Dyson Big + Quiet Formaldehyde Purifier

The Dyson Purifier Big+Quiet Formaldehyde (BP04) is Dyson’s largest and most powerful purifier, engineered specifically for large, open-plan spaces. Using innovative Cone Aerodynamics, it projects powerful airflow over long distances while operating quietly. This unit features advanced **HEPA H13 and Selective Catalytic Oxidation (SCO)** filtration to capture ultrafine particles and permanently destroy formaldehyde. It is finished in a premium Prussian Blue/Gold. 

Key Features:

• Powerful Long-Range Projection: Utilizes Cone Aerodynamics to project powerful, purified air over 10 meters, effectively circulating clean air throughout very large rooms.
• Big Yet Quiet: Engineered acoustically to operate quietly, delivering strong airflow with a maximum sound level of just 56 dB.
• Formaldehyde Destruction: The Selective Catalytic Oxidation (SCO) filter continuously and permanently breaks down formaldehyde molecules into water and never needs replacing.
• Whole-Machine HEPA Filtration: A massive HEPA H13 and Activated Carbon filter captures 99.95% of ultrafine particles, pollutants, and Oduors.
• Intelligent Sensing: Monitors five key air pollutants (including Formaldehyde, PM2.5, and VOCs) and displays air quality data in real-time on the large integrated LCD screen.
