They buy safety around children and ease of cleaning rather than more airflow, and they are rarely the quietest option at a given air volume.
What the money buys
A housing with no reachable blade, a smooth surface you can wipe in a few seconds, and a column of air without the chopping quality some people find tiring over a long evening. Those are real benefits and they are the honest case for the format.
What it does not buy
More air per euro. The compact impeller that makes the shape possible has to work harder to produce a given flow, and noise follows work. At the same airflow, a conventional fan of similar quality is usually the quieter one.
The cleaning argument is stronger than it looks
A bladed cage is the reason a great many fans end up replaced rather than cleaned: dust bonds to the blade edges and the cage has to come apart to reach it. If that is what killed your last fan, the premium has a practical answer behind it.
The airflow figure is the one to look for
It is also the one these listings are least likely to print, because the format does not flatter it. Where a maker does give cubic meters per hour, compare it against a conventional fan at the same price before concluding that the premium bought anything beyond the shape.
What we would not do
Pay the premium purely for noise. If quiet is the goal, compare published figures at a stated speed and distance, and treat the format as irrelevant to that question.
The questions that keep coming up
Is there really no blade?
There is one, in the base, behind a grille. What the design removes is any blade you can reach — which is the point of it — rather than the blade itself.
