We are living in an increasingly toxic world, where finding "clean" products is becoming more and more difficult. The same can be said of our water. A 2013 study found that even bottled water contains toxins, primarily endocrine disrupting compounds (EDCs): https://pubmed.ncbi.nlm.nih.gov/24015248/
Distilled water is the cleanest of all available options, and the one we should all be drinking. Bottled distilled water is not guaranteed to be safe, the best way to purify your water is to distill it at home. Investing in a water distiller will save you a lot of money in the long run, and prevent many health issues.
