Introducing Xiaomi Smart Air Purifier 4 series
2The Xiaomi Smart Air Purifier 4 series promises a healthier, cleaner, and reduced-allergen indoor air environment with different options for its users. The 4 Pro has a 3-in-1 filtration system that combines electrostatic charge and mechanical technologies to trap up to 99.97% of air pollutants as small as 0.3 microns.
It also integrates both PM2.5 and PM10 sensors to detect inhalable particles of different sizes. An ionizer has been added to help capture floating pollutants. In addition, the 4 Pro can filter the air of a 40m2 living room entirely every 15 minutes.
Users also get an OLED touch display to view AQI, temperature, and humidity statistics at a glance as well as adjust settings in a few taps. The Air Purifiers can be controlled via the Xiaomi Home App and supports Google Assistant and Amazon Alexa.
