We design our purifying fans to go beyond test chamber conditions and focus on real home conditions – this is more than just having an efficient filter.¹ Dyson engineers and research concluded that to clean an entire room properly, you need to sense pollution events automatically, capture ultrafine pollutants and project cleaner air around the room using Air Multiplier™ technology. Only the Dyson purifying fan is designed and tested to do all of this.²
Senses pollutants in real time
Automatically detects and reports air quality levels in real time on PM 2.5, PM 10, VOC and NO2.
Captures pollutants with 360° sealed HEPA and activated Carbon filters
The fully-sealed filter system combines an activated Carbon filter to remove gases, and a Glass HEPA filter that captures 99.97% of microscopic allergens and pollutants as small as 0.3 microns.
Projects powerful airflow
Air Multiplier™ technology delivers over 77 gallons per second of smooth, yet powerful airflow – circulating purified air throughout the whole room.²
Automatically senses, captures and projects – then reports to your Dyson Link app.³
