Dyson Purifier Hot+Cool™ HP7A Autoreact (White/Nickel)
Features
Heats in winter
With long-range projection, it’s quick to heat the whole room evenly.⁵
Cools you in summer
In warmer weather, a powerful stream of purified airflow can cool you down.
Draught-free diffused mode
Diverts airflow through the back of the machine. To purify, without cooling you.
Oscillates up to 350 ̊
Adjustable oscillation projects purified air around the whole room.
Remote
Curved and magnetised to store neatly on top of the machine.
Night mode
For lighter sleepers. Monitors and purifies using the quietest settings, along with a dimmed display.
Easy filter care
The filter is quick and easy to change. With automatic filter-life notifications on the LCD screen.
Technology
Senses and reports automatically
Integrated sensors constantly analyse your air, while our unique algorithm cross-checks data every second. It diagnoses pollutants at a molecular level, displaying live results on the LCD.
Captures gases and ultrafine particles
The HEPA H13 filter captures 99.95% of particles as small as 0.1 microns.³ A layer of activated carbon also removes odours and gases including VOCs².
Fully sealed to HEPA H13
In our latest purifiers, it's not just the filter that meets HEPA H13 standard, it's the whole machine⁴. So what goes inside, stays inside.
-
Purifies the whole room
Only Dyson purifiers have Air Multiplier™ technology. It generates the circulation power to draw even distant pollutants into the machine, projecting purified air throughout the room.⁵
-
Heating your whole home can be unnecessary
Dyson heater purifiers provide long range and whole room even heating solutions in winter, so you don't have to heat your whole home. Dyson heater purifiers have an intelligent thermostat, so it stops heating once the correct temperature is reached and energy is not wasted.

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.
-
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.
-
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.
-
Dust mites
House 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.
-
Formaldehyde (HCHO)
Formaldehyde is often associated with the familiar smell of fresh paint, or the unboxing of new furniture. It's a colourless, flammable and potentially harmful gas used in some building materials and household products. Sources can include 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
HEPA (High Efficiency Particulate Air) is an air filter efficiency standard and a measure of a filter’s performance. For an air filter to be classified as HEPA, it must be capable of removing at least 99.95% (ISO, European Standard) or 99.97% (ASME, U.S. DOE) of particles whose diameter is equal to 0.3 microns.
-
HEPA 13
HEPA H13 is an even higher tier of HEPA air filtration efficiency. To meet HEPA H13 standards, a filter must be able to remove 99.95% (ISO, European Standard) or 99.97% (ASME, U.S. DOE) of microscopic particles at the most penetrating particle size of 0.1 microns.
-
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.
-
Micron
Airborne particles are usually described in microns. One micron is equal to one-thousandth of a mm. The human eye struggles to see anything smaller than 25 microns in size. Allergens are microscopic. The size of dust mite allergens, mould spores and other insect allergens is often between 0.5 to 5 microns. To provide context, the diameter of a human hair is around 50 microns.
-
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)
PM stands for particulate matter, which consists of microscopic solid or liquid particles and pollutants. PM is often followed by a number, which represents the size of the particulate matter in microns (a micron is one-thousandth of a mm). For example, PM01 means particulate matter that is 0.1 of a micron in size. PM2.5 equals particles that are 2.5 microns in size, and PM10 means particles up to 10 microns in size. Indoor PM can be generated through many day-to-day activities, including 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.
-
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.
-
Selective Catalytic Oxidisation (SCO)
SCO is an abbreviation for Dyson's Selective Catalytic Oxidisation filter, a specific type of filter engineered to capture and destroy formaldehyde at the molecular level. Dyson SCO filters break the pollutant down into tiny amounts of water and CO₂. Our filter then naturally regenerates from the oxygen in the air, so it can keep destroying formaldehyde continuously, without ever needing to be replaced.
-
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.
