Dyson PH04 Purifier Humidify+Cool Formaldehyde - White/Gold

Senses and reports, automatically
Three sensors constantly monitor your air – diagnosing pollutants at a molecular level and displaying live air quality in real-time reports.

Captures gases and ultrafine particles
Captures 99.95% of particles as small as 0.1 microns.³ Combined with activated carbon, it also removes odours and gases including VOCs.⁵

Destroys formaldehyde, continuously.
A catalytic filter continuously traps and breaks down formaldehyde molecules into water and CO₂¹. And it never needs replacing.

Precisely detects formaldehyde
A lifetime solid-state sensor detectsformaldehyde molecules – 500 times smaller than 0.1 microns.
 
Destroys potentially harmful bacteria
Dyson Ultraviolet Cleanse technology exposes every drop of water to a powerful λ275nm UV light, to hygienically humidify.
 
Fully sealed to HEPA standard
To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA standard, it's the whole purifier humidifer.
