The Dyson Pure Cool™ purifier – Overview

Explore the Dyson Pure Hot+Cool

Advanced purification and even room heating

360˚ sealed filtration. Removes gases and pollutants.

Made with 9 metres of borosilicate microfibres, pleated over 200 times. It removes 99.95% of allergens and pollutants as small as 0.1 microns.1

Glass HEPA filter

9 meters of borosilicate microfibers, pleated over 238 times, to capture 99.97% of particles as small as 0.3 microns.

Activated carbon filter

Engineered using a dense layer of carbon crystals, and treated with oxygen to make it more porous. This increases the carbon's surface area, further helping to trap gases – such as formaldehyde, benzene and NO2.

Continually monitors air quality, and reacts

The Dyson Pure Hot+Cool™ purifying fan heater has three intelligent sensors to monitor what's
in the air. Using a unique algorithm, it processes the input to provide real-time indoor air quality reports.

When purifiers and heaters don't distribute air through the room, areas can be left unheated and polluted. Dyson purifying fan heaters mix and circulate the air, so they heat and purify the whole room evenly.2

Some purifiers and heaters only treat the air surrounding them

Dyson Pure Hot+Cool™ heats and purifies the whole room.2


Fast, safe, efficient heating

Positive Temperature Coefficient plates

Self-regulating ceramic plates are positioned at the front of the amp, to heat the air as it leaves the machine.
As the plates heat up, they conduct less electricity to help ensure they don't overheat.

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 290 litres of smooth, powerful airflow
per second – circulating purified air throughout the whole room.3

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.


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.
