iSpring RCC1UP-AK, 100 GPD 7-Stage Reverse Osmosis Under Sink Water Filtration System with Boost Pump, Alkaline Remineralization and UV Filter, Patented Top-Mounted Faucet Design for Easy Installation

I couldn’t be happier with my iSpring RCC1UP-AK Reverse Osmosis Water Filtration System! As someone who’s been concerned about the quality of tap water, especially the fluoride content, this system has completely changed my peace of mind. I’ve always been cautious about the water we drink and cook with, and now I feel so much safer. Setting it up was pretty straightforward. The instructions were clear, and the system fit under my sink without any issues. After installation, I tested the water with a TDS (Total Dissolved Solids) tester, and I was amazed to see that the water was at a perfect 43 ppm – that’s incredibly low and means the filtration is working exactly as promised. For reference, my tap water had a TDS reading 155, so this system really makes a huge difference. The taste of the water is noticeably better. It's crisp, clean, and refreshing – perfect for drinking, cooking, and making coffee or tea. I feel so much more confident using it in all aspects of my daily routine. Overall, I highly recommend the iSpring RCC1UP-AK system to anyone who’s looking for a reliable, high-quality reverse osmosis filtration system. It’s a fantastic investment in both health and convenience. If you’re serious about water quality, this system will not disappoint!

Updated Review Below after dealing with customer service to fix the system. Edits: The system has been five stars all along, however, there was a period when I had given it 4 stars due to the difficulty in obtaining replacement filter packs. I was told by customer service this was due to the pandemic and supply shortages for the UV bulbs. In the past 6 to 12 months I have not seen any filter supply outages. I am re-instating five stars. I own a residence in the country and I am on well water. I drink a lot of water. For years I had a water cooler and had 5 gallon bottles of water delivered. So I am very used to the taste of that water. I decided, as a way to save money, I would get a RO water filtration system installed under the sink of my house. After researching for a fair amount of time I ended up purchasing the 7 stage 100 GPD iSpring RO system in late 2019. I watched the installation video and read the directions. It was pretty simple to set up. It does take some time to get it completely installed. I took my time and I am happy with the final installation. I feel that the video and the written instructions are very good to help get the system installed. After the installation the instructions state to fill the tank and then empty it. I followed those directions. At first I wasn't a big fan of the taste differences. I can tell the difference between a lot of the off-the-shelf bottled water, so I figured this would take a bit of time to get accustomed to the taste of the local well-water and the difference in how the final product was filtered. As time went on I started to enjoy the taste of the water. One of the big reasons I got this system was the protection from possible pollutants that could get into the water. I have the well system tested, but that only tells me the water is okay at that point-in-time. I have no idea if it is still good a month later. This system gives me peace in that regard. I am satisfied with the system. I am happy that I got it and I am no longer buying bottles of water. -----UPDATE 012322----- In December 2021 I started to have an issue with one of the lines. I made a short video and E-mailed it to customer support. I worked with one of their customer support agency, Francis. We exchanged E-mailed back and forth. The first diagnosis was a faulty solenoid. Based on where I could visibly see the problem, I felt that he was correct and was excited to receive the replacement part, which was covered under the warranty. But after I replaced it, the problem still was happening. Francis then said he would send out a whole new head unit to ensure the problem was fixed in a timely manner. I had just changed the filters approximately one month prior. The filters are good from anywhere between 6 to 12 months. So I wasn’t too excited about having to put in new filters. Francis also hooked me up with filters so my new ones didn’t go to waste. The new head fixed the problem. It fixed the problem and I am up and running. As far as customer service goes, I am happy. I didn't get a run around. I got replies from Francis within the next 24-hours. He did what was needed to make sure my system works.

Did a lot of research and reading and ended up going with the iSpring RCC1UP-AK. I like that it is a true 7 stage (meaning 7 actual vessels the water passes through). And that it has a large UV vessel (powered) along with a powered pump (very quiet) for added pressure when filling. The instruction video was good and straight forward. I didn't have any questions during the install that weren't covered in the video. For the drain line I ended up using a garbage disposal adapter (https://www.amazon.com/dp/B08YP9VKHZ?ref=ppx_yo2ov_dt_b_fed_asin_title) to avoid drilling into the waste piping. I'm also impressed that iSpring provides a leak/flood shut off valve. Even though it is mechanical with a disc that needs to be replaced once it gets wet - it's a great adder. I've only had it installed for about a week and so far, it is operating fine - no problems. I will eventually do a full water test report to verify clean water. I did, per another reviewer's suggestion, go ahead and add a 3 way valve to the last pre filter output. That way when I need to replace the prefilters and do the initial flush I can just flip the 3-way valve (https://www.amazon.com/dp/B0F7HQMH7L?ref=ppx_yo2ov_dt_b_fed_asin_title) to the hose that I can run to the drain. This avoids having to disconnect the red tubing and connect to the drain as described in the install video each time I replace the prefilters. Also, I have considered adding an additional faucet for pure RO water before the Alkaline adder. That way I'd have a choice between pure RO water and clean RO water with minerals added back in. I did put an electronic water leak alarm (https://www.amazon.com/dp/B0CKYTP2DM?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) and a rubber water catch mat (https://www.amazon.com/dp/B0D6YWKXVC?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) in with the RO system as a just in case. And thanks to Julius for securing my 3-year extended warranty.

This review is for the following: iSpring RCC1UP-AK 100 GPD 7-Stage Reverse Osmosis Under Sink Water Filtration System with Boost Pump, Alkaline Remineralization, UV Filter, and Top-Mounted Faucet; purchased 8 Jul 25, installed 17 Jul 25. iSpring WGB32B-KDS 3-Stage Whole House Water Filter with a 1st Stage Anti-Scale Water Filter, 2nd Stage GAC+KDF Heavy Metal Reducing Filter, and a 3rd stage Carbon Block Filter; purchased 20 Jul 25, installed 27 Jul 25. iSpring WSPSL-ARJ-BP Spin Down Sediment Water Filter with Siliphos and Touch-Screen Auto Flushing; purchased 20 Jul 25, installed 27 Jul 25. I wanted to install a drinking water filtration system for several years but never had the time to do it. Now that I’m retired, I decided it was time to finally get it done. Our city water source in Alaska meets “approved” levels for water quality, but always has a sulfur smell, and scaling is also a problem. To add to our concerns, we often get sediment when we have earthquakes near our area. I spent a great deal of time reviewing various filtration systems on the internet and Amazon to find the best fit for my needs. Though there are many good systems out there, I chose iSpring because they offered the best options and had the best reviews for filtration systems and customer support. I first purchased and installed the RCC1UP-AK 7-Stage RO/UV drinking water filtration system thinking that was all I wanted. I mounted it in my basement crawl space underneath the refrigerator because of the ease of running wiring for an electrical GFCI receptacle from my garage circuit breaker panel to power the booster pump and UV filter, and because of the way my PEX piping is routed. I’m very qualified to perform this type of work but wouldn’t recommend someone doing the same if not knowledgeable and qualified, that includes splicing in valves and connectors for PEX tubing and installing the filtration system, not to mention any electrical work. It took me two days to get everything installed from running a feed line for the drinking water sink faucet, creating a filter bypass line, splicing into the refrigerator ice maker/drinking water line, running an electrical circuit, and mounting and activating the new RO/UV filtration system. To say my wife and I are pleased with the quality of the drinking water we are getting from our new filtration system would be an understatement. Whether we get the drinking water chilled from the refrigerator faucet or from the new sink faucet, the RO/UV filtered water tastes outstandingly fresh and pure. And the bonus of having the sink drinking faucet is we can now wash our fruits and vegetables in purified water! Should anyone want to know, the TDS readings for our unfiltered water supply runs around 250ppm, but coming from the RO/UV filter, it drops to 12ppm. Because of how well the RO/UV filtration system works, and because we still have the problem of the sulfur smell, scaling, and earthquake caused sediment coming out of the rest of the house faucets, I decided to purchase and install a Whole House Filtration System. Again, I went with iSpring for the same reasons I installed the RO/UV Filtration System. However, I decided to go with their ultimate filters for the 3 stage Filtration System and the Spin-Down Sediment Filter. Again, I installed the system in the crawl space, but next to the water supply entrance and extended the electrical circuit for a second GFCI receptacle to power the Sediment Filter Auto Flush. This time, it took me 4 days to complete the job because I took advantage of the incoming water shutoff to splice in SharkBite Max cold/hot water valves to every feeder line in the house for individual isolation. What a difference having a Whole House Filtration System has made to the quality of our water. It has been just over a week since it went on-line, and the results have been absolutely incredible. We no longer have the sulfur smell, and scaling is completely gone. We haven’t had any local earthquakes yet, but I’m certain we won’t have a sediment problem either. I can also comment on iSpring’s customer service. I took advantage of their free 3-year warranty extension by registering the products on their website. I’m not going to say it was easy to input the information on their support page because it doesn’t seem to function very well. It took me at least 3 tries for each of the Filtration Systems because the website kept giving errors and locking up, but perseverance prevailed, and I was finally able to register all three systems. It didn’t take but a day to hear back from Sean and Nick respectively to let me know that my 3-year warranties have been activated. Though I didn’t speak to them directly, I’m certain I would be very happy talking with them to help me with any issues I might have. Other reviews mention how helpful customer service personnel are or have been and I can believe it. Bottom line, I highly recommend iSpring Filtration Systems for your drinking and/or whole house filter needs. You won’t be sorry! And check out the attached photos to get an idea of my installation.

Exceptional Quality and Service: A 4-Month Review of the iSpring RCC1UP-AK-BLK After four months of use, I am incredibly satisfied with my investment in the iSpring RCC1UP-AK-BLK 7-Stage Reverse Osmosis System. I chose this model to ensure safer, better-tasting water for my home while eliminating microplastics from bottled water. Value & Investment This system is a great money-saver. Based on my calculations, the unit will pay for itself in less than 11 months, meaning I only have eight months left until it has completely cleared its own cost. Customer Service & Delivery Before purchasing, I contacted iSpring directly with several questions. A representative named Francis was truly kind and helpful, guiding me toward the right unit for my needs. I ordered via Amazon on December 31st, and it arrived in perfect condition by January 3rd. The packaging was excellent, with every component individually protected. Installation & Build Quality The materials are high quality, and the instructions are clear and easy to follow. Straight forward installation with diagrams, mayor components ensembled. Because I am currently renting, I installed the system in the laundry room rather than under the kitchen sink. Following the recommended steps led to a perfect installation with zero leaks or issues. Pro-Tip: Monitoring Performance I chose to add pressure gauges to monitor three critical points: incoming street pressure, post-prefilter pressure, and the pump pressure entering the membrane. Here is what I have learned for those looking to optimize their system: • Optimal Pressure: The system performs best between 40–80 PSI (60 PSI is ideal). • Prefilter Health: A 2–3 PSI drop between the incoming water and the post-prefilter gauge is normal. A larger drop indicates it is time to change the filters. • Recommended Changes to Time Schedule Changes: o Keep this in mind the time between changes will be directly affected by conditions of the fed water. Your city or raw water will have water hardness that will impact the prefilter life span. If you do not pay attention will also affect the RO Membrane o Note: Water Hardness; concentration of Calcium and Magnesium. Must be a major concern if your water came from a well, instead of the city water. Will need specialized test or Professional Private lab test to determine results. o TDS or Total Dissolved Solids; All dissolved Organic and Inorganic Substances. This is an easier way to evaluate (and safer if is city water) and know your TDS Number, e.g., salts, metals, minerals, including Calcium and Magnesium dissolved in your water. • Note: Always consult, there is a possibility that any modification(s), alteration(s) may void seller warranty. • Scientific Monitoring (Rejection Rate): You can use a TDS meter to calculate the Rejection Rate: o Formula: [(Feed TDS – Permeate TDS) / Feed TDS] x 100 o You will need to buy a TDS Meter, to measure PPM (parts per million)  Notes:  If you are interested in a System with Remineralization (to add back essentials minerals, calcium, magnesium sodium, and potassium, to enhance water quality and taste) I strongly suggest getting a Meter that also reads Ph; helps you visualize the water alkalinity level (the higher more alkaline).  If the meter can read Conductivity, it can give you a notion of the Water Hardness and TDS (the lower the, lower the amount of WH and TDS).  Values of TDS on a RO System with Alkalinization stage are always higher than a None Alkalinization stage one. o A rate of 95–99% is excellent. o If it drops below 95%, it is time for re-order, 94-90% replace. o 90-below, you should not wait for this values. You may want to run on the safe side; remember you want to extend RO Membrane life. Final Verdict: Pros: I highly recommend iSpring Water Systems LLC. Their support is top-notch, and the product quality is evident. I choose the one with pump because it makes it more efficient in terms of less wastewater (known as; rejected, concentrated or brine), and faster & great-taste water than the one without pump. Need to add that the UV filtration is a plus for killing living things (not our actual case, but later; we may have one with water well) adding more safe water. I never measure the exact time to produce a full RO tank (from empty to full), but as an approximation is less than one hour Straight forward installation with diagrams, mayor components ensembled. Everything came extremely well packaged in a single big box. The first of the three prefilters is transparent, giving you a chance to see the condition. The mechanism to stop the water input (to the system) it is great idea to helps prevent water damage in case of an accident. Cons: Be aware that on this configuration you will be required to have an electric receptacle to power the Pump and the UV Ultra-Violet Sterilizer. In a power failure you cannot produce water without modification. Closing Statement If you are not sure which model fits your home, their support team is easy to reach by phone or email. Great product and great service—special thanks to Francis for the help!

I want to start by saying kudos to iSpring for excellent documentation. This product could be considered somewhat difficult to install if it wasn’t for the detailed step by step directions. I also recommend the youtube video. Why did we purchase this product? Fish were dying. LOL. Yes that correct our aquarium fish were dying and we wanted to know why. In the process of troubleshooting the aquarium issue, we found out the KH Hardness (Carbonate hardness) of our well water was off the chart. Over 214 ppm. My wife researched the effects of consuming water with high Carbonate hardness levels. You don’t want to know. Or perhaps you do. OK so the fish were acting like the canary in the coal mine. So yes we purchased a $350 filter so we can get clean water for our fish. Just kidding. It was obvious after my wife’s research that we needed to do something for our health. In fact we we're concerned that we consumed this water for years without this filter. Why we chose to purchase the pump option In my research, I learned that the model that included a pump (for use with low water pressure areas) would create less wastewater during the filter process. This was a concern because we have a septic system so we went for the extra $40. It turns out that with or without the pump the amount of wastewater produced is equal to about 1 – 2 toilette flushes but with the pump, it’s less. How much less? Good question. Sorry, I don’t know the answer. The Install Because we purchased the model with the pump and UV light I needed to run electric into the cabinet (next to the sink). This was 50% of my install time. It was n’t too bad. I have an understanding of electric but if you don’t you will need to hire an electrician. Read the install manual and watch the youtube video. When you open the box it is somewhat intimidating. Lots of hoses. Thanks to iSpring they are all a different color. The install is indeed quite easy as long as you follow the steps. Because we still use the cabinet for pots and pans, I did decide to build a removable wood box around the filter to protect. My fear was a hose would get pulled out while grabbing a pan. To be honest I’m worrying for no good reason. The quick connect feature of the hoses are rock solid. The water WOW. OK now we can reap the reward. The water does indeed taste better. What should water taste like? Well not like it has been for all the years without a filter. We also noticed a difference with the coffee. We purchased a connect kit for the refrigerator ($20 from iSpring) so the same filtered water is used for ice. (We didn’t know that ice could be so clear) Not to mention we will now save $$$ because we no longer need the GE refrigerator water filter. Pros I think I mentioned most of the pros above. After the cost of the filter, I can expect to pay less than $100 per a year for maintenance. I list this as a pro because it seems reasonable. Several filters are included in a 12-month kit. Install was on the easy side. Quality materials used for the product. Can fill the 3.2-gallon tank in just about 40 minutes. Cons A lot of hoses. OK OK they are all needed but still a lot of hoses. One con is with RO filters in general. You can run out of the filtered water. As mentioned above, the 3.2-gallon tank can be filled in about 40 minutes but the fact that you can run out is a con. Perhaps a 5-gallon tank would be better. I guess I could upgrade the tank if this is a big issue. Bottom line is I would recommend this product. It’s well worth the money and now my fish are happy. Oh I should mention that the Carbonate hardness level of the filtered water is zero. I thought the test kit was broken. I expected the level to be lower but not zero.

PRODUCT: I tried a few other R/O systems and this one is as good as it gets for residential. I'll explain. If you really want high quality , safe and delicious water to consume then you have to have the 7 stage system at a minimum. An R/o system is essential because not only will your water be pure but when combined with the UV light you are now essentially addressing everything that can be wrong with water. Your handling heavy metals, viruses and bacteria. We all can buy a carbon filter and such but they do not protect you against the real issues with "bad" water. You need the whole system to have the highest quality water possible. I will get to one other VERY important feature that this system has over the others but let me make one more point. This system has the common industry filters, then combines the R/O and UV to address the very small micron size particles and of course they have filters that add back essential minerals because pure unmineralized water is actually bad for you. Pure unmineralized water wants to attach to other molecules and it will do that by stripping your body of minerals such as calcium. Pure water is actually a very good solvent. So re-mineralizing water is not just about adding taste. You shouldn't want your water to read 0 on a TDS scale. The important part I wanted to mention was this system comes with it's own built in water pressure booster. This is important because the proper pressure is needed to make an R/O system work properly and to minimize waste water. An R/O system can not do it's job correctly if the water pressure isn't within the range of the specific R/O system you are using. Since this company knows exactly what that pressure should be, because it's their equipment, the booster pump delivers the proper operating pressure at all times. This water is simply a pleasure to drink. SUPPORT: The seller was fantastic to work with. Like I've stated in the past I've tried these systems before from other companies, and my opinion of good water is that it should have 0 after taste and almost feel like air going down. You should taste nothing as hard as you try. Well when I first put in this system and ran through all the startup protocols I found I wasn't getting the taste I expected and the TDS read really high. To put it in perspective the poland spring water bottles I tested in the 16oz plastic size came to about 30-35 TDS very consistently. Almost always 30 on the dot. So remineralized water from an R/O system should not be above that in my opinion because then water starts to have a "taste". Mine was above that and it had a distinct metallic after taste. I contacted the seller, explained how the install went, completed the protocols they asked me too and while still not completely happy they shipped me additional parts to swap out. All this happened within just a few days. So between response time, being empathetic to my problems and providing a tangible fix these guys we're great. The only reason I wrote this long review is because I remember my journey from just learning about these systems and what to expect from them health wise. And if I can compact as much important information as possible maybe your journey into picking the right solution for yourself can go quicker and less expensive then mine. Also any seller, especially on Amazon that makes a customer fell like their issue is super important deserves the accolades that I am happy to give.Between this seller and the product you will not be let down. Good luck everyone and a thank you to other reviewers that helped guide me in my own confusing purchases. If you reach out to the seller or customer service ask for SEAN. He was the best!

Overall, I like my system. It was a little more complicated but I did get the top system with like 90 stages(I'm joking, more like 7 - UV/Pump/mineral restore) .. so it being complicated makes sense. I did mess it up at the start so I was down a couple of days but I got a replacement part pretty quickly. Before I had a Whirlpool WHER25 RO system for about 11 years so I will be comparing with that. I replaced it because it was getting a little aged. I really liked the Whirlpool WHER25 also and would also give it 5 stars. Both systems are good for different people I would say. - The iSpring gives you many more options. (the Whirlpool just gives you one choice) Pump option, UV option, mineral restore option, plus other versions. - The Whirlpool is much simpler to install and work with. It is simply a much simpler unit. It is much easier to assemble and a tad easier to replace the filters. If you are not an DIY person then I would recommend the Whirlpool. - Tech support is excellent. I called support(Nick) picked up up right away. I guess I put part of it together incorrectly (forgot to pull off the rubber protectors on the RO) and it cracked the RO housing. I sent support a picture and he sent out the replacement by FedEx. It was shipped Monday and I think got here on Wednesday. (I never had to call support for my Whirlpool so I am not sure on that.) - The initial costs are close (when lease expensive 5-stage iSpring $190 to 3 stage Whirpool $150) however the filters are cheaper on the iSpring after. The iSpring filters are also much larger, so I would think you get more milage but I cannot say for sure. - I would say there is less chance of a water leak on a Whirlpool. My Whirlpool never had a leak in the 10 years I had it. It just really three joints. (1) from the home water (2) one to the tank (3) one to the waste water (4) to the faucet. The iSpring on the other had has maybe has many joints. - iSpring (at least the line I bought) starts at 5 filters and has a pre-sediment filter. If you have terrible water this sediment filter might be useful. (but I am not an expert) - I guess the biggest reason reason for the iSpring (over the Whirlpool) was that with the Whirlpool I was throwing away a lot of plastic...basically the filter, the plastic cylinder casing, the rubber O ring were all tossed each time. The iSpring just replaced the filters but it is a tad more work. Note: O rings can get old and hard so I'm wondering if I might still need to replace that every few years... not sure. Anyway, points to iSpring as far as the environment. - Industrial restaurants have filters similar to the ispring one so it seems to be the more industrial setup. - the Whirlpool WHER25 was a consumer reports top pick (at least when I bought it around 2009). The iSpring has not been reviewed - I am guessing because there are so many these days. - The iSpring is way larger than the Whirlpool. This caught me by a surprise. Luckily I was able to move my mineral/UV Lamp from the top to the side to make it fit. I would recommend measuring your space and also make sure you have a little extra space. I would also leave extra length on the tubes on the iSpring because you might need to pull out the complete unit (like if it is stuffed in the corner of the sink cabinet like I have it) - The iSpring came with lots of extra parts and a better quality sewer saddle. The Whirlpool didn't but it was a simpler setup. I don't think my Whirlpool one had a shutoff valve however the iSpring did. That is a parts may want to buy separately with the Whirlpool. Anyway, iSpring those lots of extra parts in the box for special setups. - I would recommend having a TDS water meter if you don't have one. This will help tell you if you system is not working correctly and when the filter need to be replaced. I would also keep a small running history of the tap water and post RO water history. So in summary, if you are a little handy with the tools, using more water, need a pump or UV or special filters, like throwing out less plastic, like cheaper filters then go with the iSpring. If it will only be used by a couple people, your water is not terrible like well water, you want to minimize the chances of leaks, or there is not much space, then go with the Whirlpool. (Again, I really liked that system mostly because it was simple and small.) This is way longer than I planned. Hopefully, it helps some people out there and also iSpring/Whirlpool if they see it.

Folgte der Anleitung und installierte die Anlage selber. Hatten vorher Rost von der Leitung und Kalk im Wasser, jetzt haben wir das Beste Trinkwasser was du jemals probiert hast mit dieser Anlage, und Francis vom Kundenservice hat sehr geholfen bei den fragen was ich noch hatte wegen dem Filterwechsel

Tengo este equipo comprado desde hace mas de un año, puedo decir que estoy encantado con el, ayer cambie los filtros por primera vez, todo muy facil, recomiendo el equipo y sus filtros.

Ho acquistato questo prodotto nel 2022. Per essere precisi il modello I-Spring RCC1UP-AK 100GPD L'ho montato da solo anche se devo specificare che ho una buona manualità, e le istruzioni sono molto chiare. Ho cambiato i filtri secondo gli intervalli previsti, acquistandoli sempre su Amazon con un costo accettabile e sicuramente inferiore a quello dei vari contratti di manutenzione per altri sistemi sul mercato, tra l'altro con una filtrazione molto ma molto inferiore al sistema I-Spring. Ne sono estremamente soddisfatto perchè: 1) L'acqua potabile è molto buona; 2) Da quando lo ho installato non ho più dovuto acquistare acqua in bottiglia e sobbarcarmi i relativi sforzi per movimentarla 3) Sto destinando ad altro uso lo spazio prima destinato a magazzinare le bottiglie d'acqua; 4) Risparmio al Pianeta tutta la plastica delle bottiglie usa e getta; 5) Non certo in ordine di importanza, questa azienda ha un ottimo Servizio Clienti: hanno sempre risposto in tempi brevissimi risolvendo i (piccoli) problemi che ho incontrato sia in fase di installazione che di uso. Al punto che, a distanza di due anni dall'acquisto, mi hanno inviato gratuitamente un pezzo di ricambio per un piccolo problema del sistema. Ottima esperienza: consiglio il sistema a tutti.

Second time I have ordered the filter and every time it was damaged and broken. I asked to take it back, and nobody has came to pick it up 2-3 weeks!
