I have never heard of that product, but this guy, Glenn Meder, has the best and most thorough knowledge of any expert I’ve ever heard. I attended a webinar of his last month and learned so much about all the different ways to purify water, what purifiers do NOT remove from water, etc.
This upcoming webinar is free,although towards the end Glenn will talk about his invention, a survival still for distilling water.
