Ozone can be used for many things - if used correctly.
Commercial Air - Water Pruifiers use it, you can get rid of harmful pesticide and chemical residue while cleaning your salad or "clean" the air after a big party with a lot of smokers.
Since the basic design and work priciple is more than easy I was wondering if there is a need for an Instructable?
But with Ozone not only being of concern for the enviroment in terms of smog but also being a health risk in higher concentrations I am not so sure if it is a good idea.
After all we don't want to cause any harm with our projects...
