The Pentek GAC-BB - 10" Big Blue Water Filter - WGCHD is a Granular Activated Carbon (GAC) water filter that reduces bad tastes and odors, as well as chlorine taste and odor, in your water. The GAC-BB filter design promotes maximum carbon/water contact time, therefore maximizing filtration efficiency.

The Pentek GAC-BB needs to be replaced every 3 - 6 months, or based upon the return of bad taste or odor or a decrease in water pressure.

:) Awesome!!!!

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!
