I agree with the caveman aproach in a pinch. I'm for any alternative to get it done. When time permits though, to purify larger volumes than is needed straight away Ozone makes sense. Among other uses, Ozone can be used to keep produce fresh longer. And temper flour. Or keep pests out of the pantry. There are tons of ways to put Ozone to work when Stuff hits the fan. Learning and practicing now makes sense.
