice control through Alexa and Google Assistant, a timer, digital display, humidistat, aroma diffuser and auto shut-off, quoted at a 32 hour runtime with 25 watts of draw at 1.42 kilograms.

A humidistat is the feature that separates a smart humidifier from a manual one, because it lets the machine hold a target humidity rather than running until you switch it off. One listing oddity worth flagging: the voltage field says 120 volts, a US figure, alongside a UK product page. At the time of collection it carried 11,342 ratings at 4.4 stars. Everything here comes from the Amazon listing rather than our own testing.
