Pentair Pentek RFFE20-BB Big Blue Water Filter, 20-Inch, Whole House Radial Flow Iron Reduction Replacement Cartridge, 20" x 4.5", Pack of 4

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.

Does an outstanding job of removing iron. My shallow well system used to have a reddish/orange tint to it, and white clothing going through the washer would be ruined. I installed a sediment filter, followed by this iron filter, and finally a UV sterilizer in my water system this year. The water discoloration vanished, with just a hint of a faint yellow color left. This does no damage to clothes, and the shower and toilet are now free of stains.There is no odor to the water, and I can not comment on taste because we don't use the water for drinking because there is a crystal clear spring near our house. However, this filter has solved the rust problem for us. After one month of use, my gauges show no pressure drop, so I am expecting long life from this unit. TIP: Don't get a smaller filter. Yes, it will be cheaper, but then you WILL get a pressure drop much more quickly.

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.

I needed my filters changed regularly since I have a high iron content in my well water. The plumber suggested I change my filters more often. These are the prefect fit and now I have a lower bill and can change the filters myself without the cost for a plumber's visit.

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???

This iron filter fits my needs, Our water well is shallow under 50 feet and this filter works great.

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

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.

Removes all the iron and manganese I have in the well water, it is a space saver, easy to replace (yearly in my case) however the price has skyrocketed in the past years. I consider now a more cost effective solution.

I installed a new well water filtration system and use this product in conjunction with a 1000 micron washable sediment pre-filter and two paper filters to reduce iron oxide and sand that enters the plumbing system (thanks to a local water expert in my area). I have a 4 chamber system setup. First is the 1000 micron pre-filter and mine needs to be cleaned about every 14 days. It is a simple task and takes 5 minutes to do. (In my case I have sand and heavy iron content). Then a paper filter, then the iron filter and finally another paper filter.I have noticed a remarkable difference in my water. Specifically in all my water using fixtures and appliances.I have been using this setup for about 8 months now and feel the carbon filter will last at least a year if not longer. I also have found that the first paper filter needs to be changed after about 8 months. I then rotate the second paper filter to the first position as it has very little staining. Then add the new paper filter into the last position.Why I reviewed this product in depth is because after 12 years of fighting a losing battle and thinking there was no answer, I have found that this setup has worked beautifully. I highly suggest to talk to water experts in your area as they are probably tuned in to what you may be experiencing.Good luck!
