From the manufacturer
Poor air quality isn't just a problem outside
It’s a problem inside too. Household items release pollutants that can get trapped in our homes. That's why Dyson purifiers automatically sense and remove them.
Fully sealed to HEPA H13 standard
To prevent pollutants from leaking back into the air, the whole purifier is sealed to HEPA 13 standard, not just the filter. So what goes inside, stays inside.
Backwards airflow mode
Diverts airflow through the back of the machine to purify the room without cooling you.
Night mode
Monitor and purifies using the quietest settings with a dimmed display.
Easy filter care
Changing the HEPA+ Carbon filter is quick and easy, with automatic notifications on the LCD screen and MyDyson app.² The catalytic filter never needs replacing.
Intelligent control
Control and monitor your air quality from anywhere using the MyDyson app.
