Do you have a bad odor that you are trying to eliminate? Perhaps you should consider removing it like the pros with a Enerzen Ozone Generator. Unlike many methods, using a ozone generator does not mask odors, but it chemically destroys them!

However, is using an Ozone Generator the right thing for you? Ozone is a pretty powerful irritant to your lungs so I certainly can't recommend it unless you are prepared to take all the necessary precautions.... these include (although there may be others)

1- Vacating the room and making sure no one or pet enters the room until after the Ozone has cleared
2- Removing all plants and anything "living" that you don't want harmed.

Once the room has been treated, and the ozone has cleared, the room will smell fresh... similar to smell after a lightning storm (lightning produces ozone).
