It uses Cone Aerodynamics to deliver 10-metre projection, a new K-Carbon filter for better NO2 capture and introduces a CO2 sensor. Cone Aerodynamics uses the Coanda effect to merge two streams of air over a smooth surface, resulting in a powerful and condensed jet of air that can be projected of up to 10 metres – more than double the airflow of the previous generation Dyson Purifiers – with minimal noise.

Alongside its powerful projection, the Dyson Purifier Big+Quiet Formaldehyde is also engineered to operate quietly, producing just 56 decibels of noise – making it Dyson’s quietest yet most powerful purifier. For comparison, a quiet library produces around 40 decibels of noise.

With haze season coming, an air purifier might be the best thing to get to prevent getting respiratory diseases. The Dyson Purifier Big+Quiet Formaldehyde does not come cheap though, with pricing starting from S$1,299.
