Dyson Big+Quiet Formaldehyde Air Purifier BP04 Prussian Blue-Gold (Hong Kong) Advanced 360° filtration system: Three phases of purification sit within a fully-sealed machine. Our re-engineered HEPA H13 grade filter is 3.8x larger than its predecessor and captures 99.95% of ultrafine particles. Our activated carbon filter captures gases such as benzene and NO₂ from your environment. And the selective catalytic oxidisation filter traps formaldehyde in catalytic tunnels, continuously breaking it down into CO₂ and water. Destroys formaldehyde, permanently: Dyson's solid-state formaldehyde sensor works to detect formaldehyde molecules 500 times smaller than 0.1 microns. Dyson's unique catalytic filter breaks the formaldehyde molecules apart, leaving only tiny amounts of water and CO₂ in the air, destroying the formaldehyde permanently. Quiet, even at full power:Acoustically engineered to operate quietly - even at its highest power setting. So it continually reduces your exposure to pollution, without disturbing you around the home. Adjust your airflow : Adjust the angle of airflow at 0°, 25° or 50°, or mimic the feeling of refreshing air indoors using Breeze mode.
