Key features

Heats, cools and purifies

To simultaneously purify and heat a whole room properly, the Dyson Pure Hot+Cool™ purifier fan heater goes beyond standard tests. Using Air Multiplier™ technology, it automatically senses pollution, captures 99.95% of ultrafine pollutants,3 and projects purified and heated air throughout your whole room. It is the only purifying heater designed and tested to do this.

Pollutants can build up inside your workspace. But you can't always see them.

In fact, indoor air quality can be up to 5x worse than outdoor air quality.4

    Fast, safe, efficient heating

    Self-regulating ceramic plates are positioned at the front of the amp, to heat the air as it leaves the machine.

  • X-ray of the thermostat control

    Once your target temperature is reached, the machine automatically stops heating, which saves energy. If the temperature starts to drop, it reactivates to maintain it.

  • Graphic of Air Multiplier technology

    Powerful Air Multiplier™ technology

    Air Multiplier™ technology delivers over 290 litres of smooth, powerful airflow per second – circulating purified air throughout the whole room.

  • X-ray of two apertures of the Air Multiplier technology

    Two airflow modes

    The machine has two separate apertures, to release air from either the front or back of the machine. The valve mechanism turns a rotational baffle around the arc of the amplifier, to switch the direction of the airflow.

Frequently asked questions

Your purifying fan's auto mode is designed to manage the air quality without you having to operate the machine – so it's only on when it needs to be. If someone is suffering from allergies or respiratory illnesses, we particularly recommend using your machine's auto mode.

If auto mode is enabled, AUTO will be illuminated on your purifying fan's LCD display. When your machine is purifying the air, AUTO will be in white. When the air in the room is purified, it will turn green and your purifying fan heater will remain idle until pollutant levels rise.

Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your purifying fan heater's speed settings as the temperature changes. For personal cooling in summer, use settings 4-10. In colder periods, enable diffused mode. It projects air through the back of the machine, to avoid unwanted cooling.
