I had purchased a Csonka smoker cloaker. And that is all it is a "cloaker". if you are thinking of purchasing any ozone producing products, go to the EPA website and do some research. They have independent test results that might make you think twice about using ozone. They do nothing to clean active smoking, but will mask the smell afterward. So unless the other half is out for a while they won't help, the smoke will permeate the house. You can accomplish the same "masking" with candles and spray much cheaper. They even sell an ozone spray called Ozium, sold in auto stores. I took the Csonka back and purchased a hepa filter air cleaner that helps with the active smoke(smoke can still be smelled upstairs in the house) but cleans the air of contaminants. I am going to try a window exhaust fan next to see if I can re-direct most of the smoke outside. Hope this helps........
