Hi Carmine,
I basically just wanted to clarify that dust mites not bacteria are killed during vacuuming and that I never stated or implied that vacuuming in any way does in germs. That said, the real issue is to what degree are dust mites done in with UV light.
So Halo and its UV light can kill germs, dust mites and their larvae, yes. Neither Halo or Oreck clarify and plain facts woulds better cinch the deal. During that few seconds, per square foot I assume, has 10 percent, 50 percent or 75 percent of the existing little meanies on your floor eradicated. Terms like "some" and "many" aren't very helpful to a consumer possibly deciding to go to great expense to solve a perceived problem.
There's no way for the average user to monitor the effectiveness of a device like this. Nor would I see reason to go out and buy one especially if it bears a high price tag just on the makers say so. If the maker said x-amount of seconds per x-amount of area assured x-percent of kill, I'd be fine with the whole thing. Unfortunately, they do not.
You merely end up with people breezing around the house with a machine that may well make no significant difference affecting the problem it was bought to solve.
Another matter not discussed is how often must such a machine be used to lower and maintain a lower infestation level. Good to know but not established.
