I think we may agree to disagree on this oneDust is the prime problem. Water systems trap more dust than any filter can ever trap. The best is a system that traps the dust in water and then includes a filter afterwards to clean the air of any thing afterwards.
Fitting more dense filters to a vacuum cleaner can actually reduce the effectiveness of the vacuum cleaner. So, yes the hype is there with vague references to "allergens" when really it is just about the effectiveness of catching the dust before letting the air back into the atmosphere.
