Great product, came in safe and sterile packaging which is what you like to see when ordering a filter for drinking water. Does the trick for removing the little bit of iron I have in my water. Definitely recommend

We use these filters to help with our well water to decrease minerals. Really seems to help for drinking and decreasing deposits on our fixtures around the house.

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.

This filter has changed my life! We live in an area with crappy high iron water. I sometimes have difficulty washing whites because our water leaves iron stains on them. I had a different filter in, suggested by my "water guy," but it just didn't seem to do the job. I installed this Pentek 155263, RFFE20-BB Radial Flow Iron Reduction Cartridge and within MINUTES my water was clearer and cleaner! I can wash whites without spots, and the handmade soaps we use not longer leave sticky soap scum on the tubs and sinks. I have FINALLY gotten rid of the yellow stains left on the fiberglass tub. When I fill up the tub the water no longer has a yellow tinge. It's a bit expensive, but then so are clothes. This filter is the absolute best for my high iron well water!

Item is just what we expected it to be, and it seems to work well in our system. We have bought a couple of these.

My iron is all undissolved iron at 3ppm or more. By adding just a 1 micron sediment filter it drops to around 0.5ppm (1 ppm at most). I initially had a similar iSpring 20x4.5" Iron filter (similar price too). It lasted maybe 3 weeks 1000 gallons with at most being hit with 1 ppm of iron. I had both 1 micro filter and a carbon filter before it. It doesn't reduce iron at all after 3 weeks. I decided to give it one more shot and try Pentair Iron filter. I probably would have bought the Pentair first had I known it existed. I have had good experience with Pentair. I use Pentair components on my pool. Any way I have again a 1 Micron Filter before this Pentair (also 20x4.5"). But after some research watching videos I put the carbon filter after this iron filter. Some documents say this filter oxidizes the iron and then a post filter needs to pick it up. I'm not sure about that and if that applies to undissolved iron. Any way my Carbon filter is a 0.5 Micron and also made by Pentair. It cost almost as much as the iron filter. The water is perfect now. Pentair claims 80,000 gallons at 1ppm. Should last 2 years. We'll see but it's looking much better than the iSpring filters I installed first. I've been running for 6 weeks and 2000 gallons. I also top off the kitchen sink drinking spigot with a WaterDrop filter that does 0.01 Micron. This is also a GREAT filter and not expensive and should last 2 years (19,000 gallons). Even when the iSpring was falling to get the iron out the water out of the Waterdrop was still perfect.

Promised up to 3 ppm iron removal. Test strips showed a bit above 0.3 ppm before putting in this filter. Afterwards below 0.3 perhaps at 0.

Like others, I have the iSpring system. The filters from iSpring should last a year. They never really did a great job at removing iron. They were better than nothing, but I was still getting iron stains in my toilets. I had to use iron out every 2 weeks to remove the stains. I decided to give Pentair a try since their pool products are good. Well I put this filter (along with carbon and sediment) in my iSpring housings on Dec. 30th. It's now January 23 and no visible iron stains in the toilet. Definitely worth the slightly higher price and they fit the iSpring blue 20" housings with no issue.

As someone who has struggled with high iron content in our well water for years, leading to frustrating metallic tastes, unpleasant odors, and stubborn orange staining on fixtures and laundry, finding an effective solution was paramount. After researching various options, I decided to try the Pentek RFFE20-BB Iron Reduction Filter, 20x4.5-Inch, and I am absolutely thrilled with the results – it deserves every one of its five stars! From the moment we installed this filter, the difference was immediate and dramatic. The 20x4.5-inch size was a perfect fit for our whole-house filter system, making the replacement process straightforward. Within hours of flushing the lines, our water was noticeably clearer, tasted fresh and pure, and the metallic tang was completely gone. What truly impresses me is its iron reduction capability. We no longer see any new orange stains forming in our sinks, toilets, or washing machine. Our white laundry stays brilliantly white, and even bathing is a more pleasant experience without the lingering iron smell. This filter has genuinely protected our plumbing and appliances from the corrosive and staining effects of iron, which will undoubtedly save us money and hassle in the long run. The build quality feels robust, suggesting good longevity and performance between changes. It consistently delivers clean, great-tasting water throughout our entire home. If you're battling iron issues in your water supply, do yourself a favor and invest in the Pentek RFFE20-BB. It's a game-changer and has significantly improved our daily lives. Highly, highly recommended!

A bit pricey but definitely reduces iron - we use it in our mail supply and after the pressure pump - roughly lasts about 2 months for a family of 3.

Perfekt, genau das was ich brauchte. Kann diesen Artikel nur weiter empfehlen.

Such a great value for your money. We usually buy it from the Water Store in town and one alone costs $400. They work perfect for our water filtration system. LOVE a great deal on amazon!

Too expensive whether from Amazon or elsewhere. Up 45% fgrom April 2024 so gouging is what I would call it!
