Powerful circulation to purify an 2860ft³ space³

Dyson purifiers don't compromise airflow for purification. Combining advanced filtration with Air Multiplier™ technology, they generate powerful circulation to draw in pollutants and projects over 290 liters a second of purified air throughout meeting rooms, hotel rooms and classrooms.³ Powerful circulation to purify an 2860ft³ space, equating to 290 sq ft.

CADR is not a measure of purification performance in a real-size room 1,008 ft³

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

Graphic showing POLAR air circulation test method

Dyson's POLAR test goes further to measure purification throughout a real-size room 2,860 ft³

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

    Two 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.

  • Senses and reports

    Detects airborne particles and gases, displaying real-time air quality reports on the LCD screen.

  • Hassle-free Auto mode

    Automatically reacts to remove pollutants from the air, increasing airflow when it needs to.

Additional features

  • Easy filter maintenance

    Changing the HEPA+Carbon filter is quick and easy, with automatic notifications for each machine on the LCD screen.

  • Cools you with purified air

    Air Multiplier™ technology delivers powerful, long-range airflow to cool you with purified air.

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?

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. 

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.

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).

Why choose Dyson for business


¹Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.

²We challenged our purifier with airborne influenza A (H1N1 virus) at an independent lab. After 60 minutes in the chamber, at maximum fan speed, the airborne virus was reduced by 99%. Real-life efficacy may vary. 

³Compared to Dyson Pure Cool purifying fan. Projects 290 L/s of air maximum setting. Tested for air projection (DTM801), purification coverage in a 81m3 room (TM-003711).

⁴Based on 12 hours use per day. Filter life varies according to pollution levels.

⁵At maximum flow rate in Purifier mode.
