Xiaomi's new 2-in-1 air purifier and humidifier looks impressive on paper — but good luck buying one

Xiaomi has opened crowdfunding for the Mijia Purifier Humidifier 3 Pro, a combined air purifier and humidifier that starts at 1,699 yuan (around $250 / £200) on the Xiaomi Youpin platform. The spec sheet is genuinely strong for the price — but as of now, there's no confirmed path to buying one in the US or UK.

The specs

The headline number is a humidification rate of 2,000 mL per hour, which is five to seven times higher than most compact home humidifiers. That output is designed to handle large living rooms or open-plan spaces where smaller units struggle to make a dent.

On the purification side, the device posts a CADR (clean air delivery rate) of 422 m³/h for airborne particles and 247 m³/h for formaldehyde — numbers that put it alongside dedicated air purifiers rather than afterthought combo units. It ships with an 8-liter water tank that supports around 16 hours of continuous use at full load.

Xiaomi also built in a one-way water circulation system to prevent stagnant water from re-entering the main tank — a detail that matters for keeping bacterial growth in check. The tank fills from the top without stopping the unit, or you can remove it entirely to fill at a tap.

The smart home angle

The top panel carries a dome-shaped LCD showing live humidity, temperature, and air quality status. It connects to the Mijia app for scheduling and historical data, and supports Xiao AI voice commands. In sleep mode, noise drops to 28.1 dB(A) — quiet enough for a bedroom. Built-in wheels make it easy to move between rooms despite its size.

The catch

Notebookcheck notes there is "no indication" of a global launch. US and UK retailers currently stock only older, entry-level Xiaomi humidifiers — think 350 mL/h models at £40–60 — and no purifier-combo equivalent appears anywhere on Amazon.co.uk, Amazon.com, or major US retailers. The US mid-range ($150–300) is already well-served by Levoit, Dyson, and Honeywell combo units that carry proper warranties and domestic customer support.

Grey-market routes via AliExpress or eBay exist, but import duties and the absence of any warranty coverage are real friction points. The crowdfunding price closes out after July 22, 2026, with retail expected to rise to roughly 2,799 yuan (around $390) afterward.

If Xiaomi does push a global version, it would land in a competitive market at a competitive price. Right now, it's one to watch — not one to order.
