Device uses movement of ions to generate airflow without any moving parts like in iPads and MacBook Air.

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.
