How effective is reverse osmosis for improving water quality?
RO is very effective in reducing a range of home water contaminants. This is possible because the reverse osmosis membrane is comprised of microscopic pores which allow the pressurized water molecules, among the smallest molecules known to man, to pass through contaminants, and even dissolved ions are left behind. Additionally, RO systems always include sediment pre-filter that traps fine suspended materials that permanently clog the membrane. Most RO systems also include a carbon pre-filter to remove chlorine, along with other contaminants that may damage RO membranes and affect that taste, color, and odor of the water.
