Dyson | Air purifier Purifier Cool AutoReact

We spend 90% of our time indoors. House dust, allergens and pollens can accumulate inside your home. All these pollutants can accumulate invisibly, contaminating the air you breathe.

The Dyson Purifier Cool Autoreact gives you a cleaner, more hygienic home by capturing 99.95% of pollutants as fine as 0.1 microns¹, such as dust, allergens and viruses.

Detects and reports
The latest Dyson Purifier Cool features a new detection system consisting of 3 sensors:

1) particles 
2) humidity and temperature 
3) gases.
It constantly analyzes your air and the pollutants lurking in it. A unique algorithm checks the data several times a second, detects pollutants at a molecular level and displays the results in real time on the LCD screen.

Capture and destroy
The device features an advanced filtration system consisting of a fully hermetically sealed H13 360° HEPA filter that captures 99.95% of ultra-fine particles, such as dust, allergens and viruses¹. Combined with a layer of activated carbon, it is also capable of eliminating potentially harmful odors, gases and VOCs¹. For our latest purifiers, it's not just the filter that complies with HEPA H13 standards designed to prevent pollutants from re-entering the air - the entire unit does too². So what goes in stays in.

Disperses the air
What's more, only Dyson purifiers feature Air Multipler™ technology, which captures dirty air and disperses clean air throughout the room³. The Dyson Purifier Cool generates a unique projection circuit that multiplies the airflow up to ten times. The circulating power draws even the most distant pollutants into the unit, purifying the whole room with an airflow of up to 290 l/s3.

Several built-in, configurable functions let you control the power and direction of the airflow. Thanks to the adjustable oscillation, you can decide where you want to throw the air by rotating the unit up to 350°. In warmer temperatures, a powerful stream of purified air can refresh you, while the ambient mode distributes a stream of air from the rear of the unit to purify without cooling you. The acoustics of the new Dyson purifier have also been improved to be 20% quieter than the previous model, and 50% quieter in night mode, when the unit controls and purifies using the quietest settings, with lower brightness.
