Dyson Pure Hot + Cool Advanced Technology

To simultaneously purify and heat a whole room properly, the Dyson Pure Hot+Coolâ„¢ purifying heater + fan goes beyond standard tests by automatically sensing pollution, capturing ultrafine pollutants, and projecting purified and heated air using Air Multiplierâ„¢ technology. It is the only purifying heater designed and tested to do this.
With three intelligent sensors, the Dyson purifying heater + fan automatically detects airborne particles and gases and then reports them in real time. 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.
