Pentek C1-20BB Big Blue Water Filter, 20-Inch Whole House Dual Purpose Powdered Activated Carbon Replacement Cartridge, 20" x 4.5", 5 Micron, Black

This filter really works. I live in Fort Lauderdale and for the past 10 years, I was using a different brand and I won't say the name of the Company (which begins with the letter "A"). The price of their filter is twice the cost of this brand (plus shipping), so I thought I would try this filter just to see how it worked. Well, for the past 10 years, our drinking water was clean of any noticeable sediment, however it was always a little yellow. The new Pentair filter takes out all of the sediment AND OUR WATER IS CRYSTAL CLEAR! I am not sure if you can imagine how happy I am with these results. Thanks, Pentair.

This filter is terrible. After using this filter for approximately three weeks the water in our toilets was black and had an awful smell. Replaced the charcoal filter with the type filter we were using and no more black or smelly water. Seller refuses to admit there is a problem with the filters.
