The Dyson Purifier Big+Quiet Formaldehyde BP03 is a high-performance air purifier designed for large indoor spaces, combining advanced filtration, powerful airflow projection and quiet operation. It is engineered to maintain clean air across wide areas such as open-plan living rooms, offices and commercial environments.
The purifier features a fully sealed multi-stage filtration system, including:
-
HEPA H13 filter – captures up to 99.95% of ultrafine particles as small as 0.1 microns, including dust, allergens and bacteria
-
Activated carbon filter – removes gases, odors and harmful pollutants such as VOCs and nitrogen dioxide (NO₂)
-
Selective Catalytic Oxidation (SCO) filter – continuously destroys formaldehyde, breaking it down into water and CO₂ without needing replacement
The BP03 is equipped with advanced sensing technology, enabling real-time monitoring of indoor air quality. It detects:
- PM2.5 and PM10 particles
- Volatile organic compounds (VOCs)
- Nitrogen dioxide (NO₂)
- Formaldehyde
The purifier automatically adjusts its performance based on detected pollution levels, while displaying live air quality data on the unit and via the MyDyson™ app.
A key feature is Cone Aerodynamics technology, which produces a powerful, focused airflow capable of projecting purified air across distances of up to 10 meters, ensuring effective circulation in large rooms.
Despite its powerful airflow, the BP03 is engineered for quiet operation, making it suitable for continuous use in living spaces, bedrooms or offices.
The device offers multiple operating modes:
-
Auto mode – automatically optimizes purification based on air quality
-
Fan mode – provides a cooling airflow effect
-
Diffused mode – purifies air without direct airflow
Additional features include wide-angle oscillation, remote control and smart connectivity for convenient control and monitoring.
