Engineered for professional environments, the Dyson HEPA Big+Quiet Formaldehyde purifier is Dyson’s quietest, most powerful air purifier yet. Three phases of purification capture 99.97% of pollutants, as small as 0.3 microns and the machine is fully sealed to HEPA H13 standard.¹ The HEPA filter contains 69 feet of borosilicate microfibers, pleated over 450 times, and lasts 21,900 hours.² A selective catalytic oxidization filter works to destroy formaldehyde, continuously³, and an intelligent CO₂ sensor system senses and reports CO₂ levels in real time displaying results on the 1.44 inch LCD screen. Cone aerodynamics to 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.

Caveats:
1. Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150.
2. Filter life is determined by dividing total dust load capacity by annual dust load. Annual dust load was calculated using GB/T 18801 daily mass formula. Results may vary in practice.
3. Third 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.
