I have terrible problems with my asthma at night - with my Dyson Air Purifier my breathing has radically improved and I sleep so much better 10/10

  • 1 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 airborne concentration in the chamber was reduced up to 99.9 %. Real-life efficacy may vary.
  • 2 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 (a surrogate to test SARS-CoV-2) at an independent lab, using a 30 m3 chamber. After 90 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99.9 %. Real-life efficacy may vary.
  • 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.
  • 5 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463)
  • 6 Gas capture rates may vary.
  • 7 In maximum setting. Tested for air projection, purification coverage in an 81m³ room and heating performance in a 35m³ room.
  • 8 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%.
  • 9 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.
  • 10 Refer to the MyDyson™ app for compatible voice services.
  • 11 After reaching target temperature and maintaining it. Tested in a 35 m³ chamber when using the hot air mode and the product setting temperature is 25 °C. Comparing with continuous operation with power consumption of 2050W. Real life results may vary depending on room insulation.
  • 12 Based on the awards for electric heaters received by Good Housekeeping 2023.
