The best filter ever!
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!

Perfect fit for my whole house filter system
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.

Whole house filtration system
I just finished installing a complete whole house water filtration system. I used only pentek filters and housings. I'm very happy with the performance of my system and how well it all went together. Here's a breakdown of the all the components I used in my system. I went to great length researching what works and found it wasn't easy going thru each pentek filter and it's function. The goal was to reduce some sediment, iron deposits from old iron pipes and remove any chemical taste. The water tastes great now and is crystal clear. Components: -Pentek Big Blue 20" Filter Housings -Housing Bracket for Big blue 10" and 20" filter Filters IN ORDER: 1-Pentek DGD-2501-20 Spun Polypropylene Filter 20 micron dual stage to 1 micron. 2-Pentek 155263, RFFE20-BB Radial Flow Iron Removing Filter 3-Pentek RFCC-BB Carbon Filter you can add another Filter after the Carbon for media if you want. Not necessary but is an option or run 2 sediment filters in beginning of the system. -Various copper pipes and PVC pipes to build the system. I highly recommend a bypass valve and a way to shut off the water to your filters if you need to change them without losing water pressure to the house. -I experienced nearly 0 PSI drop thru the 3 filters and no noticeable change in flow rate.

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

Great Quality, Clean 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.

We have been using this filter for some time and I like the fact that my drinking water does not smell of chlorine.
