The Dyson Purifier Big+Quiet Formaldehyde (BP03) is a high-performance, commercial-grade air purification system re-engineered for expansive residential spaces. Moving away from traditional tower shapes, this unit uses aerodynamics to project clean air over 10 metres (32 feet), ensuring complete and even air distribution in rooms up to 100 m² (1,000 sq ft). True to its name, it accomplishes this while keeping sound levels incredibly low—producing a mere 43 dBA of operational noise even at high speeds.
Key Features
Our quietest, most powerful purifier. For a healthier home environment.
Purifies any room - including large, open-plan spaces. Captures pollutants, allergens* and odors, yet does it quietly.
Air pollution isn’t just outside – it’s inside too
Advanced automatic sensing technology
Dyson air purifiers automatically diagnose air quality - sensing and capturing airborne particles, and displaying real-time air quality reports on your LCD screen or MyDyson app.
Allergens and pollen
Allergy season can be difficult. The Dyson Purifier Big+Quiet reduces your exposure to allergens, such as pollen. For cleaner indoor air.
Bacteria, viruses and microscopic particles
Bacteria and viruses can spread more easily when we spend more time together indoors. The Dyson Purifier Big + Quiet is proven to capture viruses.
Pet odors, allergens and dander
Pets can bring unwanted odors and allergens* into the home. Dogs and cats shed dander, releasing microscopic skin, saliva and urine allergens* into the air.
Cooking odors, pollutants and nitrogen dioxide
Cooking or burning any type of fuel can release odors and potentially harmful pollutants like NO:, which can build up in your home.
Household dust and airborne particles
Household dust is a complex mixture of microscopic particles, including dead skin cells, dust mites, dust mite droppings, small insects, pollen, smoke, and bacteria.
Quietly purifies, even at full power
Our quietest purifier is acoustically engineered to produce less noise. With Night mode that’s 50% quieter than any other Dyson purifier.
Powerful projection to cool you in summer
Cone aerodynamics for powerful, long-range air projection. Delivers more than 21 gallons of purified air per second. To cool you and purify the whole room.
Hygienic filter replacement

Discover the pioneering technology inside
Our most advanced suite of sensors
A suite of sensors interact with our unique algorithm, cross-checking pollution data every second and reporting live results onscreen or the MyOyson™ app.
Advanced three-stage filtration system
HEPA-H13, Activated carbon, and SCO filtration captures particles and gases including formaldehyde - within a fully sealed machine. So what goes inside, stays inside.
Activated carbon filter
Removes odors and volatile organic compounds (VOCs)2 like benzene, as well as gases such as N02 - a common and potentially harmful pollutant.
Cone aerodynamic projection
Drives high-velocity air jets over the machine's dome, which coalesce to project a focused stream of air. To purify large spaces quietly. Or cool you when required.
