2 in 1: Air purifier and fan. Purifies and cools the entire air and continuously decomposes formaldehyde. Detects pollutants in real time. Automatically detects formaldehyde, particles and gaseous pollutants in the air, analyses them and generates real-time air quality reports. Captures pollutants thanks to its activated carbon and HEPA H13 filters arranged at 360° in the base of the device. Hermetic filtration includes an activated carbon filter to capture gases and a HEPA-H13 filter made of glass wool that captures 99.95% of microscopic particles as small as 0.1 microns. The catalytic filter absorbs formaldehyde and destroys it. It is not necessary to replace the filter. Thanks to the Air Multiplier technology, which generates an even, powerful air flow of 290 litres of air per second, the purified air can be circulated throughout the room. Fully sealed air circulation and filtration system. So that no absorbed pollutants escape. Thanks to the wide distribution of purified air, this appliance provides pleasant refreshment at high temperatures. Thanks to the reduction in vibrations, this model is 20 % quieter than the previous version. Distributed in the air flow behind the appliance. To purify the air without getting cold. With the LCD screen and the Dyson Link app, you can monitor the air quality at any time. Thanks to the adjustable angle of rotation, the purified air is distributed throughout the room.
