These 40" RO Membranes are designed to operate at extremely low operating pressures making them the perfect choice for the Tucker® RO/DI systems as well as any other system on the market.

Consider changing your RO membrane when it has begun to remove less than 80% of the impurities in the water. The fewer impurities the RO can remove, the more you will spend on DI filter replacements. Fits the H2Pro as well. This is NOT the replacement RO membrane for the 4060 system. The correct replacement RO membrane for the 4060 is the 4 X 30" REVERSE OSMOSIS MEMBRANE
