iSpring F9K NSF Certified 1-Year Reverse Osmosis Water Filter, Alkaline Remineralization Filters for 6-Stage RO Systems, Without RO Membrane

The iSpring RO system has been a great addition to our home. Installation was surprisingly easy, took us close to 4 hours. The water tastes clean and fresh with no chemical aftertaste. The system feels well-made and runs quietly. One issue we faced was the RO faucet kept leaking but that was quickly solved by their customer service rep Julius who sent a new spare part quickly and for free. We have no other problems for now. Overall, it’s a reliable and affordable solution for anyone looking to improve their drinking water quality.

This system replaced a 14-years old RO system from another manufacturer and I am very happy with this decision. It was nicely packaged, components are solid, and even extra parts are included. Installation of RCC7-BN was pretty straightforward, takes me about two hours, and both manual and YouTube video is helpful. Production speed and capacity are impressive too, and we have great-tasting water next day. For comparison, our city water has a TDS 130, and RO water - 4. Also, by feeding it to our fridge (with separate kit from iSpring) we got great quality ice without any smell and eliminated old ice maker filter.Having some issues with extended warranty registration online, I contacted customer service, and Nick helped me right away. I would definitely recommend this great product (you just can't go wrong with more than 16K overwhelmingly positive reviews).

We had been living with well water for a couple of years and were very unthrilled with everything about it. It was tolerable with a filter going through the refrigerator and on the shower head, but not great. Then something went very wrong and I still don't know what. My white towels came out yellow after a wash telling me that what I had already felt was right something was wrong with the water. So finally the landlord put a filter on the main pump, which was shocking to me to discover there hadn't been one in the first place, and the towels stopped being yellow. But the water still felt and tasted gross. I was intestinally ill and didn't know why. And then my hair was ruined. The hair strands became narrowed to almost nothing. I had to cut it very short as it just looked like spider silk. We then moved and we're back on city water and it has started the LONG process to recovery. I'm giving this ridiculous detail to let you know how fully skeptical and freaked out I was about water in general. When we first tasted the water in our new place which is on city water (reports say it's some of the best in the country) we thought something was wrong with it because it tasted so different. It was fine, WE were tainted having been poisoned for 2 years. So we filtered it through the refrigerator and it wasn't bad. Then the fridge died. So I combed through different water filtration systems and tried one which arrived broken. Didn't find that out until I had been working on the install for an hour! BE SURE TO INSPECT ANY PRODUCT BEFORE BEGINNING AN INSTALL. I'm going to get a pillow embroidered with that... Anyway! Then a reverse osmosis system was recommended to me and our lives were changed forever. I went through many of the RO systems on Amazon & eBay before settling on imprint. Their video was informative and made me feel that I could install it easily. I was fortunate that a hole was already drilled in the counter for a soap dispenser which I wasn't using. So the only issues with installation and these could have been my fault were not being sure if the little blue clips could go in either way (they can!) and really making sure that the tube had been FIRMLY pushed in. They say to, but I was far too worried I would hurt the tube. Don't be. That suckered is sturdy! There are 2 other issues that I would say determine whether you can easily do this yourself. Physically, I will say I'm not in athletic shape. I have knee, back, and neck issues and vertigo when lying down. (I'm a wreck I know!) This made getting under the sink several times and lying on my back to tighten the faucet challenging. Not undoable, but not the easiest. The clips and all the hoses are explained and color coded very well. That part is very easy. But this is not a light unit. It's heavy which is great in that I really felt it was substantive! But, a little tough when I had to pick it up and put it on the counter several times. Did I mention my bad back as well? Anyway, it was all ready to go when we read the final step. Drill a hole into the waste pipe. Hmmm. I have a drill, but drill into a pipe? In a rental? And while they describe it and it seemed simple enough, the picture didn't look like my pipes. I was lucky enough that the guy who recommended an RO system in the first place was happy to take five minutes out of his day and come over and drill the hole. It was nothing to him, super easy. He actually put the hole into the garbage disposal waste pipe, BTW. SO! As far as installation: depends on your comfort level with drilling a hole into a pipe and physical ability for awkward spaces and kneeling, twisting, etc. I did it though! And that means most of you can too. But you might also want to get all the tunes connected and then hire someone to install it the rest of the way. Don't pay them for connecting those tunes, you can do it! And now the conclusion: How does the water taste? Well, there is just no comparison. Screw Brita and Pur and those 4th rate filters that aren't doing anything worthwhile and you have to constantly refill a horrible pitcher over and over. This water tastes like you think water will taste! Clear, clean, no aftertaste. Just... water! I wish there was a way to be able to bathe in it! And it's that good at room temperature! For those who chill their water just because it tastes better that way, you don't have to! We also were having to buy bagged ice from the grocery store because the fridge that died was also our icemaker and the new fridge didn't have one. That ice is gross. Seriously. You know that smell from the plastic bag that it's in and how it transfers to ice? Bleah! But, I didn't want to make ice cubes with trays as it's a bottom freezer so I would spill the water all the time! What to do... A friend living in an RV told me to buy an icemaker. I was skeptical because I thought it wouldn't work that well, but without giving that a review here, it does work! Bye bye bagged ice!! So now we have the greatest drinking water we've ever had coming right out of a little faucet in the kitchen sink and we can put it into our tiny ice maker to make the best tasting ice we've ever had! And let me tell you, if you think good ice doesn't matter, you are just crazy. What's the point of putting your favorite beverage over something that will make it taste bad? I mean forget any diet soda, that tastes so bad it doesn't matter, but a $65 bottle of Redbreast Irish whiskey? Mmmmmmm.

I recently installed the iSpring RCC7AK-BLK 6-Stage Reverse Osmosis System, and overall, I’m very happy with the product. The installation process was relatively easy, especially thanks to the generous length of tubing included. This allowed me to assemble the unit and make all the necessary connections outside of the cabinet first. Once I confirmed everything was working properly, I was able to neatly move the fully connected system under the sink - a big time and hassle saver.My old system that I was replacing had much shorter tubing and it was quite a pain to change the filters and to remove the system.I did run into an issue with a leaky RO faucet a couple of weeks after installation, but iSpring’s customer service really impressed me. I reached out and was quickly helped by Nick, who arranged for a replacement faucet that arrived just a few days later. The quick and helpful support made a great difference and gave me extra confidence in the brand.The system works well and the water tastes good.The black faucet design is also a nice touch and complements our kitchen nicely.Highly recommend this unit for anyone looking to install/replace a reverse osmosis system with one that was relatively easy to install and had great customer support when it was needed.
