Air valve motor

The valve mechanism is driven by a brushless stepper motor, to allow remote actuation and switching between Diffused mode and Fan mode.

Air Multiplier technology

Projects a long-range stream of smooth air. No need for blades.

PTC plates

Air circulates between the plates and external casing, to heat the air as it leaves the machine.

Gas and particulate sensors

Measures and detects particles and volatile organic compounds in the air.

Real-time LCD screen

LCD screen reports indoor air quality in real time. The laser-etched display window is made from a single piece of impact-resistant polycarbonate shell.

360 HEPA H13 filter

9 metres of borosilicate microfibres, pleated over 200 times, captures 99.95% of pollutants as small as 0.1 microns.2

Activated carbon filter

A layer of carbon captures gases1 such as benzene and NO2.

Pollutant sources in a living space and kitchen

Poor air quality isn't just a problem outside.
It's a problem inside too.

From plant pollen and cooking fumes, to VOCs and benzene found in sprays and candles, our homes can trap pollutants in the air. That's why Dyson purifiers automatically sense and remove them.

Senses and reports, automatically

Three sensors constantly analyse your air, while our unique algorithm cross-checks data every second. To precisely monitor, display and react to your air quality.

The purifier is fully sealed to HEPA H13

To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier. So what goes inside, stays inside.

Frequently asked questions

What is new about the Dyson Purifier range and how is it different to other purifiers?

Dyson engineers are perfectionists. Channelling our relentless dissatisfaction, we have re-engineered the Dyson Purifier range to be our first purifiers fully sealed to HEPA H13 standard. Capturing 99.95% of ultrafine particles and preventing pollutants from leaking back into the air you breathe.

How often should I replace my filter?

We recommend replacing the HEPA+Carbon filter every 12 months. That's because over time, filters can get clogged with pollutants, and even let unpleasant odours back into the room. The machine will alert you when it’s time to change filters. A filter life reading can be found on the LCD screen and via the MyDyson™ app. The catalytic filter never needs replacing.

  • 1 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463)
  • 2 In maximum setting. Tested for air projection, purification coverage in an 81m³ room and heating performance in a 35m³ room.
  • 3 Particle 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%.
  • 4 Gas capture rates may vary.
  • 5 Requires device to run app, Wi-Fi or mobile data, Bluetooth 4.0 support, and iOS version 14.0 or Android version 8.0 (or above). Standard data and messaging rates may apply. App control doesn’t apply to heating.
