    Haven’t looked at them in a while, but I know the aquarium ro filters produce 1:1 waste: water. Could certainly be more efficient now, but I haven’t researched in a while

      there are different systems with different efficiency ratings. However even the worst don’t use much water - you don’t drink much water in a day.
