Frequently asked questions

What makes the Dyson Purifier Big+Quiet Formaldehyde different from other air purifiers?

The BP03 is Dyson’s quietest and most powerful air purifier, engineered for large spaces up to 100m². It uses advanced cone aerodynamics for long-range air projection and features a three-stage filtration system (HEPA H13-grade, Activated Carbon, and Selective Catalytic Oxidisation) to remove gases, odours, dust, allergens, viruses, bacteria, and even formaldehyde. It also cools you in hot weather and is designed for quiet operation. 

How effective is the BP03 at removing pollutants and allergens?

The BP03 captures 99.95% of ultrafine particles as small as 0.1 microns, such as dust, pollen, pet dander, mould spores, and smoke. It also removes gases like benzene and nitrogen dioxide and continuously destroys formaldehyde. The purifier is proven to capture 99.9% of viruses. 

Does the BP03 help with odours and VOCs?

Yes, the advanced filtration system includes an Activated Carbon filter that removes odours and volatile organic compounds (VOCs) from sources like cooking, cleaning products, and pets. 

How quiet is the BP03 in operation?

The BP03 is acoustically engineered to be 50% quieter than any other Dyson purifier, even at full power. Night mode further reduces noise for undisturbed sleep.  

How do I clean or replace the filters, and how long do they last?
  • HEPA H13-grade filter: Lasts up to 11 years (based on 12 hours use per day; actual life may vary).

  • Activated Carbon filter: Lasts up to two years.

  • Selective Catalytic Oxidisation (SCO) filter: Permanent and never needs replacing. Filters are easy to remove and replace with a one-click mechanism. 

Where should I place the BP03 for best results?

For optimal performance, place the BP03 in a corner of the room, at least one metre away from the wall. Project air along a wall or across the room and adjust the angle of projection as needed. The discreet wheels make it easy to move the purifier around hard floors. 

Can I control the BP03 remotely or via an app?

Yes, the BP03 comes with a remote control and can be managed via the MyDyson™ app. The app lets you monitor air quality, set schedules, and view reports from anywhere. 

Does the BP03 provide heating or cooling?

The BP03 cools you in hot weather by projecting purified air, but it does not have a heating function.

What maintenance does the BP03 require?

Regularly check the filter status via the app or display. Replace filters as recommended. The machine is designed for easy maintenance, with filters that are simple to access and replace. 

How energy efficient is the BP03?

In Auto mode, the BP03 uses energy only when needed. It reacts automatically to air quality changes and is designed for efficient purification of large spaces.

What support is available for BP03 owners?
You can register your machine, explore accessories, find the right part, and access expert support online. The Dyson Community and Digital Assistant are also available for troubleshooting and advice.
