Guest guest Posted February 8, 2005 Report Share Posted February 8, 2005 Isn't that a GOOD thing? ~Inga ========= I have been wondering the same thing myself. I bought 2 at Radio Shack & they give off that oder. If anyone knows please write.

BTW---it gives off a strong ozone odor---is that harmful?---If it is, why do some health practitioners recommend ozonators? Purple Raptor <purple7raptor wrote: It depends. I paid about $40 plus shipping. But you can pay a LOT more, depending on make and model, and where you buy. If you want the name of my seller, please write to me privately and I'll tell you.
