We have been using the system for almost 2 years. And we are very satisfied with the water quality. Exactly what we need and expect. I check the water as promised for TDS and values: 12 PPM. Heavy metals are also in check. The water in our refrigerator, which is not connected to a filter, is terribly dirty: 200 and more. PS We hired someone to install our reverse osmosis filter despite many reviews saying it was easy to install. Cartridges must be changed every year.
