It's our business to understand air pollution, so yours doesn't suffer
Workspaces can harbour pollutants such as viruses, bacteria, Volatile Organic Compounds (VOCs), pollen and formaldehyde. Everyday items such as cleaning products and printers, furniture and flooring, can release potentially harmful microscopic particles, and remain in the air for many years.³
Dyson purifiers remove these common pollutants from commercial environments
Paint, varnishes and printers
Traffic, building materials and furniture
Benzene and VOCs
Fumes and cooking
Pollen, dust and allergens
Bacteria and mould
Engineered to purify large spaces
Fully-sealed to HEPA H13 standard to capture 99.97% of pollutants as small as 0.3 microns. Purifying rooms up to 1000ft², 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 standard – 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.
The HEPA filters contain 69 feet of borosilicate microfibres, pleated over 450 times, and lasts up to 10 years.⁴
Activated carbon filter
4.6million ft² of activated carbon captures VOCs, and lasts up to 4 years.⁴
Single button operation
Two airflow speeds to increase or decrease airflow when needed.
Frequently asked questions
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.
In Dyson’s latest purifiers, it’s not just the filter that meets HEPA H13 standard, 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.
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.
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.
