The most complete budget spec sheet we found in any family
Xiaomi appears in one family here: air purifiers.
CADR, published plainly. The Smart Air Purifier 4 Compact states 230 m³/h particulate CADR and 185 m³/h formaldehyde CADR — both real, comparable figures, at roughly a sixth of the price of the premium purifier in this family.
An OLED screen that tracks filter life. Rather than a vague indicator light, the display shows live air-quality readings and a filter countdown, guided by Xiaomi’s own 6–12-month replacement window.
What’s missing. Xiaomi doesn’t publish an exact power-consumption figure or a precise ionizer output for this listing — gaps we mark “Not published” rather than estimate from other models in the range.
230 m³/h CADR · True HEPA · up to 27 m²
A compact HEPA purifier Xiaomi rates at 230 m³/h particulate CADR and 185 m³/h formaldehyde CADR for rooms up to 27 m². An OLED touchscreen shows live air quality, sleep mode is rated at 18.3 dB, and the app tracks a 6-12 month filter life.
Best for: A bedroom or small home office where a compact footprint and a low purchase price matter more than covering a large open-plan room.
