-
Automatic sensing
Reacts automatically to detect, track and capture common household pollutants, only using energy when necessary.
-
Fully-sealed HEPA filtration
Whole-machine fully-sealed filtration to HEPA H13 standard. So the pollution captured inside stays inside.³
-
Long-range air projection
Cone aerodynamics and Air Multiplier™ technology circulate purified air throughout the whole room.⁴
Key features and technology
-
Ceramic plates for fast room heating
Positive temperature coefficient ceramic plates heat the air as it’s projected. For fast, even room heating⁵ using less energy than standard convection heaters.
-
Powerful airflow to cool you quickly
Use Focus or Fan mode to channel a narrow jet of air for fast, powerful cooling. Or try Diffused mode to mimic a summer breeze and purify quietly using less energy.
-
Exclusive Air Multiplier™ technology
Combines technologies used in turbochargers and jet engines to amplify airflow up to 15 times.⁶ For powerful cooling and fast, long-range air projection.
-
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.

How air purifiers can help reduce your allergens in your home
As our homes become increasingly well sealed, it may seem like we’re shutting allergens out. But instead, we're shutting them in. Dyson air purifiers capture pollen, pet dander, mould spores and dust particles, removing them from the air so you can breathe cleaner air at home.
- 1 In maximum setting. Tested for air projection, purification coverage in a 81m³ room.
- 2 Third party full machine testing based on GB/T 18801-2018 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
- 3 Tested for filtration efficiency at 0.1 microns (EN1822). Gaseous capture rates vary.
- 4 Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
- 5 In maximum setting. Tested for air projection, purification coverage in a 81m³ room.
- 6 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463).
- 7 Compared to fan speed 10
- 8 We challenged our purifier with airborne influenza A (H1N1 virus) at an independent lab. After 60 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99%. Real-life efficacy may vary.
