Xiaomi has released more details about the Mijia Smart Air Purifier with Humidification Pro

The device functions as a dual-purpose appliance that purifies and humidifies indoor air at the same time, a combination that sets it apart from most standalone purifiers, which handle filtration alone.

Active humidification typically matters most during the winter heating season, when indoor air dries out, though air conditioning can produce a similar effect in summer that leaves the added moisture control useful year-round.

Xiaomi rates the unit’s particulate clean air delivery rate at up to 422 cubic metres an hour, a specification that determines how quickly the purifier can process the full volume of air in a mid-sized room.

According to Xiaomi’s official specifications, the purifier removes 99.99% of fine particulate matter, including PM1, PM2.5 and PM10, within one hour, alongside various airborne pathogens and allergens that commonly enter homes on clothing, skin and hair, a detail that makes the feature particularly relevant for allergy sufferers even when windows stay shut.

Beyond filtration performance, the unit’s physical footprint also affects where it fits in a home. The purifier measures 320 by 320 by 810 millimetres and includes an ultra-quiet sleep mode rated at just 14.6 decibels, a level quiet enough to run overnight without disrupting sleep in most bedrooms.

That humidification system also addresses a common hygiene concern, since standing water in a tank can breed bacteria or release microbes into the air, and Xiaomi tackles this by integrating UV sterilization, a feature not always found on humidifying purifiers sold at a similar price.

This combined approach to purification and humidification also reflects a broader shift in the smart home category, where manufacturers increasingly fold several single-purpose appliances into one connected device rather than selling separate units for each function.

Beyond its feature set, Xiaomi has not yet confirmed release dates or regional availability, though it offered the unit during an initial crowdfunding campaign in China at around 255 US dollars, with retail pricing in Europe or North America likely to land higher than a direct currency conversion would suggest.

The global listing suggests Xiaomi is preparing a wider rollout beyond its home market, and the company is expected to confirm pricing alongside specific launch markets as that expansion takes shape in the coming months.
