dead down wind uses enzymes, I tested it against some others using cigar buts and it does much better. I also bought a commercial ozone machine of ebay for 80 bucks, because my suv smells like catfish. Ozone is poisenous so I wouldn't recommend hunting with it like some do. but i will be testing it good this year to treat my suv with hunting equipment in it. maybe ill post my results on this machine a month into hunting season.

a while back I ordered a small ozone generater off ebay for 3 bucks shipped from china, It plugs into the lighter and puts out 3mmg per hr. leaving it plugged in all the time seems to have killed the moldy catfish smell. that and the dog sniff test ive read about got me to buy the 3500 mmg unit. if it works good i might look at making a battery powered unit for around 50 bucks, seeing that hunting ozonics usually cost 400. and who knows what ther'e putting out per hr.
