We test beyond the industry standard. For real living spaces.

Dyson engineers designed the POLAR test to challenge the industry test standard – measuring filtration, sensing and circulation to ensure the whole room is purified properly.

  • CADR測試與 Dyson 測試圖比較圖

    CADR is not a measure of purification performance in a real-size room

    28.5m³ - Two additional fans boost circulation. Only one sensor measures air quality.

  • CADR測試與 Dyson 測試圖比較圖

    Dyson's POLAR test goes further to measure purification throughout a real-size room

    81m³ - No additional fans. Nine different sensors to measure even-room air quality.

Destroys formaldehyde in billions of catalytic tunnels¹

Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO2. And it self-regenerates, so it never needs replacing.

The purifier is fully sealed to HEPA H13 standard

To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier4. So what goes inside, stays inside.
