Packaging and appearance

The Xiaomi Mi Smart Antibacterial Humidifier features a fairly elegant and minimalistic design. The white cylindrical body is of just the right size, making it easy to place on your bedside table or the floor. A small switch is used to adjust fog settings, and there is a small indicator on top of it to show when the humidifier is running out of water. In addition, it has 7 lighting modes, so you can choose the color to fit the interior.

A convenient design allows you to refill the water tank directly from the top. Regarding power, the humidifier is equipped with a 220V type A power plug: it doesn’t have a built-in battery and must always be plugged in.

In addition to the unit itself, the packaging includes a Chinese manual with no English translation is available, which might make the initial setup confusing. Everything is packed in a plain but sturdy cardboard box, so you might want to wrap it if you plan to give it as a gift.

In the case of the Xiaomi Mi Smart Antibacterial Humidifier, the stress is on the “antibacterial” feature powered by the UV-C Instant Sterilization system. The water tank is equipped with an ultraviolet lamp that can eliminate up to 99% of bacteria in the water. After the sterilization, the water droplets are released as a mist with a 280-300 ml/hour rate of humidification and 3 different power settings, the device can cover an area of 21-30 m³. With a full tank, it can last for up to 12-15 hours, and when the water levels reach the minimum, the indicator turns red and automatically turns off the device.

When you search for the device on AliExpress, you may come across the words “aroma essential oils compatible” in the description – but there is a small issue here. While the humidifier can be used with water-based aroma oils (spoiler alert: not really, but we’ll come back to that), you absolutely cannot add pure essential oils – it will only damage the device. But after studying customer reviews, we have also learned that it is not advisable to use water-based aroma oils as well! You’ll be forced to clean up the device from the oil residue clogged in the mist dispenser, so just stick to pure distilled water.

Moving on to control options, thanks to the 2.4 GHz Wi-Fi network, the device can be integrated with Google/Alexa voice assistants (for the ‘on/off’ commands) or with Xiaomi Mi Home App, which unlocks more remote-control options.

Regarding customer impressions, the humidifier lives up to customers’ expectations: it helps to relieve dryness in small and medium-sized rooms even on low settings.
