Dyson, aeronautics and air purification

The Big+Quiet model uses the HushJet nozzle, a technology inspired by aeronautics through which Dyson aims to control both airflow and acoustic turbulence simultaneously. A low-pressure, high-flow compressor drives air through a three-stage filtration system that captures particles and gases and breaks down formaldehyde. There is also the Dyson HushJet Pure Cool+ Formaldehyde, the mid-sized version of the new HushJet platform. Dyson claims it has up to three times the purification capacity of previous models, with an airflow designed to push clean air deeper into the room.
