What is RO (Reverse Osmosis) and how effective it is compare to other filtration methods.

RO is the finest, most convenient and effective method of water filtration available today. Reverse Osmosis refers to the process of forcing water through a semi-permeable membrane under pressure, which is rated at 0.0001 micron. This is the technology used to make bottled water. Non RO water filters are much less effective, and the pore size on these filter media are much bigger. They can filter out coarse particles, sediments and elements only up to their micron rating. Anything finer and most dissolved substances cannot be filtered out. As a result, water is far less clean and less safer compared to Reverse Osmosis filtration.
