I have the water general unit also. It started as the 100gpd but as Jack said, it uses di resin up too quick. I've heard that you can get the good 75gpd membrane when you order it from them and they will send that one instead. If you add on a large vertical di unit, you're set to go. Since all these membranes and filters need changed so often, it really doesn't matter who's name is on the sticker and a plastic housing and metal hanging bracket doesn't really matter where it's from.
