Common pollutants found in the home
Invisible pollutants are sourced from a range of household products and indoor activities – even pets reduce air quality in the home. The benefits of air purifiers help to create cleaner air and reduce triggers of allergy symptoms.
-
Cleaning the house
When disinfectants and aerosols are sprayed indoors, the particles form vapours that are then breathed in.
Volatile organic compounds (VOCs) are potentially harmful gases released by household products like multi-purpose sprays and air freshener. When scented cleaning products are used on a regular basis, VOC concentrations in the home increase. Short-term exposure to high concentrations can result in wheezing and irritation to the eyes, nose and throat, and in some cases trigger asthma. The use of air purifiers can help with allergens and improve air quality. -
Quality time with your pet
Air purifiers remove odours and allergens released from the proteins found in pet’s hair, saliva and urine, which may trigger allergic reactions.
Pet dander is made up of tiny, microscopic flakes of skin and protein particles. As pets move around the home, their dander lingers in the air before settling on surfaces. Exposure to these airborne particles can cause unpleasant symptoms such as sneezing or itchy eyes. -
A good night's sleep
People share their bedrooms with a collection of biological particles and allergens that are often inhaled during sleep.
Airborne dust, bacteria and pollen can build up in the bedroom where ventilation is typically worse than other rooms. When doors and windows are closed at bedtime, exposure to trapped pollutants is prolonged. Poor ventilation in the bedroom for an extended period can result in worsened sleep. The clean air benefits of air purifiers help to improve and maintain sleep. -
Cooking for loved ones
Frying food with oil at high temperatures can release oil particles and odours into the air.
The emissions released from cooking can vary based on the cooking temperature, method and ingredients. More emissions are generated when fatty ingredients like oil and salmon are cooked at high temperatures. Even after cooking, potentially harmful pollutants can hang around in the air. Air purifiers can remove cooking odours and oil particles from the air. -
Working out at home
During periods of physical activity, more airborne pollutants are inhaled as a result of faster breathing.
Dust mites, pollen, skin cells, and pet dander are typical allergens found in house dust composition. Movement throughout the home can disturb settled dust, making it airborne. Air purifiers can reduce the amount of dust in the air which contributes to asthma and eczema, inflammation of the nose, nasal congestion and sneezing. -
Decorating the nursery
The smell of new paint might fade over time, but the emission of VOCs like formaldehyde can persist for years.
Formaldehyde is a colourless gas released by some furniture and DIY materials such as paint, wallpaper and fabrics. Almost every home contains small amounts of formaldehyde, but concentrations increase during interior decoration projects. Prolonged exposure to the emission of formaldehyde can cause irritation of the eyes, throat and lungs. Learn more about the Dyson Hot+Cool™ Formaldehyde air purifying fan heater.
Three key things to look for in an air purifier
Automatic sensing, a filtration sealed to the industry standard machine and long-range air projection are key to effective air purification. That's why they're at the core of our technology. And why we've been testing them for generations.

-
Senses and reports automatically
Most indoor pollutants can't be seen or smelled. Dyson air purfiers constantly monitor your indoor air quality – automatically sensing airborne particles and then displaying real-time reports on the LCD screen for proof of cleaner air.
-
Whole-machine sealed
In our latest air purifiers it's not just the filter that's sealed to HEPA 13 standard, it's the whole machine.2 This prevents pollutants from being expelled back into the room after they've been removed from the airflow. So what goes inside, stays inside.
-
Purifies the whole room
We test our machines beyond industry standards, so they're suitable for real homes. Only Dyson air purifiers are engineered with Air Multiplier™ technology, to draw in distant pollutants and project purified air into every corner of the room.3

Frequently asked questions
Dust and allergens impact indoor air quality, but their differing size range requires unique filters. Dyson’s air purifiers use different filter layers to draw in and capture particles as small as 0.1 microns2, odours, allergens and gases.
Allergies can be caused by a range of triggers. Pet dander, mould, pollen and dust mites can travel indoors and cause allergies and asthma symptoms like a runny nose and itchy throat. Dyson’s air purifiers capture allergens in air that trigger these symptoms.
Pet hair is removed from the home via effective vacuuming and cleaning schedules. Odours and gases including VOCs can be captured by filters which contain activated carbon. Dyson’s purifiers use activated carbon alongside other filter layers.
Indoor air quality can be impacted at any time of year by a range of pollutants. Air purifiers can improve air quality and support home health, by trapping and removing pollutants.
To ensure the air you breathe while you sleep is purified, an air purifier can be placed in your bedroom. This can help to capture dust, particulate matter and gases. Dyson’s purifiers with temperature control also help to maintain comfortable heat levels as you sleep.
Odours can emit from a range of sources – such as pet urine, cleaning products and cooking odours. Dyson’s latest purifiers can help to remove odours.2
Dyson’s air purifiers can function as you need. Diffused mode diverts airflow through the back of the machine to purify the whole room, without cooling you. This means you can use your Dyson purifier all year round.
