Key features

Dyson Pure Hot+Cool purifier fan projecting clean air

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 99.97% of fine pollutants, and projects purified and heated air throughout your whole room. It is the only purifying heater designed and tested to do this.¹

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.³

Key technology

Automatically senses and reports particles and gases, in real time²

With three intelligent sensors, the Dyson Pure Hot+Cool™ purifier fan heater automatically detects airborne particles and gases

Captures pollutants you can’t see

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.

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.

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.

Powerful Air Multiplier™ technology

Air Multiplier™ technology delivers over 77 gallons of smooth, powerful airflow per second – circulating purified air throughout the whole room.¹

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.

Additional features

Heats in winter. Cools you in summer.

With long-range, purified heat projection it's quick to heat the whole room evenly.⁴

View temperature and air quality reports, fast

The Dyson Link app allows you to monitor the air quality in your home, and outdoors. Quickly check your machine's activity, past and present, as well as reports on temperature, humidity, and filter life.

Forward projection

Delivers a powerful stream of cooling, purified air from the front of the machine.

Diffused projection

The machine diverts air through the rear annular at a 45˚ angle, creating a more diffused airflow.

Oscillates up to 350˚

Adjustable oscillation angle from 45˚ to 350˚, to project purified air around the whole room.⁴

Voice control

Using a compatible voice service, control your machine with simple, spoken instructions.⁵

Frequently asked questions

How long should my purifying fan be turned on for?

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.

How do I know when my purifying fan heater is in 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.

Should I change the fan settings in different seasons?

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.
