Dyson | Air purifier Big+Quiet Formaldehype

Bring a breath of purity into your home with the Dyson Big+Quiet Formaldehyde, a large-format air purifier designed to clean large spaces with exceptional power… in complete silence.

HEPA H13 filtration + permanent formaldehyde destruction
This purifier doesn't just capture 99.97% of ultrafine particles thanks to its HEPA H13 filter. It goes even further, detecting and permanently eliminating formaldehyde – an often invisible pollutant emitted by furniture, flooring, or paint – using an exclusive catalytic filter. The result: healthier, purer air, day after day.

Connected technology for total control
With the MyDyson app, you can monitor and control your air quality from anywhere. Thanks to a Wi-Fi or Bluetooth connection, you get real-time access to your device's data, schedule cycles, track performance and customize your comfort with just a tap on your smartphone.

A natural breeze, remarkably quiet
The exclusive "Breeze" mode recreates the feeling of a light, natural wind indoors – a real breath of fresh air. And for nighttime, choose "Night mode": quiet purification, dimmed display, and peaceful sleep.

Power and discretion, even in large spaces
Designed for large rooms, the Dyson Big+Quiet propels purified air up to 10 meters while remaining incredibly quiet. Its cone-shaped aerodynamic design distributes a constant, gentle airflow without unpleasant drafts.

Personalized comfort
Enjoy total flexibility with the programmable shutdown: choose a duration from 30 minutes to 8 hours to adapt the device’s operation to your daily routine.

The Dyson Big+Quiet Formaldehyde brings together the best of Dyson technology: efficiency, connectivity, comfort and silence. A premium solution to transform your indoor environment for good.
