Quiet power for clean air
The Dyson Purifier Big+Quiet Formaldehyde BP04 is a premium air purifier designed for large spaces, combining maximum efficiency, intelligent technology and an unobtrusive design. Thanks to its aerodynamic cone, it can effectively circulate air over long distances, capturing even distant pollutants and purifying the air evenly throughout the room. Even at full power, it reaches just 56 dBA. You can customise the airflow angle or use the Breeze mode for gentle refreshment. With its automatic mode, the purifier detects and captures pollutants in real time. The purifier also intelligently monitors CO₂ levels, recommends ventilating the room, and uses advanced sensors and algorithms to continuously evaluate air quality. Replacing the HEPA filter is hygienic and quick thanks to a one-click mechanism, and moving the Dyson Purifier Big+Quiet Formaldehyde BP04 is made easy by concealed castors for hard floors.


The Dyson Purifier Big+Quiet Formaldehyde BP04 takes air purification to a new level. Thanks to its innovative aerodynamic cone, it can project a strong, precise airflow over long distances. It effectively circulates the air throughout the room, capturing even the most distant pollutants and returning them through the hermetically sealed filters. The result? Evenly clean air, not just in smaller rooms, but also in large open spaces.

The Dyson Purifier Big+Quiet Formaldehyde BP04 combines maximum performance with exceptionally quiet operation. Thanks to its acoustically optimised motor housing, it reaches only 56 dBA at full power, so it won't disturb your work, rest or sleep. You can enjoy clean air to the full and in peace.

With the Dyson Purifier Big+Quiet Formaldehyde BP04, you're in control of every gust. You can easily set the airflow angle to 0°, 25° or 50° to direct fresh air exactly where you need it. And when you're longing for gentle refreshment, just turn on Breeze mode, which mimics a natural, light breeze and brings a fresh-air feeling right into your interior.

With the Dyson Purifier Big+Quiet Formaldehyde BP04, you can keep an eye on your air quality wherever you are. Through the MyDyson™ app, you can see what particles have been captured, set purification schedules, browse detailed reports and much more. Thanks to its compatibility with smart home voice assistants, you can also control the purifier conveniently with your voice.

In automatic mode, the Dyson Purifier Big+Quiet Formaldehyde BP04 can continuously monitor the air quality in your home. It detects pollutants in real time, captures them and gives you precise information about them. Thanks to smart optimisation, it only consumes energy when it's really needed – keeping the air clean and your home energy-efficient at the same time.

Thanks to a smart replacement mechanism, maintaining the Dyson Purifier Big+Quiet Formaldehyde BP04 is fast, clean and without unnecessary contact with dirt. You simply release the HEPA filter with a single click and dispose of it safely.

The Dyson Purifier Big+Quiet Formaldehyde BP04 is easy to move around the room thanks to its discreetly integrated castors, without disturbing its appearance. The specially designed castors for hard surfaces ensure smooth and quiet movement, so you can place the purifier exactly where you need it.

The Dyson Purifier Big+Quiet Formaldehyde BP04 can handle even the most dangerous pollutants. Its catalytic filter continuously breaks down formaldehyde molecules into water and CO₂ – and it does so permanently, without the need for replacement. The HEPA H13 filter captures 99.95% of ultrafine particles as small as 0.1 microns, while the activated carbon filter effectively removes odours and gases. Thanks to the fully sealed construction to HEPA H13 standard, you can be sure that the three-phase purification system keeps everything it captures inside. The result? The air you breathe is clean, safe and fresh.

The special K-Carbon filter in the Dyson Purifier Big+Quiet Formaldehyde BP04 is impregnated with potassium carbonate (K₂CO₃), allowing it to adsorb up to three times more nitrogen dioxide. This is often found indoors, where it is produced by gas appliances, open fireplaces or wood-burning stoves. With this technology, you get an extra layer of protection for a cleaner, healthier home.

Elevated CO₂ levels can negatively affect your concentration and overall cognitive function. The Dyson Purifier Big+Quiet Formaldehyde BP04 therefore intelligently monitors CO₂ levels and alerts you immediately if they exceed recommended values. It also advises you when to open windows or doors and ventilate the room via the MyDyson™ app or the LCD. A set of advanced sensors, including a solid-state formaldehyde sensor, detects pollutants throughout the room. A unique algorithm cross-checks data every second and analyses the air at a molecular level. The result is an automatic response from the purifier, instant display of the results on the LCD screen and in the app, and above all, perfectly clean air for you to breathe.
