> Dyson describes the Cool-Me as ‘bladeless’, although that isn’t really the case – rather, the air-moving elements are concealed in the centre of the unit. isn't that the case with all of Dyson's 'bladeless' fans?

yes, well for all new ones but a bunch of years ago there was some blameless fan which worked somehow else (electric charges or similar???) and had the side effect of them emitting ozon this is why if you google dyson+ozon you will find a lot of articles telling you in various details "no they don't produce ozone", because at least some dyson like fans did produce some amount of ozone in the past. Idk. if that also applied to some old dyson products.

  There were some other brands that tried it but the airflow is much weaker and has ozone problems. Maybe Ionic Breeze? It was a Sharper Image type product. The Dysons do have regular bladed impellers in the base, but by expelling the air in a ring shape take advantage of viscosity to pull air around the ring for an added flow. My main reason for preferring the Dyson type fan is the noise they make is a soothing white noise, instead of the helicopter-like beating noise the box fans make.

    There are other brands that make quality quiet fans. My Vornado runs 24x7 and on minimal setting is inaudible, on second setting is very quiet. And it costs way less than a Dyson! I have two units in the house, and when I ordered second unit I got a defective one - probably fan was not balanced. It was making noise like normal fan. I exchanged it on Amazon, and boom - second quiet fan in the house.

It is the case, but people pointing this out like some kind of gotcha are intentionally omitting that the reason they call them ‘bladeless’ is because almost all of the airflow generated by the fan doesn’t come from the pedestal, but from the induction and entrainment caused by the airfoil.
