Homes can be up to 7X more polluted than the air outside3

Many household items – from decorating materials, to flooring, to plants – can release microscopic particles and gases. This includes formaldehyde, which can quickly build up and keep polluting for over a year.

Common household pollutants

  • Extreme close ups of harmful particles and gases, including formaldehyde.

    PM10

    Pollen and allergens

  • Extreme close ups of harmful particles and gases, including formaldehyde.

    PM2.5

    Industrial emissions

  • Extreme close ups of harmful particles and gases, including formaldehyde.

    PM0.1

    Ultrafine particles

  • Extreme close ups of harmful particles and gases, including formaldehyde.

    Gases and VOCs

    Cleaning products, gas stoves and car exhausts

Formaldehyde is 500X smaller than PM0.1

It's a potentially harmful chemical, emitted by numerous household products. It's particularly difficult to capture, and can pollute continuously.

Dyson Cryptomic™ technology destroys formaldehyde at a molecular level1

Dyson Cryptomic™ technology has a unique catalytic coating, with the same structure as the Cryptomelane mineral. Its billions of atom-sized tunnels are the optimal size and shape to trap and destroy formaldehyde, breaking it down into tiny amounts of water and CO2.

Automatically senses and reports particles and gases, in real time

With three intelligent sensors, the Dyson purifier fan automatically detects airborne particles and gases – including formaldehyde. The built-in LCD screen shows you which pollutants your machine has detected.4

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.

    Fan mode

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

  • A family relax as airflow diverts through the back of the fan in Diffused mode.

    Diffused mode

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