Tony, I've bought membranes before that said 25 gpd on the outside of the box, but the label that the bag that the actual membrane is in says 50 gpd.
I don't think that there is any indication what the rating is on the membrane cartridge itself. Maybe you can tell a difference from the number of "wraps" of the membrane tissue or something....I dunno....  Mitch
