Xiaomi has announced a new version of its successful Mi Air Purifier. The Xiaomi Mi Air Purifier 2S can be said to be an upgrade of the Mi Air Purifier 2 which was released last year. The new version isn’t superior to the Mi Air Purifier Pro also released last year, but it adds some of the features of the Pro version.
The new Mi AIr Purifier 2S continues with the design language of its predecessors and even features an OLED display just like the Mi Air Purifier Pro. The device’s OLED accurately shows atmospheric particulate matter (PM) that have a diameter of less than 2.5 micrometres, which is about 3% the diameter of a human hair (PM2.5 concentration) as well as temperature and humidity. It also comes with a WIFi connection and the work patterns so that you’ll be abreast with changes in the air quality. It has a laser sensor which assists in the accurate detection of particles as small as 0.3μm in size.
In addition, the Xiaomi AIr Purifier 2S comes with a built-in light sensor that can automatically sense the ambient light changes in order to automatically adjust the screen brightness accordingly. This ensures the light doesn’t stay too bright at night so as not to disturb your sleep. Further, you get a device with a Clean Air Delivery Rate (CADR) value of 310m³ / h and can cover a room the size of between 21-32 square metres. This is quite lower than that of the second-gen Mi Purifier 2 and Mi Purifier Pro. For clarity, the Purifier 2 has a CADR of 406m3/h and can cover a working area of 48 square metres while the Pro version has a 500m3/h CADR and is also capable of covering an indoor area of 60 square meters. 
The Air Purifier 2S also features a more refined three-layer filter that can pick up particles like allergens, animal fur, formaldehyde, dust, pollen and cigarette smoke from the air. The new product also added RFID smart filter identification, simplifying the cumbersome routine reset operation.
