Dyson Pure Cool Filter technology

360° sealed filtration – removes gases and particulates.

The fully-sealed filter system combines an activated carbon filter to remove gases, and a Glass HEPA filter that captures 99.95% of microscopic allergens and pollutants as small as 0.1 microns.¹

Using a unique algorithm, the Dyson Pure Cool™ purifying fan processes the input from three sensors to continually monitor the room air quality.

It uses this information to activate the machine and keep room pollution levels low.

Particulate sensor
Uses laser measurement for constant particulate concentration analysis.

Nitrogen Oxide sensor
Detects Volatile Organic Compounds (VOCs) and oxidising gases such as NO2.

Humidity and temperature sensor
Constantly monitors the relative humidity and temperature levels within the room.

Powerful Air Multiplier™ technology.

Air Multiplier™ technology delivers over 290 litres per second of smooth, yet powerful airflow –circulating purified air throughout the whole room.²

Dyson Pure Cool delivering 290 liters of powerful airflow per second

Two airflow modes.

An air valve mechanism is driven by a brushless stepper motor, to allow remote actuation and switching between Diffused mode and Fan mode. The stepper motor drives a pinion gear, which turns a rotational baffle driver around the arc of the amplifier. Angled slots in the baffle driver move the baffle forwards and backwards.

Dyson Pure Cool two airflow modes

Forward projection

The baffle stays in plays to deliver a forward powerful stream of purified air.

Dyson Pure Cool diffused projection breakdown

Diffused projection

The baffle moves to block the front aperture and diverts air through the rear of the annular at a 45° angle, creating a more diffused airflow. This uses less energy and is quieter because the aperture is wider. Purification effectiveness is still maintained, without the 'draught.'
