The Dyson Purifier Hot+Cool Formaldehyde is an air purifier, fan and fan heater in one and detects and removes pollutants in real time thanks to its activated carbon and HEPA H13 filters, which are arranged at 360° in the base of the appliance. The 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, including formaldehyde. Thanks to Air Multiplier technology, the appliance generates an even, powerful air flow of 290 litres of air per second, allowing the purified air to circulate throughout the room. Fully sealed air circulation and filtration system so that no absorbed pollutants escape. Warm in winter, cool in summer, clean air all year round - thanks to the wide-area air distribution, the entire room is heated evenly. At high temperatures, the powerful flow of purified air provides pleasant refreshment. Real-time information is shown on the LCD display. Thanks to the adjustable rotation angle of up to 350°, the purified air is distributed throughout the room. In night mode, the air is controlled and purified without disturbing your sleep thanks to extremely quiet settings and reduced screen brightness.
