We decided to try to make our drinking water better without buying a water softener or water filter for our water line.  The filtration system was easy to set up.  Just remember that the rubber o-ring goes in the top and the groove line on the threaded faucet goes on the bottom for the unit to clink into.  The well water did taste better.  We also tried it at our neighbors since they have sulfur water.  It took the sulfur water taste our of their water.  They are also looking into this system.  We do not know is how long the filter will last which could depend on water use and the type of water.  The system is a bulky but I am not sure how to make it smaller with what the filtration system need to accomplish.
