Dyson introduced the Purifier Humidify+Cool and the Purifier Humidify+Cool Formaldehyde. The Formaldehyde model combines Dyson’s latest solid-state formaldehyde sensor and full-machine H13 HEPA filtration with hygienic humidification capabilities. Both models automatically purify, precisely sensing and capturing pollutants, while using UV-C technology to remove 99.9% of bacteria in water. “The off-gassing tendency of formaldehyde means that it can build up within the home and go undetected for years, while humidifiers without sufficient water treatment can project polluted water droplets into the air – Alex Knox, Vice President of Environmental Care, says -. Dyson has engineered a machine that tackles both of these problems, providing precise sensing and continuous destruction of formaldehyde, whilst hygienically humidifying for cleaner air”. In an evolution of Dyson’s existing sensing capabilities, the new Dyson Purifier Humidify+Cool Formaldehyde now features a solid-state sensor, specifically engineered to detect the potentially harmful pollutant formaldehyde. “While some other gel-based formaldehyde sensors can deteriorate overtime and are easily confused with other VOC (volatile organic compound) pollution – the company explains -, Dyson’s solid-state formaldehyde sensor works alongside Dyson’s unique algorithm to precisely monitor formaldehyde levels – intelligently ignoring other gases which are detected by a dedicated VOC sensor. Sources of formaldehyde inside the home include pressed wood products, cleaning agents, carpets and do-it-yourself products such as paint, wallpapers and varnishes. Being 500 times smaller than particles the size of 0.1 microns, formaldehyde is particularly difficult to capture. When left undetected, it can lead to prolonged exposure due to continuous release of airborne chemicals, known as off-gassing. This can be exacerbated by modern, well-sealed homes as pollutants become trapped inside and are unable to escape. Dyson’s Selective Catalytic Oxidization (SCO) filter continuously destroys formaldehyde at a molecular level”.
