There is a difference between a water filter and a water purifier. Water filtration is the process of cleaning water of impurities through a homemade filtration system, with chemicals or by using a biological process. ... Although similar to water filtration, water purification focuses more on removing all impurities from the water. Reverse Osmosis

Fact: It is critically important to remember that it is the water, not the soluble or suspended minerals and other constituents that serve as a solvent and medium for the transport of nutrients and wastes to and from cells throughout the body. Water bathes the cells, cushions the brain, lubricates the joints and tissues, and regulates body temperature, as well as the body’s biochemical reactions.
In point of fact, it must be noted that the US Navy has used distilled water with less than 3-ppm TDS aboard navy vessels for more than 50 years. Submarine crews typically drink nothing but low-TDS purified water for months at a time, all with no reported ill effects. The US Army uses expeditionary (portable) RO systems to provide low TDS-safe water for its field personnel. They do not consider low-TDS water to be a problem and have no minimum standards. The US EPA conducted a project in San Ysidro, NM in which the drinking-water TDS was reduced from 800 mg/L to a range of 40 to 70 mg/L. No ill-health effects were observed during a one-year test. Many hundreds of thousands of RO drinking-water appliances have been sold residentially over the past 40 years without any reported ill health effects from the consumption of this type of water.
