Bring powerful air purification to larger living spaces with the Dyson Purifier Big+Quiet Formaldehyde BP04 in Prussian Blue/Gold. Its sealed three-stage filtration system captures airborne particles and gases, while a dedicated catalytic filter continuously breaks down formaldehyde. Automatic sensing, adjustable airflow and MyDyson app control make it easy to monitor your indoor air and adapt purification to your daily routine.
Features
Three-stage purification: HEPA H13-grade, K-Carbon and Selective Catalytic Oxidisation filtration work together to capture particles and gases within a sealed machine.
Fine-particle capture: the HEPA H13 filter captures 99.95% of particles as small as 0.1 microns under Dyson's stated testing conditions, including airborne dust and allergens.
Continuous formaldehyde destruction: a solid-state sensor detects formaldehyde, and the catalytic filter breaks it down into small amounts of water and carbon dioxide.
Enhanced gas filtration: the K-Carbon filter captures nitrogen dioxide and other gases. Dyson reports three times more NO₂ adsorption than the standard carbon filter in its BP03 model.
Long-range airflow: cone aerodynamics projects purified air over 10 metres at maximum directional airflow, helping circulate air across larger spaces.
Airflow to suit your comfort: select 0°, 25° or 50° projection, or use Breeze mode for varying airflow.
Automatic air-quality monitoring: Auto mode responds to detected pollutants, with real-time information available on the LCD screen and in the MyDyson app.
CO₂ awareness: a dedicated sensor reports elevated carbon dioxide levels and alerts you when ventilation is needed.
Convenient daily control: use the included magnetic remote or the MyDyson app to adjust your purifier, review air-quality reports and set schedules. App functions may vary by market.
Designed for quieter use: acoustically engineered operation, Night mode and a sleep timer support comfortable use throughout the day and evening.
Easy movement on hard floors: discreet wheels help reposition the purifier around your room.
