I have already opened the package so I can't return it. Also, I am in Canada and I got it from the UK. We dont have Walgreens here. The stores around here carry all the same brand for steam distilled and they are all ozonated. But thanks for the reply. Beth
Have you considered returning the CS generator you purchased and getting a silver puppy? Walgreens' water works well. I don't know what is in it. Good luck. PT
