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

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.
