Product story
Engineered for open-plan living-dining rooms, large master suites, clinics, and offices, the Xiaomi Smart Air Purifier 4 Pro (model AC-M15-SC) delivers up to 8,330 liters of purified air per minute with a high Particle CADR of 500m³/h and a Formaldehyde CADR of 185m³/h. Drawing air through 360-degree full-body lower intake grilles, it purifies a 40m² living room in approximately 15 minutes and provides an effective room coverage area of 35–60m².
Unlike standard purifiers that only track fine PM2.5 particles, the Smart Air Purifier 4 Pro incorporates a dual-effect PM2.5/PM10 laser sensor that simultaneously monitors coarse inhalable particles (2.5–10μm such as seasonal pollen, construction dust, ash, and pet dander) and fine respirable particles (≤2.5μm such as traffic smog and cooking smoke), displaying both live metrics alongside indoor temperature, relative humidity, and a color-coded air-quality light strip on its circular front OLED touch screen. Its expanded 3-in-1 cylindrical filter combines 24,000cm² of High Efficiency filter media (capturing 99.97% of 0.3μm particles) with 650,000mg of high-quality activated carbon for household VOC and odor adsorption, lasting 6 to 12 months and featuring an integrated RFID chip that automatically identifies new filters. A built-in negative air ionizer releases negative ions to keep indoor air fresh.
In Night Mode, acoustic output drops to a quiet 33.7dB(A) with OLED screen lights switched off for undisturbed sleep, and the brushless 50W rated motor consumes as little as 0.8kWh across 24 hours of normal operation. The top outlet grille unscrews easily so you can wipe down the internal fan blades and air ducts, while the Mi Home / Xiaomi Home app provides remote scheduling, stepless fan speed control, and Google Assistant or Amazon Alexa voice integration.

Helpful answers
Product-specific answers maintained with the catalog information.
The 4 Pro increases Particle CADR from 400m³/h to 500m³/h (expanding coverage from 28–48m² to 35–60m²), upgrades to a dual-effect PM2.5/PM10 laser sensor for coarse pollen/dander detection, and uses a larger filter with 24,000cm² media and 650,000mg activated carbon.
No. Because the 4 Pro has a larger 275 x 275 x 680 mm housing, it uses the dedicated Xiaomi Smart Air Purifier 4 Pro Filter with built-in RFID recognition.
Yes. Switching to Night Mode or adjusting brightness in the Xiaomi Home app turns off the OLED glare while running the fan at 33.7dB(A).
