Powerful air purification for every room in your house

This Dyson purifier big+quiet formaldehyde tackles the air quality challenges of large homes, covering spaces up to 100 square metres while running quieter than most desk fans. It captures 99.95% of ultrafine particles and permanently destroys formaldehyde gas that can leak from furniture and flooring for years.

You get cleaner air faster across your entire living space, whether that's an open-plan kitchen and lounge or multiple connected rooms. The three-phase filtration system traps allergens, dust, pet dander and odours while the sealed design ensures captured pollutants stay locked inside. Smart sensors detect air quality changes and adjust power automatically, so it only works as hard as needed to keep your air clean.

The sleek bright nickel and Prussian blue design fits naturally into modern homes, while the MyDyson app lets you monitor air quality, set schedules and control the unit remotely. At just 56 decibels on full power, it runs quietly enough for bedrooms and living areas without disrupting sleep or conversation. The directional airflow can be angled to suit your room layout.
