iSpringFP25BX6 High Capacity 20” x 4.5” Water Replacement Cartridges Fine Sediment Filters, 6 pieces / 5 microns, White, 6 Count

This is a carbon filter replacement for the iSpring Whole home filter system. I have had this installed at my home for about 4 years now and replace these filters yearly (I have city water). Overall I have been very happy with the quality of these filters. The entire home tastes chlorine free and I'm sure the overall quality of the water is improved but I've never had the water professionally tested. You can tell these are very high quality.Unscrewing the heavy canisters to replace the filter can be a little tough and require some strength. I would recommend lubricating the rubber seals with a food grade lubricant and not screwing them back on too tight. Also releasing the water pressure with the red buttons on the top is required.

have a 60 foot deep living well that I was going through filters like crazy with the whole house filter from Culligan. The well has a bunch of sediment so I was not surprised that it clogged a smaller single stage filter. The smaller filter would only get the sediment but the water would come out of the faucet with a brown tint and have a slight smell to it. I purchased the ISpring WGB32BM as well as an ISpring WSP-200SL Sediment Filter and with both of these combined the water to my cabin faucet was crystal clear, had zero sediment and had zero smell. Just to compare I set up an unopened purchased bottle of water next to a bottle of the water out of my faucet and the purchased bottle of water had visible sediment in the bottom of the bottle and the faucet water had no visible sediment at all. Fast forward two years after being installed (which was very simple) and I was changing out a well pump and had to change the location of the filtration system. I damaged the heads of the filtration system so I called ISpring and talked to Nick about purchasing the parts that I damaged. Nick was awesome and is shipping me a new one even though it was due to my fault. That is what you call great customer support.

FC25B cartridge filters are excellent on the post-filtered supply side of a water system.

When I installed this filter to reduce chlorine level of .4 ppb, it worked great.Free chlorine went to undetectable levels. We use about 200 gallons per day.After two months, chlorine was at .1 to .2 ppm level. I could have got a bad filter.Customer service was great and sent a replacement filter. I will report back later.

Very good price and fit right in.

We live in the Caribbean and use rain water for drinking. This filtration system is the best! Super easy to install and gives us clean drinking water. Highly recommend! Also, great customer service by Nick with any questions we had!

Fantastic customer service. Tech department is bar none.Will continue to use their products.

We have used a filtering system for over 8 years now. We live in a community with a water treatment system. It's not a complete filtering system and it also adds Chlorine. Yuk! In the beginning we used the Pentek FloPlus filters. They still go for $80 and up now on Amazon. Each time I replace a filter, I look for new alternatives. For instance, last time I found the  Geekpure 20-Inch Big Blue Carbon Block Water Filter . It was close to 1/3 the price I was paying. It came with 5-star reviews. Why not! I usually know that a new filter is needed when the pressure drops. It didn't drop this time, but I looked to replace it after 10 months - a long time! This time I found this iSpring FC25B. It too was close to 1/3 the price of the Pentek with the greatest capacity of any other filter and the best promise of Chlorine removal. The pressure was great. There was not even a hint of chlorine or anything else. Great tasting water. That's what I'm looking for. Now, we'll see how long it lasts and the pressure keeps up. That's the final test. Installation is easy. Turn of water to filter. I keep bypass closed and water is directed only to outdoor hose hookup (so I can clean housing). Open any faucet in house to release pressure. Remove old filter and clean housing and install new filter. Change and lubricate O-ring (with vegetable grade lubricant). Screw housing back in "hand tight." Then with the housing wrench tighten a bit more. Finally, open valve to send water through the filter. It's usually about a 10-15 minute job.

this filter works amazing for iron in your water.. easy to installresults are instant..no more rings in toilet bowl..

Après avoir creusé mon puits artésien, j'ai été déçu de cette odeur présente. Le sulfure d'hydrogène à noirci mon anode en magnésium du réservoir à eau chaude. J'ai corrigé cela en remplaçant l'anode de mon chauffe-eau Rheem par une anode Corro-Stop et ça fonctionné. L'eau froide restait un problème. Quand j'ai finalement trouvé ce filtre j'ai été très sceptique mais j'avais pas envi de payer une fortune pour éliminer le problème. J'ai acheté le système à trois filtres de iSpring. Le premier pour les sédiments, le 2e pour le sulfure d'hydrogène et autres pesticide et le 3e pour la filtration au charbon. En plus d'une bonne filtration je n'ai plus aucune odeur d'oeufs pourris. Plus que satisfait.Ajout au 18 décembre 2022. L'odeur d'oeufs pourris est réapparue après 6 mois. Ça dépend de chaque puits. Après remplacement, tout est revenu comme avant, sans aucune odeur. Donc 2 filtres FG25B-KS par année dans mon cas.

There is nothing to dislike in the product and product support. The Indian filters claim they are 5 microns. They are big cheats, only after using you will know. While using ISpring filters, use it with ISpring housing. You will see crystal clear water that you will wonder at the technology behind it, that is ISpring a hi tech company with a mindboggling range of products and they are also into IT but that is a sister concern
