1Particle 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%.
2HEPA filter tested to EN1822-5, by an independent testing laboratory, under prescribed test conditions.
3Applies in Eco mode when using a non-motorised tool.
4We challenged our purifier with airborne influenza A (H1N1 virus) at an independent lab. After 60 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99%. Real-life efficacy may vary.
5Tested for filtration efficiency at 0.1 microns (EN1822). Gas capture rates vary.
6Third 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
7Requires device to run app, Wi-Fi or mobile data, Bluetooth 4.0 support, and iOS version 10 or Android version 5 (or above). Standard data and messaging rates may apply. Refer to the Dyson Link app for compatible voice services.

9Tested by an independent laboratory, under prescribed test conditions, using the bacteria Brevundimonas diminuta and the virus MS-2 coliphage.
10The environmental impact of electrical appliances and paper towels was measured by Carbon Trust. The calculations were produced using the software Footprint Expert Pro, based on product use over 5 years and using weighted averages of individual countries of use. Dry times for product were evaluated using DTM 769.

12Suen et al. 2019 SR and based on bacteria in air and aerosols (0.3 to >5 microns) measured during hand drying in 28.5 m³ test chamber, in a study conducted by independent third-party laboratory.
13Increase in suction power is only experienced in Auto mode when triggered by increased concentration of dust according to Dyson internal test method. Technology is optimised for Auto mode with a powered cleaner head. Particle size and densities vary.
14Quantity and size of dust displayed on screen varies depending on usage. Examples shown may occur within one or more displayed size range.
15Suction tested to IEC62885-4 CL5.8 and CL5.9, tested at the flexible inlet, loaded to bin full, in Boost mode against the cord-free stick market.
16In Eco mode on hard floor. Additional battery available to buy separately.
