It lowered TDS from the mid-upper 20s to the low 20s. For that alone it's worth the cost.But after thinking that it also lowered waste at first, I concluded that I must have made a mistake, because I tried it several times since; each time drawing 1 gallon of water at the faucet, and each time getting 5 gallon waste.
