See how the Dyson Pure Hot + Cool purifying fan heats the whole room

At Dyson, we believe that a heater should warm you up wherever you are in the room. So we've built a testing environment that goes far beyond some other conventional fan heaters.

Dyson Engineer, David Hill, explains how we test and develop our fans, humidifiers and purifiers. Inspired by technology found in jet engines, Air Multiplier™ technology heats the room effectively without comprimising airflow performance.
