Frequently asked questions
What is different about the Dyson Purifier Humifidy+Cool PH2 De-NOx range?
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 dioxide± – a common and potentially harmful household pollutant, produced by gas appliances, open flames, and wood burning stoves.
What’s the lifespan of the filter in a Dyson purifier?
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™ app5 or LCD screen when it's time to replace the filter.
How do Dyson purifier humidifiers benefit your skin?
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.18
