1. Ok, the best generators anywhere, are at www.plasmafire.com $1,800 - $2,500.
2. Ozone can get rid of those odors, but it has to come in contact with the source directly. My house had mold on the outside of the house, and the ozone went right through the walls and destroyed the mold on the outside of the house. No damage with anything else.
3. Never heard of rgf units.
4. You can "blast" what ever without destroying items. Been using pure ozone (made from pure oxygen) for almost three years.
