Pure cool air purifier and tower fan

The first Dyson personal purifier fan. Purified air to cool you, with our latest air projection technology.

Summary. An air purifier will not keep a room cold, and unless it is operated at a high fan speed, it will not provide the amount of airflow required to provide even a cooling effect from air circulation. For true cooling, an air conditioner or fan should be considered.

The Dyson Pure Cool™ purifying tower fan senses harmful pollutants and gases, before capturing those as small as 0.1 microns ¹ in its glass HEPA filter. It then projects purified air around the whole room using Air Multiplier™ technology, while diagnosing and reporting its findings in real time.

Dyson fans and purifiers have no energy-hungry cooling elements like air conditioning units, they aren't designed to lower the room temperature. Our products cool you, not the room. They work by circulating the ambient air in the room.
