Product review (5 stars): It does its job
This does the job we needed it to do.  Get rid of chlorine and make our water sweet again.  It lasted about a year before we noticed the water tasting bad again.  It was easy to replace this new filter. This system is affordable and works.  As soon as the old one comes out, the new one goes in, and I order another one of these so we are ready to go when a change is needed.
