⁴Tested for air projection (DTM801) and humidification (TM-002110).
⁵Requires 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 MyDyson app for compatible voice services.
⁶Fan, not air conditioning unit.
⁷Tested to DTM-801, in fan mode, at speed 10.
⁸Tested to Dyson test method TM-003387. In a 3 cubic meter test chamber, at fan speed 10, at third-party test laboratory (Fraunhofer WKI), comparison against regular activated carbon performance.
⁹Third party full machine testing based on GB/T 18801-2022 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
¹⁰Humidifier water tank sterilization system tested on S. aureus, E. coli, P. aeruginosa and B. subtilis. Water tank was inoculated with live bacteria. Samples taken of the humidification water after the first 87mL of flow were compared with initial inoculated water, showing 99.9% reduction in viable bacteria.
¹¹Based on fan speed 1.
