Dyson Pure Hot+Cool White Silver HP04
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
Automatically detects airborne particles and gases, then diagnoses and reports them in real time.
Activated carbon filters remove gases. Sealed HEPA filters capture 99.95% of ultrafine particles such as allergens and pollutants.2
Only Dyson purifying fans and heaters have Air Multiplier™ technology and 350˚ oscillation, to project air around the whole room.1
