MODERATORS
As demonstraded by the ActionLab video someone else posted, "bladeless" fans in general are less efficient. The one he tested was not a Dyson and didn't have a HEPA filter.
Defining efficiency by air speed?
It was also moving more volume of air, not just airspeed. Sure I would have loved to see a fully shrouded experiment, but their experiment did show a regular fan moved air faster over a wider area, which would mean it is also moving a higher volume of air.
