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

    They do not. For a given power input they produce less airflow at lower velocity than a regular fan. They’re a complete scam.

        You made a claim first, so you should provide your citation first as well.

            Advertising for a product isn’t a citation. That article literally just repeats Dyson’s own claims. Do you have anything that actually tests that claim?

                You made an assertion. If you are unable to provide supporting evidence, we can assume that your assertion is incorrect without needing to prove anything.

              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.

            They’re “bladeless” fans are just regular fans with more steps. Those added steps introduce inefficiencies. Simple as that. If you wanted to make a fan more efficient, you could add a shroud close to the blades, but the energy cost of electric fans are already low enough that it really doesn’t matter.
