I do not believe things I read on the internet, that's why after a lot of research I decided to contact somebody who has physical experience in the matter. I trust that his experiences prove this is a safe method.There are plenty if advantages, including RO and distilled water to be free of, in addition to minerals, any possible toxins or viruses that may lurk in water. Bottled water is far from completely safe by human standards. Dechlorination and purification tablets do not take care of everything. Distillation covers all that, but the only downside is the rumored leeching effect on amphibians. Since this, in practice, is not the case, this is the safest method.
