Reverse osmosis, also known as hyper filtration, is the finest filtration available today. It is the most common treatment technology used by premium bottled water companies. It is effective in eliminating or substantially reducing a very wide array of contaminants, and of all technologies used to treat drinking water in residential applications, it has the greatest range of contaminant removal. Reverse osmosis will allow the removal of particles as small as individual ions. The pores in a reverse osmosis membrane are only approximately 0.0005 micron in size (bacteria are 0.2 to 1 micron & viruses are 0.02 to 0.4 microns).
How does Reverse Osmosis work?
30 billion plastic bottles a year are dumped into U.S. landfills and it takes 1.7 billion barrels of oil to produce those bottles. This produces some 2.5 billion tons of carbon dioxide pollution. In fact, it takes three times as much water to make the bottle than it does to fill the bottle. And for what? People pay for the perception of clean water, but in fact the quality of the water is at best unknown. RO systems are proven to remove the contaminants and it is the “green thing to do”.
