If you have a reverse osmosis system that utilizes proprietary cartridges and membranes, which are very expensive, then a better choice is to replace it with the US Water Aquapurion 5-Stage Module. It is also ideal for applications where you may not need a tank or just want to fill an atmospheric tank. NOTE: This is NOT a complete system. It does not include a tank, tubing, or a faucet. It does include all the filters and membrane. It is for consumers who want to replace their RO module only and already have a faucet and/or a tank.
