The Dyson BP04 is our quietest, most powerful, and advanced air purifier, engineered specifically to evenly purify large, open-plan spaces up to 100m² (1,080 ft²). It not only delivers powerful, long-range air projection to cool you but also detects and permanently destroys harmful formaldehyde.
Key features
Powerful whole-room purification
- Cone Aerodynamic Projection: Powerful, long-range projection circulates purified air and draws even distant pollutants back through the sealed filters.
- Acoustically Engineered: Designed to produce less noise, with an acoustically engineered motor bucket that enables quiet operation, even at full power.
- Breeze Mode: Mimics the feeling of refreshing, natural airflow indoors.
- Customizable Airflow: Adjust the angle of airflow between 0°, 25°, or 50° to suit your preference.
Advanced 3-stage filtration system
- HEPA H13 Grade Filter: Captures 99.97% of fine particles as small as 0.3 microns, including allergens, bacteria, and viruses. The large filter has a lifespan of up to 5 years.
- Exclusive K-Carbon Filter: Adsorbs up to three times more nitrogen dioxide (NO₂) than standard carbon filters. It is impregnated with potassium carbonate and lasts up to two years.
- Selective Catalytic Oxidization (SCO) Filter: Continuously traps and breaks down formaldehyde molecules into carbon dioxide (

) and water. This catalytic filter is permanent and never needs replacing.
Intelligent and connected
- Smart Sensors: Five advanced sensors, including a lifetime solid-state formaldehyde sensor, detect particles, volatile organic compounds (VOCs), and gases across the room.
- Automatic Response: A unique algorithm analyzes air quality data every second, automatically adjusting the purifier’s settings when pollutants are detected.
- Real-time Reporting: View live results on the integrated LCD screen or remotely via the MyDyson™ app.
- MyDyson™ App: Control your air quality from anywhere by monitoring pollutants, viewing reports, and setting purification schedules.
