iSpringRCC7AK, NSF Certified, 75 GPD, Alkaline 6-Stage Reverse Osmosis System, pH+ Remineralization RO Water Filter System Under Sink, Patented Top-Mounted Faucet Design for Easy Installation

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.

I work in the metal finishing industry and deal with $10k-50k RO/DI systems on a mfg level so I am very familiar with simple RO systems like this.TLDR: yes it’s a very good system. All consumer RO systems don’t differ from each other too much. But the nice part about this iSpring system is you get fantastic support in terms of parts and everything is user serviceable.Quality: very good. Parts are solid, and the water faucet has a very nice build quality. Does not scream cheap.Install: as easy as it gets. It comes with clear instructions and 90% of it is already pre assembled. All you do is drill a reject-water drain, connect the lines and install the faucet. No specialty tools are needed.The system replaces my old 4 stage RO system. After you install it, you will notice the clean water that comes out is very “dirty.” This is normal because you’ll need to be flushing out all the micro particulates inside these filters. This basically means you need to run about 5 gallons through it before it’s fully broken in.The spec’s on the iSpring system are decent for a consumer level RO system. In my tests, it makes Aprox 1gal of clean drinking water for every 1.5 gallons of reject water. This is expected if a $200 system. It would be a different story if it were an industrial level $20k system. So keep that in mind. The reject water will go down the drain (you can catch it in a container to water plants if you’re frugal with your water)Testing: my line of work allows me to have lab grade equipment to test water. By this I mean I can check for conductivity of the TDS and pH. I work with meaurments in terms of microsiemens (μS and mS). Generally, the lower the μS, the “cleaner” the water. However, μS does NOT indicate exactly what is in the water. Water was measured by my oakton CON110 (calibrated prior to testing)city water: 773μS @56F (not good, but SoCal has bad city water to begin with)1st gal sample: 4,050μS @59F (expected)2nd gal sample: 851μS @57F (getting better)Post 10gal sample: 45μS @77F (very good)Reject water: 1000-1100 μSPH boost: This system claims it will boost the PH due to its alkaline filter. Yes, it does it, but not by much and is pretty much worthless. the city water is around 7.2pH. My post water sample was at 7.7pH which is nowhere in “alkaline” territory. But it’s fine because alkaline water is a hoaxs anyways (coming from a bio chemical engineer, me). PH measured by my oakton PC450 meter (calibrated prior to testing with buffer 4/7/10 @77F).Overall, it’s a very good system and does what it’s suppose to: remove TDS from dirty city water and create clean good tasting drinking water. It took my 773uS city water (SoCal) down to 45uS, which is better than I expected.Keep in mind these numbers will change over time as your filters/RO membrane get dirty. If you live in SoCal where your city water is 700-900uS, you’ll have to change them MUCH more frequently than if you lived in WA where your city water is 75-150uS (I use to live there).

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.

On the recommendation of our contractor, we purchased this system for our condo at South Padre Island, Texas. System was installed by our contractor and worked great; you could really tell a difference in the clarity and taste of the water. Contractor also ran a separate line to our refrigerator so that we could use filtered water in our ice maker.Since we don't use the condo everyday, the filters lasted 4+ years until I changed them in January, 2024. Used the online instructions and videos. While it took longer than I originally anticipated, I was able to change out all filters with no leaks or other problems.Early this year we noticed that the faucet had developed a slow drip. I contacted iSpring and talked to John about this issue. Despite being out of the warranty period, John said that he would send us a new faucet at no charge!We have loved this system and the customer service at iSpring has been fantastic. Thank you John for you great service!
