Pentair Pentek RFFE20-BB Big Blue Water Filter, 20-Inch, Whole House Radial Flow Iron Reduction Replacement Cartridge, 20" x 4.5", White

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

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.

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.

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.

It should be noted that reviews about this being a 10 GPM filter must refer to some earlier spec of this filter; mine arrived in Pentek packaging (so it appears to be the real deal), but it plainy states "6 gpm" on the label. I placed it in service anyway and over the past week it appears to have dropped the dissolved iron levels in our water considerably. No formal test beyond observation of previous hot spots of iron buildup (still clean !); 6gpm is lower than the 10gpm minimum I was hoping for after seeing the other review, but the drop from 8gpm (my previous rate-restricted by a water softener) to 6 has been minimally noticeable with regular use. I just haven't had it long enough to see if it justifies a glowing review.

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!

I buy these about every six months and they do help to mitigate iron; I use it in front of my brine/resin filter. I was about to order another and saw the price has jumped to $100.66 from $76.03 back in December 2017, a 33% increase! I don't understand Amazon's pricing policies...prices change sometimes right before your eyes. It would be helpful to have two ways to rate purchases, by the product and how it performs along with how Amazon handles sales, returns, pricing etc. This filter is a five-star item but I lowered the overall rating because of the extreme price change. It forced me to look around and I found the same product at witerfilters dot net for about the same as I was paying in December. If you look around you'll find a coupon code that will reduce the price even more, as will a subscription. Again, the filter is fine, but Amazon???

I use a sediment filter (DGD-2501) in combination with this Iron Filter (RFFE10-BB) and carbon block filter (EP-BB) in my house water system. Best thing I've done. These just plain work. Change the filters on a yearly basis since it is just two of us in the household...no more brown (iron) deposits/stains !!

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.

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!
