*Dyson purifiers were challenged with airborne influenza A (H1N1 virus) and MS2 bacteriophage at an independent lab, using a 30 m3 chamber. After 60 minutes at maximum fan speed, the airbone concentration in the chamber was reduced up to 99.9%. Real-life may vary.
*Dyson purifiers were challenged with airborne SARS-CoV-2 (the virus that causes COVID-19) at an independent lab, using a 0.37 m3 chamber for 90 seconds. Dyson purifiers were also challenged with Phi-6 bacteriophage at an independent lab, using a 30 m3 chamber. After 90 minutes at maximum fan speed, the airbone concentration in the chamber was reduced up to 99.9%. Real-life may vary.

Filtration
Captures and destroys with an advanced HEPA filtration system
Inadequate ventilation can help outdoor pollutants, like PM2.5, penetrate indoors. Dyson's advanced 360° HEPA H13 filter captures 99.95% of particles as small as 0.1 microns⁴ from the air - keeping them sealed in. And the unique catalytic filter continuously destroys formaldehyde.³
Circulation
Powerful circulation to purify an 81m³ space¹
Dyson purifiers don't compromise airflow for purification. Combining advanced filtration with Air Multiplier™ technology, they generate powerful circulation to draw in pollutants and project over 290 litres a second of purified air throughout the room.
Dyson testing goes further than the industry standard (CADR)
Dyson engineers designed the POLAR test to challenge the industry test standard – measuring filtration, sensing and circulation to ensure the whole room is purified properly.
CADR is not a measure of purification performance in a real-size room 28.5m³
An additional fan boosts circulation. Only one sensor measures air quality.
Dyson's POLAR test goes further to measure purification throughout a real-size room 81m³
No additional fans. Nine different sensors to measure even-room air quality.
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
The Dyson catalytic filter continuously traps and breaks down formaldehyde¹ molecules into water and CO₂. And it never needs replacing.
-
Senses and reports, automatically
Detects particles, formaldehyde and other gases, displaying real-time reports on the LCD and Dyson Link app. 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.
-
Diffused mode
Diverts airflow through the back of the machine. To purify the room, without feeling the airflow or cooling you.
-
20% quieter
Acoustically engineered to reduce turbulence, so it's 20% quieter than the previous model.
-
Smart technology
The Dyson Link app lets you see which particles have been captured, set schedules and more.⁶ Control hands-free, using compatible voice services such as Amazon Alexa, Google Assistant or Siri.⁷
-
50% longer cable
For ease-of-use in commercial environments.
-
Additional remote control
Your purifier comes with an additional remote. One can be stored neatly on the top of the machine – the other kept close to hand or stored safe for peace of mind.

Frequently asked questions
The Dyson Purifier Cool Formaldehyde has all of the capabilities found in our advanced purification products but goes a step further to detect and destroy formaldehyde. An added solid state-sensor precisely detects formaldehyde, while our catalytic filter breaks it down into two safer molecules – carbon dioxide and water.
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.
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.
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.
- 1 In maximum setting. Tested for air projection (DTM 801) and purification coverage in an 81m³ room (TM-003711).
- 2 Whole machine tested by independent third-party laboratory Airmid (Ireland) in 28.5m³ test chamber pre-conditioned to 20±3C and RH 50±5%. Influenza A (H1N1) aerosolised in the test chamber and airborne concentration observed for the duration of 60 minutes under maximum Fan speed. Achieved 99% efficacy but real life efficacy may differ depending on actual environment and Fan speed. Tested on Influenza A (H1N1) only.
- 3 Third party full machine testing based on GB/T 18801-2015 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
- 4 Tested for filtration efficiency at 0.1 microns (EN1822). Gas capture rates vary.
