2.5 x 19” reverse osmosis membrane for all Little Wonder 160/200, 12 or 24 Volt DC powered units with two (2) pressure vessels. This membrane includes a 2” extension tip so it will also fit standard 21” pressure vessels.
Note: This part replaces Village Marine part number 33-2519L. This new design will allow your Little Wonder 160/200 to produce water with a lower TDS content than with the old design.
