Automatically cleans and heats a whole room properly, capturing 99.95% of harmful pollutants.

To simultaneously purify and heat a whole room properly, the Dyson Pure Hot+Cool™ purifying fan heater goes beyond standard tests by automatically sensing pollution, capturing ultrafine pollutants, and projecting purified and heated air using Air Multiplier™ technology. It is the only purifying heater designed and tested to do this.1
