Membrane performance is based on 65 PSI and 77°F water supply. This Value Pack is for You The 50 GPD RO Buddie and 50 GPD RO Buddie+DI both use a 450 CC Flow Restrictor. If your RO Buddie has the 450 printed on the Flow Restrictor, this Value Pack is for you. Easy View Sediment Cartridge The translucent polyethylene sediment cartridge housing makes it easy to view the 5 micron filter and know when it's time to replace. Review: Perfect - Fast shipping and good product Review: Love this - best value for RO water system - After some online research, I learned that this system is perfectly suitable for human water consumption, but it’s marketed for fish tanks primarily. I bought it and have been using it for nearly 2 years now. I don’t have a TDS meter to measure input vs output, so I’m trusting it’s doing it’s job. The water tastes great coming out, due to the large carbon filter. I highly recommend this. ## Features - RO/RODI FILTER CARTRIDGES PACK RO Buddie replacement cartridges pack includes (1) Carbon Block Filter, (1) Sediment Cartridge, and (1) 50 GPD TFC Membrane Filter. - SEDIMENT CARTRIDGE The Sediment Filter Cartridge captures and reduces unwanted particulate material such as sand, silt, and rust from water which affect the taste and appearance of your water. - CARBON BLOCK FILTER The Activated Carbon Block Filter removes 1 PPM chlorine for up to 2,500 gallons of water and conditions the water prior to the RO Membrane for up to six months. - TFC MEMBRANE FILTER Thin Film Composite (TFC) Membrane for standard RO systems and the RO Buddie features polyamide membrane material with a negative charge that removes harmful substances. - INLINE CARTRIDGE DESIGN Inline design makes it easy to plumb into many different types of filtration needs.
