Reverse Osmosis (RO) systems remove all salts and microorganisms (bacteria and viruses) from water with an effectiveness exceeding 99% and produce virtually distilled water. However, complex volatile organic compounds (aromatic and chlorine-organic), which are known carcinogens and especially harmful for human health are removed with an effectiveness of only 60-70%. Also, organic fibers used in the membranes of RO systems are an additional source of water contamination with organic compounds.

Ion-Exchange (IE) resins are used to remove hard salts, heavy metals and some non-metallic elements such as phosphorus and nitrogen from water. The ion-exchange resins are complex polymers that decompose over time and require to be periodically regenerated by sodium chloride solution. The products of their decomposition also contaminate water. This kind of contamination is difficult to detect and is rarely controlled by authorities responsible for the safety of water supply.

Both RO and IE water purification systems violate the healthy mineral composition of water and contaminate water with dangerous organic compounds. The artificial re-mineralization of water by adding salts to the distilled water is very ineffective because the natural ions reside in water in an aquated state. The process of ion aquatation is extremely slow (it takes about 100 hours) and the added salts have no chance to participate in normal bio-chemical reactions in the human body.

The intake of water with unbalanced mineral composition adversely affects all important biological solutions in a human body, such as blood plasma. Drinking de-mineralized or slightly mineralized water may lead to serious illnesses and permanent damage of vital organs and systems.

Unlike RO and IE filters, AquaNano™ HRCM-based water purification systems preserve the original healthy mineral composition of water. AquaNano™ filters are also extremely effective against any kind of contamination by organic compounds.
