Dyson HP7A Hot & Cool Purifier

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.

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

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.

³Dyson’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
