RO filter systems do remove a lot of contaminants. However there are many downfalls to this system...
1. Most RO Systems have 4 to 6 small filters that need to be replaced each year. The Acuario system only has 3 filters that need to be changed annually.
2. Reverse Osmosis wastes a lot of water. An average RO purifier wastes approximately 3 litres of water for every 1 litre of purified water. Acuario systems waste ZERO water.
3. RO water filters remove trace minerals and other beneficial substances found in water that your body needs like calcium, manganese, iron and other important nutrients. This is why RO water is considered by many in the natural health world to be dead water and it is said that demineralized water is detrimental to general health due to vitamin and mineral depletion. Acuario systems retain all benefical minerals which are present in the water.
4. Major downside regarding RO Systems is that because the RO filtration process strips out all of the good nutrients in water, some RO companies think they can add a "Remineralization Cartridge" at the end of the filtration process to replace all of the good stuff that mother nature originally had in the water (Yikes!). Also, most of these "Remineralization Cartridges" that we have seen in the marketplace come from China. Generally we have found that when scientists or business people try to mimic mother nature, they miss badly.
