I just want to say: I love the idea of fan blades that are themselves filters. One of the central challenges with air purifiers, is that a lot of energy is “wasted” trying to push air through filter materials. With fan blades, I think essentially all of the energy would be used either for filtering or for pushing air, in a sense this purifier would be 100% efficient? Also I worry (only a little bit) that Jeff’s ceiling-fan idea might increase the load on the motor, and this would seem to totally eliminate that concern.
Though in practice, this seems hard. I guess you’d want some rigid fan blades with “slots” you could put commodity filters in a standardized shape? Not sure there are any cheap standard filters that would make this easy.
