Features
Circulates purified humidified air
Dyson Air Multiplier™ technology mixes and circulates purified, humidified air throughout the room.
Cools you
In warmer weather, a powerful stream of purified, humidified airflow can cool you down.
Real data, real time
Control and monitor your air quality from anywhere using the MyDyson™ app.⁵
Auto mode
Constantly monitors your air quality, automatically adjusting airflow to reach and maintain the most comfortable humidity level.
Diffused mode
Diverts airflow through the back of the machine. To purify and humidify, without cooling you.
Voice control
Control it hands-free with compatible voice services, including Amazon Alexa, Siri and Google Assistant.⁹
Continuous humidification
An efficient water management system and a one gallon tank give you up to 36 hours* of hygienic humidification without regular refilling.
Breeze mode
Unique algorithms vary the airflow to mimic a cooling, refreshing breeze.
Deep clean cycle
Activate the machine's monthly hassle-free Deep clean cycle at the touch of a button. It will guide you through the simple step-by-step process.
Night mode
Purifies using the quietest settings and a dimmed display. Sleep timer enables pre-set intervals of use, between 15 minutes and 9 hours.
Jet Axis control
Two oscillators guide the airflow – projecting separately, or in unison, so you can choose different airflow modes.
Simple filter changes
Built-in reminders show you when your combination filter needs changing. It's quick and easy to do.
Technology
-
Senses and reports, automatically
Three sensors constantly monitor your air – diagnosing pollutants at a molecular level and displaying live air quality in real-time reports.
-
Captures gases and ultrafine particles
Captures 99.95% of particles as small as 0.1 microns.³ Combined with activated carbon, it also removes odours and gases including VOCs.⁶
-
Destroys formaldehyde, continuously.¹
A catalytic filter continuously traps and breaks down formaldehyde molecules into water and CO₂. And it never needs replacing.
Precisely detects formaldehyde
A lifetime solid-state sensor detectsformaldehyde molecules – 500 times smaller than 0.1 microns.
Destroys potentially harmful bacteria
Dyson Ultraviolet Cleanse technology exposes every drop of water to a powerful λ275nm UV light, to hygienically humidify.
Fully sealed to HEPA H13 standard⁵
To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier humidifer.⁵

Frequently asked questions
We've re-engineered our latest purifier humidifier to be fully sealed to HEPA H13 standard.⁶ With a hassle-free Deep clean cycle that eliminates mineral build-up throughout your machine's water system.
The Dyson Purifier Humidify+Cool™ Formaldehyde has all of the capabilities found in our advanced purification products but goes a step further to detect and destroy formaldehyde.¹ An added solid-state sensor precisely detects formaldehyde, while our catalytic filter breaks it down into two safer molecules – carbon dioxide and water.
Formaldehyde is a polluting gas formed of carbon, hydrogen and oxygen that is commonly found in homes. Common sources of formaldehyde could be: paint and varnishes, air fresheners, mattresses, furniture, household cleaners, carpets, particleboard and plywood, electronics, dryer sheets, nail polish remover, moth balls, toys, fireplaces and wood burning stoves.
Your Dyson Pure Humidify+Cool™ Formaldehyde is engineered to purify and humidify single rooms, so you should use it where you spend the majority of your time at home. When placing the machine, make sure there's at least a few feet of clearance on all sides, so that the air can circulate effectively. Close doors and windows and place away from air vents.
Yes. The machine works as a purifier humidifier, or just a purifying fan.
This depends on the water hardness where you live. The machine prompts you to run the cycle once a month in hard water areas. It prompts you less often in softer water areas. You can select your water hardness with the MyDyson™ app. Running a Deep clean cycle helps to eliminate odours that occur through poor maintenance.
Glossary
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
Helpful tips about humidifying your air
Dyson purifier humidifiers let you achieve your desired humidity either automatically or manually. In Auto mode, just set it and forget it. In manual mode, the LCD indicates if you need to increase airflow – which may help you reach your target quicker. And remember, keeping your machine away from drafts and turning down your home’s heating or AC units can also improve performance.
