The Xiaomi Smart Air Purifier 4 delivers quick and effective purification, cleaning an average-sized room in just 7 minutes with a CADR of 400 m³/h. Built for Indian homes now facing GRAP Stage 3 air quality concerns, it covers up to 516 sq ft perfect for bedrooms or medium living areas. Its triple-layer filtration system combines a primary filter, True HEPA filter, and activated carbon layer to capture 99.99% of ultra-fine particles (as small as 0.1 µm), removing dust, smoke, pollen, and pet dander effectively. It also releases negative ions to freshen the air and reduce allergens naturally. Smart features include app, remote, and voice control via Alexa or Google Assistant, while its real-time air quality LED display keeps you informed. Despite its performance, it runs quietly and consumes only about 0.8 kWh daily, making it energy-efficient and dependable for everyday use.
