The Dyson HEPA Big+Quiet Formaldehyde purifier is borne of Dyson’s longstanding expertise in airflow, acoustics, filtration and
compressors.

• Cone Aerodynamics: Dyson engineered airflow delivery system, offering more than double the airflow of previous Dyson purifiers, at up to 90 litres of airflow per second of purified air.
• CO2 sensor: Reports CO2 in real time, indicating to occupiers of shared spaces when to ventilate.
• Re-engineered motor bucket: Ensures quiet operation – meticulous re-engineering incorporating ingenious acoustic solutions including a Helmholtz cavity and labyrinth seal.
• Three-phase filtration system: Capturing up to 99.95% of ultrafine particles¹, removing odours and gases like NO2, Benzene and VOCs and permanently destroying formaldehyde².

1 Test completed in a 100 m2/1000ft2 (12.7m x 7.9m) room with the purifier placed in one corner and source of pollution in opposite corner. The room had 36 sensors to determine PM2.5 distribution and purification. Results may vary in practice..

2 Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
