It should be OK
I am not that expert with chams but I do am a chemist so from my chemistry knowledge there should be nothing in the Ozonated water that can be harmful
The water should be fine, Ozone degrades fairly quickly in water and becomes oxygen. It is a type of filtration which oxidizes heavy metals and contaminants in water and by the time it gets to you there should not be any ozone left in the water. If you are worried about it just let it stand for 24 hours before using it.
