Big+Quiet Formaldehyde™ HEPA air purifier

Designed for large spaces, Big+Quiet Formaldehyde activates automatically according to the pollutant level it captures, notably through its HEPA 13 filter, which according to Dyson can trap pollutants as small as 0,1 micron.
Big+Quiet is said to capture formaldehyde, a pollutant gas found particularly in varnishes, glues and paints.
A new CO27 sensor equips the air purifier and tells users when the air needs cleaning based on pollutant levels. To do this, Purifier Big+Quiet Formaldehyde analyses air quality every second and decides whether to start purification.
