Dyson Purifier Big+Quiet Formaldehyde

Advanced 360° Filtration System — Three phases of purification sit within a fully-sealed machine. The re-engineered HEPA H13 grade filter is 3.8x larger than its predecessor and captures 99.95% of ultrafine particles. An activated carbon filter captures gases such as benzene and NO₂, while the selective catalytic oxidisation filter traps and breaks down formaldehyde into CO₂ and water.

Destroys Formaldehyde, Permanently — Dyson’s solid-state formaldehyde sensor detects molecules 500 times smaller than 0.1 microns. The unique catalytic filter breaks down formaldehyde into water and CO₂, permanently removing it from your air.

Quiet, Even at Full Power — Acoustically engineered to run quietly at maximum power, this purifier continually reduces your exposure to pollutants without disturbing your home environment.

Adjust Your Airflow — Choose airflow angles of 0°, 25°, or 50°, or activate Breeze mode to simulate natural, refreshing airflow indoors.
