The Dyson Pure Cool Tower is the 2.0 version of its predecessor (the Dyson Pure Cool Link). With 3 integrated sensors, the temperature, air quality, humidity, PM2.5, PM10, and gas are measured 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 out of 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 are blown into the space every second. Besides that, the air spreader can swivel up to 350 degrees. This means the purifier won't miss anything. You can control the air purifier with the included remote and set it up according to your own preferences.
