Pentek GAC-BB

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. This Big Blue filter is also known as the GAC-BB, GACBB, and GAC-BBS by Ametek, Culligan, and US Filter, as part number 155153, and as the American Plumber WGCHD Heavy Duty GAC Water Filter Cartridge. 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.

Note: The packaging for this item is changing. Depending on availability, you may receive Pentek or Pentair on the label.

Excellent filter to use in whole house systems needing to filter carbons and magnesium out of water. It works great.

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!
