Dyson Big+Quiet Formaldehyde Air Purifier 410624-01

Large rooms need serious airflow, but they shouldn't come with a side of background noise. The Big+Quiet Formaldehyde air purifier is engineered for open-plan living and high-ceiling spaces, using a clever aerodynamic cone to project a jet of clean air over 10 metres. It doesn't just trap pollutants — it actually destroys formaldehyde and captures 99.97% of allergens and gases, all while running so quietly you’ll forget it’s even in the room.
