Filter technology

360° sealed filtration - captures gases and particulates.

360° Sealed filtration – captures gases and particulates The fully-sealed filter system combines an activated carbon filter to capture gases, and a Glass HEPA filter that captures 99.95% of microscopic allergens and pollutants as small as 0.1 microns.1

Glass HEPA filter.

9 metres of HEPA borosilicate microfibres, pleated over 238 times, to capture 99.95% of potentially harmful ultrafine particles.1

1 tested to EN1822. Particles as small as 0.1 microns.

Activated carbon filter.

Tris impregnated carbon granules capture gases such as formaldehyde, benzene and nitrogen dioxide.

Pollutants include:

 

PM 10

Pollen and allergens

PM 5.0

Bacteria and mould

PM 2.5

Industrial emissions

PM 0.1

Ultrafine particles

Formaldehyde

Odours and household fumes

Benzene

Nitrogen Dioxide

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

2 In max setting. Tested for filtration efficiency (EN1822) and whole room coverage (TM-003711 & DTM801) in a 27m2 room.

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.

Forward projection.

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

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.'
