Three-stage HEPA H13, Activated carbon and SCO filtration captures particles, gases including NO₂, and destroys formaldehyde. All within a fully sealed HEPA machine. So what goes inside stays inside.⁷
Destroys formaldehyde, permanently⁵
A catalytic filter continuously traps and breaks down formaldehyde molecules into water and CO₂⁵. And it never needs replacing.
Fully-sealed to HEPA H13 grade⁶
Three phases of purification sit within our fully-sealed machine to trap pollutants inside, removing them from the air you breathe. Giving you reassurance that what goes inside, stays inside.⁶
Many indoor activities can emit pollution. Cleaning, decorating, cooking, even getting ready for work can produce airborne particles and gases.
-
VOCs from aerosols and cleaning products
Household cleaning sprays and disinfectants can release volatile organic compounds (VOCs).
-
Formaldehyde fumes from paints and glues
Formaldehyde is a potentially harmful gas released by some furniture, paints, glues, carpets and fabrics.
-
Cooking odours and combustion pollutants
Cooking doesn’t just leave lingering odours, it can also release pollutants like NO₂ when any fuel is burned. Which can build up in your home.
-
Pet odours, allergens and dander
Pets can bring unwanted allergens and odours into the home, which can stay in the air and settle on furniture.

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 particles², even in large spaces.¹ 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™ app⁵ – viewing in real-time the benefits of owning an air purifier.
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. 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 5 years.
The Dyson Purifier Big+Quiet Formaldehyde air purifier range is engineered to remove 99.95% of ultrafine particles², such as dust, allergens, odours, gases³ like benzene and nitrogen dioxide and even formaldehyde gas.⁴
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 five years or sooner. The Activated carbon filter should be replaced every two years, or sooner if required. 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.
-
Allergens
An allergen is a substance that can cause an allergic reaction by triggering the body’s immune system. Common indoor allergens include dust mite droppings, pet dander, mould, and pollen.
-
Bacteria
Microscopic, single-celled organisms that exist in their millions, in every environment. Not all bacteria are harmful, but some can have adverse effects, such as E. coli.
-
Benzene
Benzene is colourless, flammable liquid produced by both natural and man-made processes. It’s a natural part of crude oil, gasoline, and cigarette smoke. Indoors, it comes from products such as glues, paints, furniture wax, and detergents.
-
Carbon dioxide (CO₂)
A colourless greenhouse gas, which comes from the extraction and burning of fossil fuels. Increased CO₂ levels can impact cognitive function.
-
Formaldehyde
This colourless, flammable gas is used in some building materials and household products. Sources can include some fabrics found in flooring and furniture, glues, paints, varnishes, air fresheners, and household cleaners.
-
H1N1 virus
This subtype of Influenza A virus, also known as swine flu, caused a global flu outbreak. H1N1 produces respiratory infectious diseases in humans and pigs. Symptoms can be similar to seasonal flu.
-
HEPA 13
HEPA (High Efficiency Particulate Air) is an air filter efficiency standard and a measure of a filter’s performance. To achieve this standard, filters must meet a minimum of 99.97 per cent particle removal at the most penetrating particle size.
-
Humidification
A process of increasing air moisture content through the addition of water vapour or steam. Humidifiers can add moisture to the air in dry conditions, creating a more comfortable indoor environment when needed.
-
Microns
Airborne particles are usually described in microns. One micron is equal to one-millionth of a metre. The human eye can see debris and dust that are approximately 25 microns in size.
-
Nitrogen dioxide (NO₂)
Nitrogen dioxide is a liquid below 21.2 °C and a gas at higher temperatures. It is toxic to humans in both states. Gas stoves and space heaters are the most common indoor sources of NO₂ emissions. Other sources include improperly vented furnaces and water heaters.
-
Pet dander
Pet dander is made up of tiny particles of skin, saliva and urine, shed by animals with fur or feathers. Pet dander lingers in the air before settling on surfaces such as furniture, bedding, and fabrics. Exposure to these airborne particles can trigger allergies.
-
Particulate matter (PM)
Particulate matter contains microscopic solids or liquid droplets, measured in microns. Indoor PM can be generated through many day-to-day activities such as cooking, cleaning, and the burning of candles and fires.
-
Purification
The process of making something free of any contaminants or physical impurities. Air purification is designed to filter the air in your home – removing pollutants such as dust, allergens and viruses.
-
Volatile organic compounds (VOCs)
Volatile organic compounds are potentially harmful gases found in many household products. Common sources include paints, varnishes, air fresheners, cosmetics, and cleaning products.
-
Pollen
Pollen is a powdery substance released from seed plants as part of their reproduction process. It typically appears from trees in the spring, grasses in the summer, and weeds in the autumn. Pollen grains are among the most common allergens.
-
House dust mites
Dust mites are tiny insects that commonly live in household dust. They are one of the biggest causes of allergies. Each gram of house dust contains approximately 1000 dust mites.
-
Aspergillus mould
A common name for a visible group of fungi, mould thrives wherever there is dampness – sending out millions of spores into the air. Exposure to mould occurs via inhalation, skin contact, or ingestion.
