The Dyson Purifier Big+Quiet Formaldehyde BP04 is a high-performance air purifier engineered for large spaces, combining advanced filtration, formaldehyde destruction and ultra-quiet operation. It is designed to project purified air over long distances while maintaining low noise levels for continuous use.
At its core, the unit features a fully sealed HEPA H13 filtration system, combined with an activated carbon filter, capable of capturing 99.95% of ultrafine particles as small as 0.1 microns, including dust, allergens, bacteria and airborne pollutants.
The purifier also includes a solid-state catalytic filter that continuously destroys formaldehyde, converting it into water and carbon dioxide. This filter is permanent and does not require replacement, ensuring long-term performance without additional maintenance.
The BP04 is designed with Cone Aerodynamics technology, which delivers powerful long-range airflow projection of up to approximately 10 meters, allowing purified air to circulate effectively throughout large rooms such as open-plan living areas, offices or commercial spaces.
Despite its powerful performance, the appliance is engineered for quiet operation, producing minimal noise even at higher airflow settings, making it suitable for use in environments where low sound levels are important.
The unit features advanced sensing technology, with integrated sensors that continuously monitor air quality, detecting pollutants such as particulate matter (PM2.5, PM10), volatile organic compounds (VOCs) and formaldehyde. Real-time data is displayed on the integrated LCD screen.
The BP04 offers multiple airflow modes, including:
-
Auto mode – automatically adjusts purification based on detected air quality
-
Diffused mode – purifies air without cooling airflow
-
Fan mode – provides cooling airflow while purifying
It also supports wide-angle oscillation, enabling even distribution of purified air across large areas.
The purifier can be controlled via the Dyson Link app, allowing users to monitor air quality, adjust settings and schedule operation remotely. It is also compatible with voice control systems.
