It's our business to understand air pollution, so yours doesn't suffer
Workspaces can harbour pollutants such as viruses, bacteria, Volatile Organic Compounds (VOCs), pollen and formaldehyde. Everyday items such as cleaning products and printers, furniture and flooring, can release potentially harmful microscopic particles, and remain in the air for many years.³
Dyson purifiers remove these common pollutants from commercial environments
-
Paint, varnishes and printers
Formaldehyde
-
Traffic, building materials and furniture
Benzene and VOCs
-
Fumes and cooking
Odours
-
Pollen, dust and allergens
PM10
-
Bacteria and mould
PM5
-
Ultrafine particles
PM0.1
Engineered to purify large spaces
Fully-sealed to HEPA H13 standard to capture 99.95% of pollutants as small as 0.1 microns.⁴ Purifying rooms up to 100m², evenly.¹
Senses, captures and destroys
-
Senses and reports CO₂ levels
1.44 inch LCD screen displays carbon dioxide readings and airflow mode – senses and reports air quality levels in real time.
-
Whole-machine HEPA 13 filtration²
Three phases of purification draw pollutants in from all directions. And the whole machine is fully sealed to HEPA H13 standard – so what goes in, stays in.
-
Destroys formaldehyde, continuously³
The solid-state formaldehyde sensor works simultaneously with a selective catalytic oxidisation filter, to destroy formaldehyde molecules 500x smaller than 0.1 microns.

Powerful and quiet
The high-velocity, low-pressure system produces low noise levels of just 55.6dB.

Acoustically engineered
The Helmholtz silencer traps sound energy and reduces low frequency noise, while the motor mount reduces vibration – so the little noise you hear, is quiet even at full power.

Frequently asked questions
Our latest purifier is acoustically engineered to operate quietly – even at its highest power setting. So it reduces your exposure to pollution, without disturbing you at the office or in the classroom. It records just 55dBA of sound power at full speed.
In Dyson’s latest purifiers, it’s not just the filter that meets HEPA H13 standard, it’s the whole purifier. So they don’t just capture pollutants, they prevent them from leaking back into the air you breathe. High-pressure seals at 24 critical points, combined with Dyson’s fully-sealed filtration system, means our whole purifier meets HEPA H13 standard. So what goes inside, stays inside.
Some manufacturers publish dB readings based on Sound Pressure levels, which can be easily manipulated by changes in the environment. They might also be tested at low fan speeds which can limit purification performance.
At Dyson we measure and publish Sound Power levels dB(A) – the pure reading taken directly from the machine – at maximum fan speed, where purification is at its optimum.
Increased CO₂ levels can impact cognitive function. Our latest purifier senses and reports CO₂ levels and notifies when they exceed recommended levels, alerting on the LCD screen when to ventilate.
-
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.
