Many indoor activities and household products emit pollution
Cooking, cleaning, even getting ready for work can release inhalable pollutants into your home. Dyson air purifiers automatically diagnose your air quality – sensing and capturing airborne particles, and displaying real-time reports on the LCD screen or your MyDyson™ App.
Three key things to look for in an air purifier
Automatic sensing, a fully-sealed 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.
Reacts automatically to remove pollutants, only using energy when needed.¹
Fully sealed to HEPA H13 standard. So the pollution captured inside stays inside.²
Long-range air projection
Dyson Air Multiplier™ technology projects purified air into every corner of the room.³
Tested for real homes
Standard Clean Air Delivery Rate (CADR) tests in small chambers with ceiling fans don't represent real living conditions.
So our engineers spent years developing a new testing methodology, called Point Loading Auto Response (POLAR), to measure real-world performance more accurately.

Frequently asked questions
Indoor air pollution contains a mix of pollutants, including particulate matter (PM) and volatile organic compounds (VOCs).
Many indoor activities and household products release invisible pollutants. As our homes become increasingly well-sealed, it may seem like we're shutting pollution out – but in truth, we may be shutting it in.
Four indoor air pollutants which may be causing poor air quality in your home are:
Mould. Moulds are fungi that reproduce by making and releasing spores. It's usually found where there is excess moisture.
Volatile organic compounds. Or VOCs, can be released from building materials, personal care and cleaning products.
Particulate matter. These can include dust, smoke and exhaust fumes. Particles vary from PM0.3 - PM10 in size.
Allergens. Common allergens include pollen and pet dander. Biological pollutants from pets include multiple proteins in a pet’s fur, hair, saliva, urine or dander.
Dyson's sealed HEPA filters capture 99.97% of microscopic allergens and pollutants as small as 0.3 microns.
Here are a few actions you can take to improve the air quality in your home:
Invest in an air purifier. Your best solution for improving your indoor air quality is an air purifier. Be sure to choose one which automatically senses, is fully sealed, and has long-range air projection.
Get rid of dust. House dust can be a combination of dust mites, pet dander and pollen. Keeping on top of cleaning and vacuuming can help overall air quality.
Source control. Reduce pollution sources in your home (like burning scented candles).
Unlike our competitors, every Dyson air purifier is fully sealed to HEPA H13 standard. This ensures we capture 99.95% of ultrafine particles⁴ and prevents pollutants from leaking back into the air you breathe.
VOCs are 'Volatile Organic Compounds', meaning they are compounds containing carbon and are generally a gas at room temperature. Indoor VOCs can come from a range of activities, such as spraying perfumes or hair sprays, painting or cleaning.
When you see VOC on your machine's monitor or in your MyDyson app, you're experiencing a rise in VOCs, and your machine is working hard to remove the pollutant from the air, and project cleaned air into your home.
PM2.5 is particulate matter with a size of 2.5 microns or less, for example dust, ash and smoke particles. These can be released from a range of household activities such as burning candles or cooking.
When you see PM2.5 on your machine's monitor or in your MyDyson app, you're experiencing a rise in PM2.5, and your machine is working hard to remove the pollutant from the air, and project cleaned air into your home.
