Copper can be removed up to 97-98% with a reverse osmosis water filter. Cartridges using activated carbon can also remove copper from water by using adsorption.

Does RO water react with copper?

Copper is one of the materials that easily leaches into low TDS water. … RO water is low enough in TDS that it will cause copper leaching.

Does RO remove metals?

Reverse Osmosis can be performant at removing low level of heavy metals, although in aerobic conditions metal oxides can clog the membranes. Also, RO is not a very cost efficient method, unless the water salt content requires further demineralisation.
