DysonBig and Quiet Formaldehyde Purifier (Model: BP04)

About

The Dyson Purifier Big+Quiet Formaldehyde BP04 is a high-capacity air purifier designed for large living spaces. It projects purified air across long distances (over 10 metres) while running quietly. It features advanced filtration that not only captures ultrafine particles, gases and odours, but also destroys formaldehyde and includes a CO₂ sensor for indoor air quality monitoring. It’s engineered for rooms where performance, coverage and minimal noise matter.

Product Features

• Projects purified air up to approximately 32 feet / 10 metres for large-space coverage.
• Cone aerodynamics system that delivers a strong air throw while keeping noise low.
• Captures ~99.97% of fine particles as small as 0.3 microns.
• Fully-sealed HEPA H13-grade filtration system so that captured pollutants do not leak back into the room.
• New K-Carbon filter layer that captures around 3× more nitrogen dioxide (NO₂) than previous carbon filters.
• Selective Catalytic Oxidation (SCO) filter element specifically designed to destroy formaldehyde rather than simply trap it.
• Integrated CO₂ sensor to alert when ventilation is required.
• Adjustable airflow projection angles: 0°, 25°, or 50° for directing clean air across a room.
• Smart sensors + algorithm that monitor particles, gases, formaldehyde and CO₂ in real time; automatic fan speed adjustment.
• Quiet at full power: engineered motor bucket and acoustic design produce around 56 dB(A) of sound power at max speed.
• Wi-Fi/app control (MyDyson™ app) plus remote control for live monitoring of air-quality data, filter life and scheduling.
