Purifies

Cools you

Heats you

Dyson purifiers have intelligent sensing. Three sensors work in harmony to constantly monitor your air quality – interacting with our unique algorithm to diagnose and report pollutants in real-time.

It also has two layers of purification to thoroughly clean your air. HEPA H13 and activated carbon filtration captures gases and 99.95% of pollutants as small as 0.1 microns.2 And the whole purifier, not just the filtration system, is fully-sealed to HEPA H13 standard3 – so what goes inside, stays inside.

Only Dyson purifiers have Air Multiplier™ technology, to purify the whole room.4 It generates powerful circulation, drawing pollutants from every corner into the filters and projecting purified air throughout the room. Additionally, Air Multiplier™ technology projects purified, heated air throughout the room.2 Once your target temperature is reached, heating automatically stops.In warmer weather, a powerful stream of purified airflow can cool you down.

Removes 99.95% of ultrafine particles1

Purifies the whole room2

Fully sealed to HEPA standard – what goes inside, stays inside 3

Automatically senses, reacts and displays real-time air quality

Control your airflow 

Jet axis control allows two oscillators to guide airflow through apertures at a 90° range.  

Senses pollutants and allergens 

Detects particles and VOCs in the air. 

Captures gases and odours 

An activated carbon filter captures gases such as benzene and NO2 5 

Removes allergens and pollutants 

Purifies by removing 99.95% of ultrafine particles2 

Improve the air quality inside your home 

Pollution isn't just a problem outside. In fact, the average home can be up to five times more polluted than the air outside3. On top of this, dry air from central heating and air conditioning can affect the air we breathe. Fortunately, we have a solution to both – all year round. 

Senses and reports, automatically 

Three sensors constantly monitor your air. Our unique algorithm diagnoses pollutants at a molecular level – reacting to purify and humidify before displaying live air quality in real-time reports.  

Captures pollutants with advanced HEPA filtration  

A carbon filter removes gases such as benzene and HEPA filter captures 99.95% of particles as small as 0.1 microns.2 

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 ley 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 Dyson Link app. The catalytic filter never needs replacing

Caveat

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.

3 Dyson’s product filtration efficiency at MPPS achieved 99.95% H13 HEPA level defined by EN1822, compared to the purifiers based on market data [from March 2020]. Product filtration efficiency tests conducted at IBR US within a chamber specified in ASTM F3150, under max mode and using particles challenged by DEHS oil according to EN1822. 4
