Watts 543700 3-stage filter with EZ Push Button Sediment, Carbon, and hollow fiber cartridges have suffered and struggled to make a decision about the type of "under the sink" water filtration system to buy. There are so may types, brands and configurations that I almost just stuck to bottled water. Boy I'm glad I didn't. I purchased this unit and installed myself in about 2 hours. The taste is great, the pressure is perfect and saving the environment. I have yet to replace the filters ... hoping that is a simple and cheap, but overall I'm satisfied with this unit.
Glad that I didn't go with a simple charcoal filter. Happy and pleased that do not choose a unit of osmosis that everyone says that impoverishes the minerals in your body I saved money on a system professionally installed ...
