Big and Quiet

In today’s homes, air quality is as crucial as aesthetics, and Dyson’s latest innovation brings both together in one beautifully engineered device. The Dyson Purifier Big+Quiet Formaldehyde BP03 is a sleek, sculptural piece of smart tech that delivers ultra-efficient purification for large interiors, all while operating at an impressively low hum.

From open-plan living areas and creative studios to hospitality spaces and wellness retreats, this advanced purifier is engineered to perform – quietly. At just 56 decibels, it’s Dyson’s quietest yet most powerful purifier to date, combining groundbreaking technology with a clean, minimalist silhouette that sits comfortably within any interior.

The air purifier is capable of projecting purified air up to 10 metres (over 32 feet) using cone aerodynamics. By harnessing the ‘Coanda effect’, it merges twin air streams over the machine’s dome into one high-velocity jet, quietly delivering more than 87 litres of purified air per second. The purifier is also equipped with a Helmholtz silencer and a labyrinth seal, which acoustically insulate the re-engineered motor, enabling whisper-quiet operation even when performing at its most powerful.

Dyson’s three-phase, fully sealed filtration system targets pollutants that often go unnoticed. It captures 99.97% of particles as small as 0.3 microns (think allergens, mould spores, dust and bacteria) while also tackling gases and odours from everyday activities like cleaning, cooking and decorating.

But, perhaps most impressively, it features a solid-state formaldehyde sensor that is able to detect and destroy this persistent pollutant continuously and permanently. The K-Carbon filter, infused with potassium carbonate, absorbs up to three times more nitrogen dioxide (NO₂) than previous models, helping combat emissions that can sneak into our homes from busy streets and nearby traffic.

A network of integrated sensors inside the purifier continuously monitors the indoor environment, detecting CO₂, fine particulates and more. In auto mode, the device cross-checks air quality data every second and adjusts its performance accordingly. Insights are available at a glance on the onboard LCD display, or via the MyDyson app, offering full control and reporting in real-time.

For design professionals and discerning homeowners, this seamless combination of performance, quiet operation and unobtrusive beauty makes this air purifier an ideal addition to clean-lined, tech-forward spaces.
