Product Description

The Dyson Purifier Big+Quiet Formaldehyde BP04 is a powerful large-room air purifier engineered to deliver long-range purified airflow while operating quietly. Its advanced projection system can project purified air over 10 metres, helping create circulation throughout large spaces. Dyson has tested the purifier for spaces up to 100 m².

The fully sealed HEPA H13 filtration system captures 99.95% of ultrafine particles as small as 0.1 microns, helping remove allergens, dust and other airborne pollutants. The advanced K-Carbon filter captures gases and odours, while Dyson states that it captures 3 times more NO₂ than the standard carbon filter used in the earlier Big+Quiet Formaldehyde model.

The BP04 features a dedicated Selective Catalytic Oxidation (SCO) filter that continuously breaks down formaldehyde into water and carbon dioxide. Its solid-state formaldehyde sensor can detect formaldehyde molecules significantly smaller than 0.1 microns, allowing the purifier to monitor and respond to this pollutant automatically.

The purifier also monitors CO₂ levels in real time and provides detailed air-quality information. Through the MyDyson™ app, users can monitor air quality, control the purifier, set schedules and track filter life.

Finished in an elegant Prussian Blue/Gold colour combination, the BP04 is ideal for large living spaces and other areas where powerful, quiet air purification is required. It comes with a 2-year Dyson warranty.
