the ozonated oil remains ozonated for months and takes 24 hours to process.
Ozonated water takes about 10 minutes for 10 ounces.
Lightly ozonated olive oil takes about 15 minutes and can be used internally for things like Hulda Clarkparasite cleanses.
Heavily ozonated olive oil takes over a month running your machine 24/7 and is use on the skin only. Only a heavy duty machine can do it and you have to watch it as it will foam over. Better to buy it on line.
