If you are intresting in any RO system get kinetico the best water to use.

Any one else use kinetico?

Does these rejection rates apply to RO/DI units that use booster pumps to obtain 100GPD? I was looking at the Vertex Putatek model that says they get 1:1 waste water production. Right now I use a Kent Maxxima 60GPD model and it seems descent.

Booster pumps get you from 1:8 up to 1:4 .....good: rejection

My manual for my Kent Max60HiS states that the "Waste to product ratio" is 3:1 and it doesn't have a booster pump, do you think the manual is that far off? I've never filled two buckets at the same time to compare. The Vertex Puratek (100GPD model) claims nearly 1:1 product to waste water ratio, but with it's booster pump will the rejection rate still only be 90%? Does the booster pump have no effect on the membranes rejection rate? Just curious because the Vertex has built in TDS meter, Auto shut off, pressure gauge, etc for a pretty descent price.
