Xiaomi Smart Air Purifier 4: Power and Intelligence for Large Room Air Quality
Maximum Cleaning Power for Big Rooms
The standard Purifier 4 model offers significant coverage and speed:
-
Clean Air Fast: With a Particle CADR of $400 \text{ m}^3/\text{h}$, it pushes out over 6,600 liters of purified air every minute. It can fully clean the air in a large room (up to $48 \text{ m}^2$) in about 10 minutes.
-
Three Layers of Protection: The advanced 3-in-1 filter provides total defense:
-
Stops Big Stuff: The Pre-Filter catches hair and large dust particles.
-
Traps Allergens: The High-Efficiency Filter traps $99.97\%$ of tiny particles ($0.3 \mu m$), including pollen, pet dander, and other irritants, making it a must-have for allergy sufferers.
-
Eats Odors: The Activated Carbon layer absorbs and eliminates common household smells like cooking smoke, pet odors, and chemical fumes.
-
Smart Monitoring You Can See
The Purifier 4 makes managing your air quality simple and intuitive:
-
Clear Touch Screen: The smart OLED touch screen gives you clear, live information on air quality ($\text{PM2.5}$ levels), temperature, and humidity. Adjust settings with a quick touch.
-
Feel the Freshness: The built-in Negative Ion Generator releases fresh ions into the air, similar to what you feel near a waterfall, helping eliminate stale air and improving your overall well-being.
-
Control with Your Voice: Easily connect to the Mi Home App for remote scheduling and filter alerts. You can also control it hands-free using Google Assistant and Amazon Alexa.
Designed for Comfort
-
Quiet Sleep Mode: Running as low as $32.1 \text{ dB}(\text{A})$ in Night Mode, it’s quieter than a whisper. The screen light turns off, ensuring your sleep is completely undisturbed while you breathe clean air.
-
Easy to Clean: The filter lasts 6–12 months, and the top grille easily unscrews, letting you quickly wipe down the fan blades to keep everything fresh.
Choose the Xiaomi Smart Air Purifier 4 for powerful, smart cleaning that keeps your entire living space fresh and healthy.
