Filtration

Captures and destroys with an advanced HEPA filtration system

It's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier.¹ Dyson's advanced 360° HEPA H13 filter captures 99.97% of particles as small as 0.3 microns from the air - keeping them sealed in. And the unique catalytic filter continuously destroys formaldehyde.²

Circulation

Dyson purifiers don't compromise airflow for purification

Dyson purifies a whole room - not just the air around the purifier. To purify large spaces properly, you need a combination of HEPA purification and strong room mixing. Therefore, we've designed our products with an air multiplier on top of the core filtration technology.

Air Multiplier™ technology generates the circulation power to draw distant pollutants into the machine, projecting over 290 litres a second of purified air throughout meeting rooms, hotel rooms and classrooms.⁴ Powerful circulation to purify an 2860ft⁵ space, equating to 290 sq ft.

Dyson testing goes further than the industry standard (CADR). For real working spaces.

Dyson's philosophy is that to truly purify a whole room properly, a purifier needs to sense pollutants, capture them effectively and project clean air to every corner of the room. To measure whole room purification in real-size spaces and to represent real life conditions, Dyson engineers developed the POLAR test. Based on a large room of 2860ft³, it uses nine sensors to continually measure air quality throughout the room.³

CADR is not a measure of purification performance in a real-size room 1008ft³

An additional fan boosts circulation. Only one sensor measures air quality.

No additional fans. Nine different sensors to measure even-room air quality.

Key technology

  • Fully-sealed to HEPA H13 standard¹

    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, continuously²

    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.

Additional features

  • Easy filter maintenance

    Changing the HEPA+Carbon filter is quick and easy, with automatic notifications for each machine on the LCD screen and Dyson Link app.⁶ The catalytic filter never needs replacing.

  • Heats and cools you

    Heats the room quickly with powerful air projection. Uses an intelligent thermostat so energy isn't wasted once your target temperature is reached.

  • Hassle-free Auto mode

    Automatically detects and removes pollutants, increasing airflow when it needs to. Optimizes purification and efficiency.

  • Smart technology

    Monitor and schedule purifying for each location with the Dyson Link app.⁶ And control hands-free with compatible voice services.⁷

  • Draft-free backward airflow mode

    Diverts airflow through the back of the machine. To purify the room, without feeling the airflow or cooling you.

  • Night mode

    Perfect for peaceful working environments or hotel rooms. Monitors and purifies using the quietest settings, with a dimmed display.

Frequently asked questions

What level of filtration do Dyson HEPA filters capture?

HEPA is defined as a filter that captures 99.97% of particles down to 0.3 microns and is tested using standard IEST-RP-CC001.6. Standard EN1822-5 further tests filters for capture of 99.95% of particles of the most penetrating size, usually around 0.1 microns. Dyson HEPA filters pass both of these standards. 

For reference, IEST-RP-CC001.6 is a test standard that covers basic provisions for HEPA (high efficiency particulate air) and ULPA (ultra-low penetration air) filter units as a basis for agreement between customers and suppliers.

EN 1822 is a specification used in the European Union which defines several classes of HEPA filters by their retention at the given most penetrating particle size (MPPS). 

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.
