MODERATORS
I don't think you two are even contradicting each other. The airflow going through the base can be 15x smaller than the total result, but also require more energy than just using a regular fan that moves that amount of air.
Total airflow and efficiency are two independent things.
Disclaimer: I have no real data on how Dyson fans work.
Of course, it is a purifier, it is hard to get high volumes of air through the HEPA filter
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.
