This system is easy to install, very easy to use, and never wastes water. The water goes through three replaceable filters, 1.5LB KDF55, 1.5LB KDF85 and a Sediment filter which are quick and simple to change, inexpensive to operate and gives great drinking water.
Unlike a RO system, with this unit you have all of the drinking and cooking water you want with no waste of water.
