The Dyson Pure Cool Link air purifier is connected to the Internet via Wi-Fi. With an intuitive smartphone app, the user can control the current air quality at home in real time and, as required, can also clean the air from anywhere. Through the efficient combination of a HEPA filter and an active carbon filter, the air purifier removes 99.95 per cent of all particles, down to a size of 0.1 microns. It filters pollen, mould spores, and fine dust from the air, but also odours, noxious fumes, allergens and bacteria.
