The Dyson Purifier Humidify+Cool Formaldehyde PH04 combines air purification, humidification and cooling in a single tower, automatically responding to changes in air quality. It’s built for larger living rooms and bedrooms where several jobs — cleaning, humidifying and circulating the air — need to be handled by one machine.
Key features
- HEPA H13 and activated carbon filtration — captures 99.97% of particles as small as 0.3 microns, including allergens and odours.
- Formaldehyde sensor and catalytic filter — continuously monitors and breaks down formaldehyde without needing a filter change for this function.
- Hygienic humidification — UV-treated water is turned into a fine mist, keeping the tank free of bacteria between refills.
- Three airflow modes — direct Fan mode, wide-angle Breeze mode, and rear-facing airflow for purifying and humidifying without a cooling draught.
- Night mode — dims the display and runs on quieter settings while still monitoring air quality.
- Real-time reporting — the LCD screen and Dyson app show live air quality readings and filter life.

Good to know
Fill the tank with tap water and descale periodically to keep the humidification system working efficiently. Filter and formaldehyde sensor status are shown on the display and in the Dyson app, so replacements can be timed to when they’re actually needed.
