It's our business to understand air pollution, so yours doesn't suffer
Workspaces can harbor pollutants such as Volatile Organic Compounds (VOCs), pollen and formaldehyde. Everyday items such as cleaning products and printers, furniture and flooring, can release potentially harmful gases, and remain in the air for many years.
Dyson purifiers remove these common pollutants from commercial environments
-
Formaldehyde
Paint, varnishes and printers
-
Benzene and VOCs
Traffic, building materials and furniture
-
Odors
Fumes and cooking
-
PM10
Pollen, dust and allergens
-
PM0.1
Ultrafine particles
-
Engineered to purify
large spaces
Fully-sealed to HEPA H13 standard² to capture 99.97% of pollutants as small as 0.3 microns. Purifying rooms up to 1,000ft², evenly.¹
Senses, captures and destroys
-
Senses and reports CO₂ levels
1.44 inch LCD screen displays carbon dioxide readings and airflow mode – senses and reports air quality levels in real time.
-
Whole-machine HEPA 13 filtration²
Three phases of purification draw pollutants in from all directions. And the whole machine is fully sealed to HEPA H13 standard² – so what goes in, stays in.
-
Destroys formaldehyde, continuously³
The solid-state formaldehyde sensor works simultaneously with a selective catalytic oxidization filter, to destroy formaldehyde molecules 500x smaller than 0.1 microns.

Powerful and quiet
The high-velocity, low-pressure system produces low noise levels of just 55.6dB.

Acoustically engineered
The Helmholtz silencer traps sound energy and reduces low frequency noise, while the motor mount reduces vibration – so the little noise you hear, is quiet even at full power.

Frequently asked questions
How noisy is the purifier?
Our latest purifier is acoustically engineered to operate quietly – even at its highest power setting. So it reduces your exposure to pollution, without disturbing you at the office or in the classroom. It records just 55dBA of sound power at full speed.
Other purifiers claim “HEPA” standard – why is Dyson special?
In Dyson’s latest purifiers, it’s not just the filter that meets HEPA H13 standard², it’s the whole purifier. So they don’t just capture pollutants, they prevent them from leaking back into the air you breathe. High-pressure seals, combined with Dyson’s fully-sealed filtration system, means our whole purifier meets HEPA H13 standard.² So what goes inside, stays inside.
Why do some competitor machines have a lower dB reading than Dyson purifiers?
Some manufacturers publish dB ratings tested at low fan speeds, which can limit purification performance.
At Dyson we measure and publish sound levels dB(A) at maximum fan speed, where purification is at its optimum.
Why does the new purifier have a CO₂ sensor?
Increased CO₂ levels can impact cognitive function. Our latest purifier senses and reports CO₂ levels and notifies when they exceed recommended levels, alerting on the LCD screen when to ventilate.

Why choose Dyson for business
¹Tested for PM2.5 purification in a 1074ft2 (41.7ft x 25.8ft) room. Results may vary in practice.
²Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode, for whole machine efficiency above 99.95%.
³Third party full machine testing based on GB/T 18801-2022 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
⁴Filter life is determined by dividing total dust load capacity by annual dust load. Annual dust load was calculated using GB/T 18801 daily mass formula. Results may vary in practice
