Key technology

  • Fully-sealed to HEPA H13 standard⁵

    Three phases of purification sit within our fully-sealed filtration and airflow system. To trap pollutants inside, removing them from the air you breathe. Giving you reassurance that what goes inside, stays inside.

  • Destroys formaldehyde, continuously³

    Formaldehyde can emit from many types of commercial furniture and flooring over time. Dyson's catalytic filter continuously converts it into water and CO₂ – and never needs replacing.

  • Senses and reports, automatically

    Detects particles, formaldehyde and other gases, displaying real-time reports on the LCD and Dyson Link app.⁶ In Auto mode, it automatically reacts – only purifying when needed.

Frequently asked questions

How many Dyson Purifiers do I need for my business?

Dyson experts are on hand to better understand your business environment. We'll advise about which purifiers will best suit your space and budget, as well as informing you about our latest offers.

What's the lifespan of the filter in a Dyson Purifier?

The formaldehyde-destroying catalytic filter never needs replacing. And we recommend replacing the HEPA+Carbon filter every 12 months (based on 12 hours a day of use) – so this may vary depending on usage and pollution levels. You'll be notified via the Dyson Link app⁶ or LCD screen when it's time to replace the filter.

Do I need to maintain my Dyson Purifier's filter?

No, unlike some conventional filters which require changing, washing and drying each month, this isn't the case with ours. So there's no time wasted without a working purifier. Our filter is quick and easy to replace – and you'll know exactly when, via the Dyson Link app⁶ or LCD screen. Please note that the selective catalytic oxidisation filter never needs replacing.

Can multiple users control the same Dyson Purifier?

Yes, one Dyson Link app account can be used to control up to 15 connected purifiers – or an unlimited number of users can control a single purifier. It will only ever choose the most recent update. For example, if more than one person was updating the scheduling, the purifier will use the most recent change.
