The American Plumber WGCHD GAC Filter is absolutely wonderful! Even though the filter manufacturer recommends that the filter be replaced every three months and/or when water pressure decreases, etc.,., we used a single filter and replaced it two years later! Our water pressure did not decrease where it was noticable. After two years, the water did get a bit smelly, however, not too bad. I would not recommend replacing the filter every two years. Perhaps we got lucky. It is a wonderful product and really does make a difference in water quality!
