It's our business to understand air pollution, so yours doesn't suffer

Workspaces can harbour pollutants such as viruses, bacteria, Volatile Organic Compounds (VOCs), pollen and formaldehyde. Everyday items such as cleaning products and printers, furniture and flooring, can release potentially harmful microscopic particles, and remain in the air for many years.3

A large living space and the sources of various pollutants.

Dyson purifiers remove these common pollutants from commercial environments

  • Paint, varnishes and printers

    Formaldehyde

  • Traffic, building materials and furniture

    Benzene and VOCs

  • Fumes and cooking

    Odours

  • Pollen, dust and allergens

    PM10

  • Bacteria and mould

    PM5

  • Ultrafine particles

    PM0.1

Engineered to purify large spaces

Fully-sealed to HEPA H13 standard to capture 99.95% of pollutants as small as 0.1 microns.4 Purifying rooms up to 100m², evenly.1

Senses, captures and destroys

  • The conic amplifier top section of the purifier.
    Senses and reports CO2 levels

    1.44 inch LCD screen displays carbon dioxide readings and airflow mode – senses and reports air quality levels in real time.

  • The filtration system within the Dyson purifier.
    Whole-machine HEPA 13 filtration2

    Three phases of purification draw pollutants in from all directions. And the whole machine is fully sealed to HEPA H13 standard – so what goes in, stays in.

  • A formaldehyde molecule.
    Destroys formaldehyde, continuously3

    The solid-state formaldehyde sensor works simultaneously with a selective catalytic oxidisation filter, to destroy formaldehyde molecules 500x smaller than 0.1 microns.

Powerful and quiet

The high-velocity, low-pressure system produces low noise levels of just 55.6dB.

Acoustically engineered

The Helmholtz silencer traps sound energy and reduces low frequency noise, while the motor mount reduces vibration – so the little noise you hear, is quiet even at full power.

  • Activated carbon filter

    430,000m² of activated carbon captures microscopic particles, and lasts 8,760 hours.
