Testing standards

Dyson engineers go further during testing. Our uniquely designed POLAR test ensure Dyson air purifier fans are capable of whole-room filtration.

The industry-wide CADR test

Some air purifier and humidifier manufacturers test performance with a lab test method called ‘Clean Air Delivery Rate’ (CADR). Conducted in a compact chamber measuring just 28.5m³, air quality is measured with only one sensor.

In real homes, filtration quality matters. If particles aren’t captured first time, they are released back into the home. Unlike real homes, the CADR test is conducted for 20 minutes in a small chamber, tracking just the speed of filtration, rather than the quality.

  • 28.5m³

    Small test chamber (with fans on the ceiling and walls to help circulate the air)
  • 1 sensor

    That maps and monitors how the chamber is purified for only 20-25 minutes
  • 3 particles

    removed: dust, pollen and tobacco smoke

The Dyson POLAR test

Dyson air purifier fans are engineered to work in real homes. That’s why we developed our POLAR test. Based on a larger room size of 81m³, nine different sensors continually collect air quality data throughout the entire room. Ensuring purified air is evenly distributed to every corner.

Ultrafine particles are suspended in the air we breathe

Filtration quality is crucial. Particles at 2.5 microns measure just 1/30th the size of a human hair. Ultrafine particles at 0.1 microns fit 1,000 times across the diameter of a human hair. Dyson purifiers capture 99.95% of particles as small as PM 0.1*.

Our rigorous test methods tell us more

  • Dyson purifier in testing situation

    Full grid test

    Measures air flow, velocity and direction from the purifier. Good circulation helps prevent dirty air from lingering in some areas of the room.

  • HEPA filter ingesting gasses

    Dyson HEPA filtration efficiency test

    Some purifiers release dirty air back into the room. We test our HEPA filters to capture 99.95% of particles as small as PM 0.1.

  • Image of harmful pollutants around the home

    Gaseous pollutants

    Potentially harmful gases can be emitted from cookers, new furniture, naked flames and cleaning products. We test that our purifiers capture these.

  • Dyson purifier in acoustic chamber

    Acoustics testing

    We invest in sound power and sound quality analysis, to develop night-mode settings that enable air purification without disturbing you.

"Dyson has been filtering air for more than 25 years. Our engineers ensure our machines capture more potentially harmful ultrafine particles and gasses in real homes, than conventional lab testing."
