Also, I want to mention that I firmly believe in the treatment but UV ozone is the LEAST effective against fungus. It is extremely effective as an anti-viral (I've had EBV problems in the past), anti-bacterial (I have dysbiosis and possible pathogenic strep and staph in my stool tests)and anti-parasitic (I most likely have some type of protozoan parasite).
So for the lucky few who only have a candida/fungal/yeast issue, it is unlikely to be such a large help. But most of us have at least 2 out of the above 4 problems anyway.
