The Dyson Pure Cool Desk is the 2.0 version of its predecessor (the Dyson Pure Cool Link). Its 3 integrated sensors measure the temperature, air quality, humidity, PM2.5, PM10, and gas indoors. You can read the data off the LED display. The same goes for information regarding the replacement of the filters. The HEPA filter filters up to 99.95% of allergens, dust, and viruses from the air. The active carbon filter filters gases and foul odors out of the air. Thanks to the 'Air Multiplier' technology, 290 liters of clean air gets blown into the space every second. On top of that, the air diffuser can rotate up to 350 degrees. That means the purifier won't miss any corner. You can control the air purifier using the included remote or app (iOS and Android), and set it up according to your own preferences.
