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

    Bladeless Dyson’s have the fans hidden, as far as I know. But they still have a bladed fan in there.

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

                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?

                  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

                    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.

                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.

        I recently watched some YouTube video that debunked that claim. They are basically pointless.

        Edit: https://www.youtube.com/watch?v=ySSo5PmZZJM

        It actually works better when You take the inner fan out of the casing. So they are actually a scam.

          Not a dyson

          Not a proper test, air volume not measured - only speed. The point is to not have fast air so this only confirms the concept works

        They literally generate as much as that small fan in the case can generate.

        With the aerodynamics of the case it’s just a matter of converting higher pressure into lower pressure with higher (& a bit more laminated) airflow.
