Captures dust, allergens and bacteria. Even destroys formaldehyde. Hygienically humidifies by removing 99.9% of bacteria in the water. Only Dyson’s latest purifiers are fully sealed to HEPA H13 Purifies by removing 99.95% of ultrafine particles Hassle-free Deep clean cycle Improve the air quality inside your home Pollution isn't just a problem outside. In fact, the average home can be up to five times more polluted than the air outside8. Fortunately, there is a solution to both – all year round. Why humidification matters This machine has in-built intelligence that can help with dry air by adding moisture automatically. This optimises humidity levels in the air by projecting an invisible stream of evaporated water – with no mist. And purification too Many household items release pollutants like pollen, dust, pet allergens, odours, and smoke. Dyson purifiers sense and capture them, in advanced HEPA and carbon filters. Dyson purifier humidifiers are tested beyond the industry standard Dyson test their purifier humidifiers in a room size of 81m³, with nine sensors that continuously measure air quality. Some other manufacturers use a small 28.5m³ chamber, with only one sensor and a fan to boost circulation. Senses and reports, automatically Three sensors constantly monitor your air. Dyson's unique algorithm diagnoses pollutants at a molecular level – reacting to purify and humidify before displaying live air quality in real-time reports. You can use the MyDysontm app to do this. Captures pollutants with advanced HEPA filtration A carbon filter removes gases such as benzene and HEPA filter captures 99.95% of particles as small as 0.1 microns. Destroys potentially harmful bacteria Dyson Ultraviolet Cleanse technology exposes every drop of water to a powerful λ275nm UV light. This kills 99.9% of bacteria in the water. Cleansed water is then evaporated by the biostatic 3D air mesh, before hygienic, humidified air is projected throughout the room.
