Humidification and cooling with advanced air purification
Hygienically humidifies the air11 and cools you.3 Removes dust, odours, allergens and bacteria – for a healthier home environment.
Air pollution isn’t just outside – it’s inside too
Cooking odours and NO2
Cooking doesn’t just leave lingering odours. 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 odours and allergens into the home. Dogs and cats shed dander, releasing microscopic skin, saliva and urine allergens 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).

Discover the pioneering technology inside the machine
Senses
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 screen and in the MyDyson™ app.8
Filters
The fully-sealed, three-stage filtration system traps pollutants inside the machine. It captures 99.95% of ultra-fine particles5, removes odours and gases6, and continuously destroys formaldehyde.7
Projects
Air Multiplier™ technology delivers over 320 litres per second of smooth, yet powerful airflow.3
Hydrates
Dyson Ultraviolet Cleanse technology exposes every drop of water to a powerful λ275nm UV light, killing 99.9% of bacteria in the water.4 Hydrating the air hygienically.11
Adsorbs 50% more NO21
Our K-Carbon filter is impregnated with potassium carbonate (K2CO3) and can adsorb 50% more nitrogen dioxide – a common and potentially harmful household pollutant.1
Frequently asked questions
Dyson Purifier Humidify+Cool PH2 De-NOx has all of the capabilities found in our Dyson Purifier Humidify+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 dioxide1 – 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 months10 (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™ app8 or LCD screen when it's time to replace the filter.
Dry air can cause your skin to lose moisture. Dyson purifier humidifiers are scientifically proven to help your skin feel hydrated and maintain moisture balance.14
