Dyson PH3A Purifier Humidify Cool Autoreact Dyson PH3A Purifier Humidify Cool Autoreact
Captures 99.95% of ultrafine particles³
Purifies and hygienically humidifies a whole room²
Fully-sealed to HEPA H13 standard⁵
A cleaner, more comfortable environment
The Dyson purifier humidifier is engineered to help improve your air quality. Its activated carbon filter removes gases and its HEPA H13 filter captures 99.95% of particles as small as 0.1 microns.³ Air Multiplier™ technology then projects purified, humidified air throughout the room² – cooling you when required.

Technology
Senses and reports automatically
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.
Captures gases and ultrafine particles
The HEPA H13 filter captures 99.95% of particles as small as 0.1 microns.¹ A layer of activated carbon also removes odours and gases including VOCs.²
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 H13
To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier humidifer.⁵
Features
Circulates purified humidified air
Dyson Air Multiplier™ technology mixes and circulates purified, humidified air throughout the room.
Cools you
In warmer weather, a powerful stream of purified, humidified airflow can cool you down.
Auto mode
Constantly monitors your air quality, automatically adjusting airflow to reach and maintain the most comfortable humidity level.
OContinuous humidification
An efficient water management system and a one gallon tank give you up to 36 hours* of hygienic humidification without regular refilling.
Night mode
Purifies using the quietest settings and a dimmed display. Sleep timer enables pre-set intervals of use, between 15 minutes and 9 hours.
Diffused mode
Diverts airflow through the back of the machine. To purify and humidify, without cooling you.
OBreeze mode
Unique algorithms vary the airflow to mimic a cooling, refreshing breeze.
Jet Axis control
Two oscillators guide the airflow – projecting separately, or in unison, so you can choose different airflow modes.
Deep clean cycle
Activate the machine's monthly hassle-free Deep clean cycle at the touch of a button. It will guide you through the simple step-by-step process.
Simple filter changes
Built-in reminders show you when your combination filter needs changing. It's quick and easy to do.
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.⁶
