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 up to a year.

Some air conditioning units may trap and circulate pollutants8

Dyson purifiers capture them and project clean air.

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

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

    PM5.0

    Bacteria and mould spores

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

    Benzene and VOCs

    Cleaning products and scented candles

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.

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.
