iSpring FC15 5 Micron 10" Replacement CTO Carbon Block Water Filter Cartridge for Under Sink Reverse Osmosis RO Filtration System,10" x 2-1/2", White

iSpring's countertop water drinking filter is hands down one of the best purchases I’ve ever made. The carbon filter is huge, sturdy, and easy to set up. Compared to those flimsy pitchers that break after a month of use, this filter is a game changer. It saves me money in the long run and provides crystal clear water that gives me peace of mind.The best part? The water is filtered instantly. Thanks to the pressure system, there’s no waiting around for your water to drip through like with other systems. The spout is convenient, and the sink attachment lets you easily toggle between regular and filtered water. I’ve been using iSpring’s five-micron filter for years, and it lasts months, handling my water’s impurities with ease.I’ve moved twice since purchasing it, and I always take my iSpring filter with me. No matter where I live, this filter makes the water taste and feel cleaner. One time when I changed the filter, I was shocked to see all the gunk it had trapped—it was gross but satisfying to know the filter is working better than expected.On top of having an incredible product, iSpring’s customer service is unmatched. They helped me with an issue and went above and beyond to make sure everything was resolved quickly. I’ll always stand by this company and would recommend their filters to anyone. I’m even saving up for their reverse osmosis system because I know their products are built to last. If you’re looking for a high-quality water filter that you can rely on, iSpring is the way to go.

Really nice product at an unmatchable price. Easy to install. Mine came with a missing adapter for the faucet, but I was able to sort it out with amazon, and its really the best bang for your buck if your health conscious or have particularly hard water like me. Will be purchasing a filter after the suggested 6 months. Great product.

Works perfectly and super easy to install. The instructions didn’t help a lot but I was able to troubleshoot on my own and I’m not handy at all.Such a great product for a great price!

A good low cost countertop filtration system that provides good tasting tap water. The system is relatively easy to assemble, but the directions need work. For one, make the print larger so a magnifying glass is not required to read the instructions. Secondly, provide accurate information for the installation of the filter. I read two different filter installation procedures, the one provided with the system and another from the company's website and both were different. The Installation Manual procedure instructs you to "*PLACE THE FILTER WITH THE BLACK CARBON SIDE POINTING DOWN. However, there is no black carbon side. The Users Manual procedures instruct you to "PLACE THE GAC FILTER WITH THE ARROW POINTING UP" and there is no arrow on the filter. I also purchased a replacement filter and I didn't see a black carbon side or arrows on that filter. Since that filter can only be installed one of two ways, my personal opinion is that it doesn't matter how it is installed.

This is an excellent filter system. I've had others over the years but this one is the best. Pure water! I mean tasteless. So refreshing. If you can taste water then the filter is not good. This system is great! I highly recommend it. Easy to install, with in 15 to 20 mins. Max. Follow directions carefully! Happy camper!

Why did you pick this product vs others?:This is a good product when it arrives in good order unfortunately it was not packed safely.

I've had my unit for quite a number of years and haven't had any problems with it. Just keep the filters changed and clean in between filter changes. Best not to let it get a lot of sunlight as it could grow algae. I didn't realize when I bought it that it was going to have to sit so close to the sink but that's my bad for not paying better attention to the product description. I still worked out just fine because the size makes it not invasive. It was easy enough to install and has held up very well.

Must preface this to add that I have been using various countertop filters for more than ten years and I know how they work.That said, this unit arrived adequately packaged but something seemed off to me and at first I thought it was a return/refurb and maybe missing some components. I contacted customer support and they were wonderful and sent me another unit. In the meantime, I had installed the first one using a part from an older other brand and it did seem to be going okay but they already had another unit on the way! Just want to say that Don and Brian are very much into the customer service aspect and quite responsive.I do enjoy the transparent casing, this is the first time I have had a clear one (actually it is blue). It does not go with my kitchen decor but I figure I can always crochet a cozy for it if I don't want guests to be offended by the color clash or seeing (when it does) get icky from catching stuff. For now, it is nice to see the water going through it. Also, this is significantly more substantial than other brands I have owned. It is a good sturdy weight and not easily knocked over or flimsy.To people with leaking problems, a) DO NOT use the wrench to tighten the filter on install. Just like your truck car filter, it will squish the gasket out of place and have the opposite effect. The wrench is for taking it off. b) leaking at the faucet - be sure you cleaned the threads in your faucet spout and have the correct washer in there. I have never had a faucet adapter leak in ten years. c) if you have housing leaks it is the big o-ring on the canister. This is why I got turned off of this type for awhile- they are fine until you change the filter but have the same big o-ring on the housing. They always lieak by two or three cartridge changes. Use a vendor that has replacement o-rings available. You can thank me later.
