Pentair Pentek RFC-20BB Big Blue Carbon Water Filter, 20-Inch, Whole House Heavy Duty Radial Flow Carbon Replacement Cartridge with Granular Activated Carbon (GAC) Filter, 20" x 4.5", 25 Micron

A little expensive but worth the cost as it does remove all taste and odor from our well water.

I have a hard iron well, this filter is in place before the softener and it works very well. I change my filter every 4 months. When I swap again I'll update with pictures but this filter does what it is supposed to with very little to no water restriction. Pentair has another similar charcoal filter GAC blue solid body and the water restriction is horrible. This filter works very well. Definitely recommend!No smell, no color.This can also be used in a singular or in line filter system with no water restriction.

I have a well with more iron then I want. I have a water softener and uv filter in line with this. I started out with the pleated type of filter and within a week my water smelled pretty bad, kind of like cat pee. Was not nice taking a shower, I gotta tell you. My well company suggested this one, and for the most part it is working for me fairly well. I've got almost 2 weeks of usage out of it and most days the water does not smell, much, maybe a little like dirt, but very faint. The taste is great and the results, I can live with. I will see how it works over time, but I would expect that in most situations this is a great filter.

I contacted the Pentair company regarding a replacement filter. Verifying what I had installed by my water quality supplier, this filter was less expensive by about 50% and worked. I will be reordering.

This is a quality product and doesn’t leave any carbon residue within the big blue filter housing. Also, great in not impeding the water flow rate into the home.

Delivered on time with Care. Great product.

I was able to order this filter originally through Vine. It was the best filter we've used to date, so I went to Amazon and purchased another, just to make sure we always have one on hand. Our vacation place is on the VA coast and anyone who has lived near the water knows how skanky well water can be near the coast. This filter is truly exceptional. Our water has never tasted better. It immediately got rid of that low-tide smell typical of water in our area. We've tried paper filters, carbon filters and magnesium filters. This filter is what we had been needing. So glad I was introduced to it via Vine. I will continue to purchase more through Amazon Prime. Pricey but worth it!

This is exactly like the filters from Culligan and they are the same price so I will probably purchase them from Culligan going forward.
