Cleaning and Stain Removal - Ozinator, a good thing?

In another thread I am trying to find out the best way to clean a house that has been smoked in. One of the areas that I am concerned about is the duct work. So I have done some research on ionizers (which appear to be pretty useless) but in the process I found some information on ozinators, which apparently work a whole lot better. Looking for any information, the good the bad about such units. I have found them that attached to your forced hot air system that seems like the way to go or there are other that actually have far greater area coverage that are stand alone. For about $350 would it be worth having in general and part of the heating and cooling system?? Would it be better to go to a local rental place and rent the biggest badest unit I can find and put it in the house with the air on for a couple of days?? Any help would be appreciated.

Thanks

You may just want to rent it. I have heard they work miracles when used properly.

You might want to read what the EPA says about ozone machines at http://www.epa.gov/iaq/pubs/ozonegen.html

Wow, that changes what I thought was a good idea to a really bad idea. I already have extensive lung damage. I couldn't determine if you were not in the house and then aired it out good if you would then be safe, it seems that other chemicals are created that could be more harmful than the original problem and they talked about wiring and rubber and other products that probably exist in the house being degraded by the ozone. So are we just screwed if there is a problem with the duct work having an odor problem, I can't imagine how it wouldn't. My thought is that if a problem existed it would be in the cold air returns in the rooms that were smoked in and I assume would be stronger the closer to the room and diminish as it got closer to the furnace. If that is true, the problem would be either cleaning or replacing those sections. Any idea how to clean them?

Perhaps if you posted in the HVAC Forum that the experts there could tell you about cleaning ducts.

Thanks, I will do that.
