I have a di resin, carbon, and a sediment filter free. Ran into too many problems with my old rodi unit so I just bought a new rodi and no longer need the old one. Used the filters for only one day. The membrane is older so I'm just gonna throw that out. If you want my old unit I think it just needs a new restricter but in not entirely sure what else it may need. The housing is brand new you can have that for free as well if you want. It's a spectapure 90 gpd.
