Certification: NSF

Water is classified as drinking when it doesn’t contain any microorganism, parasites or other substances, in such a quantity to represent a potential danger to human health.

Its organoleptic characteristics must be acceptable to the consumers, including clarity, transparency, the absence of colors and any anomalous odors.
