How effective is reverse osmosis filtration?
RO is the most convenient and effective method of water filtration. It filters water by squeezing water through a semi-permeable membrane, which is rated at 0.0001 micron (to over 10.000 at a millimeter!). It is the only technology capable of desalinating sea water, making it into drinking water. Non-RO water filters are much less effective, and the pore size on these filter media are much bigger, generally 0.5 – 10 micron. 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 safe compared to reverse osmosis filtration.
