The Xiaomi Smart Air Purifier 4 is a powerful and intelligent air purification solution designed to improve indoor air quality with cutting-edge filtration and smart features. Ideal for homes, offices, and bedrooms, it features a high-efficiency 3-in-1 filtration system that removes 99.97% of particles as small as 0.3 microns—including dust, pollen, pet dander, smoke, and even harmful gases.
This purifier covers rooms up to 48m² and delivers a CADR (Clean Air Delivery Rate) of up to 400m³/h. The built-in PM2.5 sensor continuously monitors air quality and automatically adjusts the purification level based on real-time conditions.
Thanks to Wi-Fi connectivity, the Xiaomi Smart Air Purifier 4 can be controlled via the Mi Home App, allowing you to check air quality, set timers, and adjust fan speeds from your phone. It also supports Google Assistant and Alexa for voice control.
Designed for modern spaces, it features a minimalist body, ultra-quiet operation as low as 32.1 dB(A), and a quick-access filter compartment for easy maintenance.
