Cooking odours and NO₂
Cooking doesn’t just leave lingering odors. It can also release potentially harmful pollutants like NO₂ when any fuel is burned, which can build up in your home.

Pet odours and dander
Pets can bring unwanted odors and allergens* into the home. Dogs and cats shed dander, releasing microscopic skin and saliva into the air.

Allergens* such as pollen
Pollen season can make life difficult. Dyson purifiers reduce your exposure to allergens* like these, so you and your family can breathe cleaner air.

VOCs from cleaning products and aerosols
Some household products like disinfectants and aerosols can release potentially harmful gases into the air. These are known as volatile organic compounds (VOCs).

Frequently asked questions
Dyson Purifier Cool PC2 De-NOx has all of the capabilities found in our Dyson Purifier Cool Formaldehyde products but goes a step further to now capture more NO₂.± The new K-Carbon filter is impregnated with potassium carbonate (K₂CO₃) and can adsorb 50% more nitrogen dioxide± – a common and potentially harmful household pollutant, produced by gas appliances, open flames, and wood burning stoves.
The formaldehyde-destroying catalytic filter never needs replacing. And we recommend replacing the HEPA+K-Carbon filter every 12 months19 (based on 12 hours a day of use) – so this may vary depending on usage and pollution levels. You'll be notified via the MyDyson™ app or LCD screen when it’s time to replace the filter.
Dyson Purifier Cool PC2 De-NOx can serve as a fan, which can help cool you. It projects over 76 gallons per second of smooth, yet powerful cooling airflow.7 It is not an air conditioner.
