Dyson PH3A Purifier Humidify & Cool Auto React

Automatically purifies and hygienically humidifies for a healthier, more comfortable environment

The latest Dyson purifier humidifier is engineered to help improve your air quality. An advanced filtration system combines an activated carbon filter to remove gases and odors with a HEPA filter to capture 99.97% of particles 0.3 microns in size. Powerful Air Multiplier™ technology projects purified, humidified air throughout the room.³

Circulates purified humidified air

Dyson Air Multiplier™ technology mixes and circulates purified, humidified air throughout the room.

Cools you when needed

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 and react to pollution events.

Continuous 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. 

Backward airflow mode

Diverts airflow through the back of the machine to purify and humidify without cooling you.

Breeze 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.

Note: Dyson machines are not capable of lowering the temperature of a room. The cooling effect from the fan occurs as the speed of the air flow from the machine comes into contact with your skin. This is the same as any conventional fan. Where the Dyson differs is by providing a smooth and constant airflow, whereas bladed fans will buffer producing interrupted airflow.
