The Dyson HEPA Big+Quiet Formaldehyde purifier is Dyson’s quietest, most powerful air purifier yet, engineered from the ground up, to evenly purify large spaces.² Cone aerodynamics create powerful jets of air to project purified air around the room, and the purifier is acoustically engineered to operate at lower noise levels of just 55.6dBA at its highest power setting. An advanced 360 HEPA H13 grade filter¹ captures allergens and 99.97% of fine particles. Removes gases and odors.⁶ Destroys formaldehyde, permanently.³ *Product is intended for commercial use only.
¹Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode, for whole machine efficiency above 99.95%.
²Testing for PM2.5 purification completed in a large testing chamber following relevant Dyson testing methods. Results may vary in practice.
³Third party full machine testing based on GB/T 18801-2022 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
⁴Filter life calculated using GB/T 18801 daily mass formula, and is based on 12 hours use per day. Results may vary in practice.
⁵Levels defined by Dyson based on scientific literature (Lowther et al. (2021)Environments). Ventilation alert when CO2 levels are 1500ppm or above.
⁶Tested to JEM 1467 (acetic acid, acetaldehyde, ammonia), GB/T18801 (formaldehyde, benzene) and DTM-003283 (NO2). Gas capture rates vary.
