The Dyson Pure Hot + Cool is the only purifying heater + fan to clean a whole room properly. To simultaneously purify and heat a whole room properly, the Dyson Pure Hot+CoolTM purifying heater + fan goes beyond standard tests by automatically sensing pollution, capturing ultrafine pollutants, and projecting purified and heater air using Air MultiplierTM technology. It is the only purifying heater + fan designed and tested to do this.
