    Dyson launches its first purifying humidifying fan with fully-sealed HEPA filtration

    The Dyson Purifier Humidify+Cool brings together Dyson’s latest full-machine H13 HEPA filtration with hygienic UV-C humidification technology, responding to today’s climate of heightened pollution and hygiene awareness.

     

    The Dyson Purifier Humidify+Cool efficiently captures H1N1 virus ¹ and 99.95 per cent of particles as small as 0.1 microns such as allergens, bacteria, pollen and mould spores², while using UV-C technology to remove 99.9 per cent of bacteria in water³.

     

“Purifiers that aren’t properly sealed can leak pollutants, while humidifiers without sufficient water treatment can project polluted water droplets into the air. Dyson has engineered a machine that tackles both of these problems, pioneering new full-machine HEPA 13 filtration to ensure no dirty air bypasses the filter, whilst hygienically humidifying for cleaner air.”

- Alex Knox, Vice President of Environmental Care

  • Hygienic humidification & improved filtration

    Building on Dyson’s commitment to hygienic and clean air, the Dyson Purifier Humidify+Cool now also features full machine HEPA filtration. While many purifiers claim HEPA filtration, if they are not adequatly sealed, indoor pollutants can bypass the filter and escape.  In addition, modern air conditioning and central heating can cause indoor air to dry out. Humidifiers are a well-established solution to dry air in the home, but dirty reservoirs and filters in humidifiers can quickly breed bacteria and mould⁴. In some humidifiers, this can then be carried in the water droplets of mist or steam released into the air⁵.

     

    Ever-dissatisfied, Dyson engineers have re-engineered the machine airflow pathways to achieve fully-sealed HEPA 13 standard filtration⁶ – not only ensuring that no air bypasses the filter but blocking any potential leak points through which dirty air might enter the airflow. This means Dyson’s Purifier Humidify+Cool Formaldehyde captures H1N1 virus⁷ and 99.95 per cent of particles as small as 0.1 microns such as allergens, bacteria, pollen and mould spores⁸. Full-machine HEPA is a novel concept and a global standard test method doesn’t yet exist. Dyson have pioneered a filtration efficiency test that looks at filters within the machine and whole machine sealing.

     

    As well as humidifying with purified air, the Dyson Purifier Humidify+Cool Formaldehyde uses UV-C technology and silver strands in the evaporator to inhibit bacteria growth, destroying 99.9 per cent of bacteria in the water⁹. 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. Inside the  evaporator, interwoven silver strands provide biostatic properties to inhibit bacteria growth and the water is evaporated into a stream of purified air, drawn through Dyson’s 360-degree filters. This hygienically humidifies¹⁰ with treated water vapour, rather than droplets. The machine provides up to 36 hours of hygienic humidification and a five-litre water tank gives continuous humidification without regular refilling.

    Deep clean cycle

    Some water types can leave mineral residue such as limescale on the evaporator and conventional humidifiers can be difficult to deconstruct and clean, increasing the chance of inadequate machine care. 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. 

    Air Multiplier Technology – whole-room purification

    Dyson Air Multiplier™ Technology projects a stream of hygienically humidified and purified air to every corner of the room¹¹. 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 App¹² or activated by voice control¹³.
