Here is a more powerful ionisator and ozone generator than described in my version-2. It is meant for continuous operation in problem spaces such as cellars with some rot & mould. It can also be operated in normal living rooms when you are not at home. But it is too aggressive for your lungs, if used continuously in inhabited spaces. It is not powerful enough to carry out short disinfection actions, for example after a burning frying pan has put your kitchen under smoke.
The transformer is from an old TV set, which still used a single rectifier instead of a tripler or even a diode-split rectifier. The latter ones you cannot use because they output positive polarity against ground, and it is very difficult to “turn around”. Here the rectifier diode was inverted to generate “Minus” at the output.
