We have used Luminous Water Solutions in the past for a different kind of system before. This time, we had a Premium Luminous Water System installed. It is working fine. We have been doing well with it. I really like this system because it gives you pure water without the electric primer system. It recharges based on the amount of water usage, and that is a real plus. With this one, we have the filters that you can actually clean so we don't have to keep purchasing filters for it. The system came with two filters so we always have one clean one, and we can clean and reuse each filter as long as there is no damage to it. Once they become damaged for whatever reason, then it needs to be replaced.
