The Dyson Pure Hot + Cool is the only purifying heater + fan to clean a whole room properly.

We design our purifying heater + fans to go beyond test chamber conditions and focus on real home conditions – this is more than just having an efficient filter.

Dyson engineers and research concluded that to clean an entire room properly, you need to sense pollution events automatically; capture ultrafine pollutants; and project cleaner air around the room using Air Multiplier technology. Only the Dyson purifying heater + fan is designed and tested to do all of this.



  • MULTI-FUNCTIONALITY: Space Heater. HEPA Air Purifier. And Fan to help disperse the purified air throughout an area. In one. Backward airflow mode purifies without cooling or heating you.
  • SENSES: Automatically senses air pollution events, initiates purification, & reports air quality levels on LCD display, including ultrafine particles like dust (PM 2.5), allergens like pollen and mold (PM10), household odors and volatile organic compounds (VOCs) & by-products from car exhaust like Nitrogen Dioxide (NO2).
  • CAPTURES: The sealed HEPA filter captures 99.97% of allergens as small as 0.3 microns making this an ideal air purifier for allergies, pets, dust, smoke, pollen and mold spores. Activated carbon filter removes pollutants and household odors. 60x more HEPA media and 3x as much activated carbon than previous model.
  • PROJECTS: Projects purified air throughout the whole room. Air Multiplier™ technology delivers over 77 gallons per second of smooth, yet powerful airflow. Up to 350° of oscillation directs airflow where you need it to help make the air cleaner.

The AHAM AC1-2015 standard sets out how air cleaner manufacturers can define their performance by “the relative reduction of particulate matter suspended in the air in a specified test chamber” – this means their performance is based on cleaning efficiency rates only.

Tested to Dyson internal test method TM-003711 in a 290 sq. ft room and DTM801.

Based on a 2017 Dyson survey of self-reported allergy sufferers after use.
