Discover the air pollutants commonly found inside homes
Allergens, pollen and airborne mould spores
Allergy season can be difficult. The Dyson Purifier Big+Quiet reduces your exposure to allergens, such as pollen and airborne mould spores. 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 99.9% of viruses.6
Pet odours, allergens and dander
Pets can bring unwanted odours and allergens into the home. Dogs and cats shed dander, releasing microscopic skin, saliva and urine allergens into the air.
Cooking odours, pollutants and nitrogen dioxide
Cooking or burning any type of fuel can release odours and potentially harmful pollutants like NO2. The Dyson Purifier Big+Quiet is 30% faster at reducing cooking odours by 97%.11
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, mould spores and bacteria.
Formaldehyde fumes from paints and glues
Formaldehyde is a potentially harmful gas released by some furniture, paints and fabrics. Often present in small amounts, concentrations can increase when decorating.
VOCs from aerosols and cleaning products
Some household products like disinfectants and aerosols can release potentially harmful gases into the air. These are known as volatile organic compounds (VOCs).
More time indoors can mean more exposure to pollutants
During the colder months, we spend more time indoors, use more heating, and ventilate less often, which can make the air at home more polluted.

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 MyDyson™ app.10
Our most advanced filtration system
HEPA-H13, K-carbon and SCO filtration captures particles and gases including formaldehyde – within a fully sealed machine. So what goes inside, stays inside.12
Exclusive K-carbon filter
Impregnated with potassium carbonate, it adsorbs three times more NO2.² Removing a common and potentially harmful pollutant. And lasts two years.⁹
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.3 Or cool you when required.
Frequently asked questions
The Dyson Purifier Big+Quiet Formaldehyde is our quietest, and most powerful air purifier. Using cone aerodynamics to deliver powerful, long-range air projection – circulating purified air and driving even distant pollutants back through sealed filters. For whole-room purification – capturing 99.95% of ultrafine particles,⁵ even in large spaces.³ You can control your air quality, wherever you are. At the touch of a button you can monitor the air quality levels in your home using the MyDyson™ app – viewing in real-time the benefits of owning an air purifier.10
Not all purifiers are equal. Getting the right size purifier, with the best projection is essential to ensure it will effectively purify the air in your space. We've tested the Dyson Purifier Big+Quiet Formaldehyde extensively – to ensure the sensors, filtration system and motor work together to purify a large living space. It has the projection power to purify spaces up to 100m².³ The Dyson Purifier Big+Quiet Formaldehyde also has our largest ever filtration system – and the 360° HEPA H13-grade filter doesn’t need replacing for up to 11 years.9
The Dyson Purifier Big+Quiet Formaldehyde air purifier range is engineered to remove 99.95% of ultrafine particles,5 such as dust, allergens, odours, gases4 like benzene and nitrogen dioxide and even formaldehyde gas.8
The Dyson Purifier Big+Quiet Formaldehyde has our most advanced filtration system. We recommend replacing the 360° HEPA H13-grade filter after using it for up to 11 years or sooner. The exclusive K-carbon filter should be replaced every two years, or sooner if required.9 The Selective Catalytic Oxidisation (SCO) filter is permanent and never needs replacing.
The Dyson Purifier Big+Quiet Formaldehyde has been designed to work from the corner of a room, at least one metre away from the wall. For optimal performance we recommend projecting air either along a wall or across the room. You can adjust the angle of projection to suit your preference.
The Dyson Purifier Big+Quiet Formaldehyde has discreet wheels, which aren’t visible when the machine is upright. These wheels are designed for hard floors – so you can move your purifier around easily.

1The ability of purifying a large room up to 100m2 (10m*10m) proven from a Computational Fluid Dynamics (CFD) modelling, with the purifier placed in a corner of the room running at the maximum flow and horizontal projection reaching 10 metres to fully mix the room. The projection distance was measured from internal flow reach testing under the maximum directional airflow. The actual performance in real life condition may vary.
2Tested for filtration efficiency at 0.1 microns (EN1822, ISO29364).
3Tested to JEM 1467 (acetic acid, acetaldehyde, ammonia), GB/T18801 (formaldehyde, benzene) and DTM-003282 (NO2). Gas capture rates vary.
4Compared to adsorption by the standard carbon filter in Dyson Purifier Big+Quiet Formaldehyde (BP03).
