Following up its first purifier that tackles potentially harmful formaldehyde, the Purifier Hot+Cool Formaldehyde, Dyson has launched a new version that both purifies and humidifies. The Dyson Purifier Humidify+Cool Formaldehyde brings together Dyson’s latest formaldehyde sensing and destruction capabilities with hygienic UV-C humidification technology.
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, says Dyson.
“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,” says Alex Knox, Vice President of Environmental Care at Dyson. ” 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.”
The solid-state sensor was specifically engineered to detect the potentially harmful pollutant formaldehyde. It works alongside Dyson’s 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, says Dyson. 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.
Both the Dyson Purifier Humidify+Cool and the Dyson Purifier Humidify+Cool Formaldehyde now also feature full machine HEPA filtration. The fully sealed HEPA 13 standard filtration ensures that no air bypasses the filter but also blocks any potential leak points through which dirty air might enter the airflow.
As well as humidifying with purified air, the Dyson Purifier Humidify+Cool and Dyson Purifier Humidify+Cool Formaldehyde use UV-C technology to inhibit bacteria growth, destroying 99.9% of bacteria in the water. Dyson engineers developed a highly reflective PTFE tube through which UV-C light is reflected down its length, ensuring that bacteria are exposed to the UV-C rays multiple times rather than just once, to ensure their destruction. These machines hygienically humidify with treated water vapour, rather than droplets. Both provide up to 36 hours of hygienic humidification and a five-litre water tank gives continuous humidification without regular refilling.
For simple and hassle-free maintenance, Dyson has engineered a deep clean cycle that thoroughly cleans all parts exposed to water, notifying the user when cleaning is required and directing them through the process.
Dyson Air Multiplier Technology projects a stream of hygienically humidified and purified air to every corner of the room. Full-room purification is tested with Dyson’s POLAR methodology, which uses nine sensors and no added ceiling fan in an 81m3 test chamber to replicate a real living room, instead of in small lab tests used in some industry standards.
Auto mode enables the machine to intelligently react to changing air quality and humidity levels, and the machine can be remotely controlled by the Dyson Link App or activated by voice control.
