The Xiaomi Smart Air Purifier 4 is designed to keep your indoor air clean and healthy with impressive efficiency. Its Particle CADR of up to 400m³/h can purify a 20m² room in approximately 10 minutes, thanks to its 360° all-round air intake. Equipped with a three-in-one filtration system, it eliminates 99.97% of particles as small as 0.3µm, including dust, pollen, smoke, and pet dander, making it ideal for allergy and rhinitis sufferers. High-quality activated carbon removes odors and harmful gases such as VOCs, while negative air ionization keeps your home feeling fresh.
This purifier is built for convenience and long-term use. The high-efficiency filter lasts 6–12 months, minimizing replacements. With Auto Mode, laser sensors detect air quality changes and adjust purification speed automatically. The Mi Home/Xiaomi Home app allows remote smart control, and voice commands provide hands-free operation. Real-time PM2.5 levels are displayed on the OLED screen, while Night Mode ensures quiet operation at just 32.1 dB(A). Cleaning is simple, with easily removable grilles and ducts, preventing secondary pollution.
