Xiaomi Mijia Smart Air Purifier Max – High CADR HEPA Air Cleaner for Large Rooms

1.6 minutes to purify a 10m² room is the figure Xiaomi publishes for the Xiaomi Mijia Smart Air Purifier Max, based on a measured particle CADR of 1,006.5m³/h. CADR is the volume of clean air the unit delivers per hour, and it is not the same thing as airflow: airflow is what passes through the machine, while CADR accounts for how much of that air the filters actually clean, so CADR is always the lower of the two.

Xiaomi Mijia Smart Air Purifier Max: The CADR Figure

CADR is the number that decides whether a purifier can keep up with a room, and it is worth separating from the litres-per-minute figures that usually sit beside it.

Xiaomi publishes a measured particle CADR of 1,006.5m³/h and a measured formaldehyde CADR of 240.5m³/h, which together give a recommended coverage area of 63 to 108m². Xiaomi also quotes 15,000 litres of clean air output per minute. That is the same clean-air measurement expressed per minute rather than a raw airflow rating, and Xiaomi publishes no separate airflow figure for this model.

99.9% Virus Removal in One Hour

Xiaomi states that the two internal UVC lamps deactivate 99.9% of H1N1 influenza virus within one hour. That is a laboratory figure taken in a sealed chamber, so at home the result depends on the size of the room and whether the doors stay shut.

Xiaomi Mijia Smart Air Purifier Max: The 19.1dB Sleep Mode

Noise drops to just 19.1dB(A) in sleep mode, quiet enough for undisturbed overnight use, while formaldehyde real-time tracking continuously monitors air quality rather than relying on a periodic manual check.

Xiaomi Mijia Smart Air Purifier Max: Who It Suits

It also suits households specifically concerned about airborne illness during flu season, given the independently verified virus removal figures.

This suits large open-plan living rooms and spaces where a smaller purifier would need to run constantly at maximum power just to keep pace. For a compact bedroom, the smaller Smart Air Purifier Elite in the range would be more appropriately sized and quieter for the space.

Xiaomi Mijia Smart Air Purifier Max: The Tabletop Design

A closed top cover doubles as extra tabletop surface, preventing dust build-up on top while adding a practical spot for a lamp, book or remote — a real space-saving detail for a slender, compact body design.

Xiaomi states that the dual UVC lamps deactivate 99.9% of H1N1 influenza virus within an hour, measured in a sealed test chamber rather than a living room.

Is it quiet enough for a bedroom?

Yes, sleep mode drops noise to just 19.1dB(A), quiet for overnight use.

Does it also track formaldehyde levels?

Yes, real-time formaldehyde tracking continuously monitors air quality alongside particle filtration.

Can I use the top as a surface?

Yes, the closed top cover doubles as tabletop space while keeping dust off the internal components.

How often does the filter need replacing?

Xiaomi publishes no filter life figure for this model. The unit and the app signal when replacement is due, and how soon that comes depends on running hours and how dirty the air is.
