Dyson Pure Cool Filter close up capturing pollutants

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 99.97% of microscopic allergens and pollutants as small as 0.3 microns.

Dyson Pure Cool Glass HEPA borosilicate fibers close up

Glass HEPA filter.

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

Dyson Pure Cool carbon filters captures gases magnified

Activated Carbon filter.

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

Potentially harmful, particles and gases can be found throughout the home, these include…

  • PM 10

    Pollen and allergens
    from plants and flowers

  • PM 5.0

    Bacteria and
    mold
     

  • PM 2.5

    Industrial
    emissions

  • PM 0.3

    Ultrafine particles
    and viruses

  • Formaldehyde

    Carpets, rugs
    and flooring

  • Odors

    Household fumes
    and cooking

  • Benzene and VOCs

    Cleaning products
    and scented candles

  • Nitrogen Dioxide

    Gas stoves and
    car exhausts

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. 

Dyson Pure Cool sensor close up

Particulate sensor
Uses laser measurement for constant particulate concentration analysis.

Gas sensor
Detects Volatile Organic Compounds (VOCs) and oxidizing gases such as NO2.

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

Airflow projecting from a Dyson Pure Cool™ purifying fan

Powerful Air Multiplier™ technology.

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

Dyson Pure Cool two airflow modes

Two airflow modes.

An air valve mechanism is driven by a brushless stepper motor, to allow remote actuation and switching between Backward airflow 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 place to deliver a forward powerful stream of purified air. 

  • Backward 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 'draft.'
