iSpring RCC7P-AK, 6-Stage Reverse Osmosis System Under Sink Alkaline Water Filter and Pump, RO Drinking Water Filtration System, Patented Top-Mounted Faucet Design for Easy Installation

Product seems to work well and you can definitely taste a difference in the water, to the good. I blind taste tested with my family and everyone picked the water from this filter (vs our previous one). It was easy to install with good instructions and many available youtubes videos if needed. Everything seems to be well designed and well made. I did run into an issue with my tank but Nick at customer service troubleshooted the issue and immediately sent out the replacement part. Honestly it was a refreshing change in how easy and responsive they were.

I’ve been using the iSpring Reverse Osmosis System for a while now, and I couldn’t be happier with the results. The water quality is outstanding—clean, crisp, and noticeably better than what we had before. Installation was straightforward, and the system has been running smoothly with minimal maintenance. I’ve been so impressed with this system that I’ve installed it not only in my own home, but also for my parents and a couple of friends. Everyone has had the same great experience. What really stands out is the customer support. Nick from the support team was incredibly helpful, knowledgeable, and patient—he made sure all my questions were answered and everything was set up perfectly. That level of service is hard to find. Highly recommend this system if you’re looking for reliable performance and excellent support behind it.

I bought it in December 2025. Relatively easy to install. I’m really glad I did. My well water really tastes awful! There was no way I could’ve installed it under the sink, it would’ve made it extremely difficult to change the filters. I bought some more plastic tubing and I ran it through the cabinets and next to my washing machine. I built a little caddy so I could pull it out and access everything easily when I need to and I didn’t lose that very valuable cabinet space . I was a little bit afraid of adding extra length to the hoses, but if it made any difference, it seems negligible. It works great for me. I’m a single person, but I do drink a LOT of water. I am especially glad that I got the electric booster pump! I can’t imagine this thing pumping clean water using the pressure from my water system! To me it seems like it would have to be using like hundreds of gallons (cumulatively) of water to pump 3 gallons of filtered water. The pump is VERY quiet. I was very happy about that. You can barely hear it at all. As far as I can tell it pumps nice clean water and I’m really glad that it re-mineralizes the water! We have extremely hard water here, I was getting plenty of calcium and magnesium, I did not like the idea of losing that source of minerals, but hopefully so far so good. Thank you I am very happy with my purchase. I’m glad I didn’t get the super basic model.

Florida is not noted for its delicious drinking water and Sarasota is no exception. To rectify this I ordered an iSpring RCC7P-AK reverse osmosis under-the-counter water system from Amazon four years ago. I am not the quickest guy in the world when it comes to putting things together but it was was relatively easy to set up because the instructions were clear and the company has posted a step-by-step YouTube video to facilitate the process. The taste of my water is now much improved and the unit worked flawlessly for four years with semi-annual filter changes until a few weeks ago when the flow was very slow coming out of the unit. I called the iSpring customer support telephone number and was pleasantly surprised. Instead of encountering an answering machine with a long menu of options to choose from interspersed with music and product offers while I answered the questions and waited in line for an agent to answer, a real person actually answered my call. And not just any person, but a trained technical services representative named Nick. Nick asked why I was calling, I explained my problem and he immediately began troubleshooting it over the phone. He suspected my pressure tank was probably low in pressure and recommended that I empty the water tank, adjust the pressure with a bicycle pump and pressure gauge and then give it a couple of hours to refill. He told me the procedure was clearly explained in an on-line YouTube video which he told me where to find. He finished by saying if I had any questions or problems to feel free to call him back. I did as he directed and for a while the RO output water pressure was fine. However after about a week it reverted to being super slow again. So I called the iSpring customer support telephone number again and, just like the last time, it was immediately answered by Nick. I explained that the output RO water pressure was low again and that I had checked the pressure in the tank with my pressure gauge and that dirty water had spurted out when I checked the pressure and the gauge read 70 psi, which is 10 times what it should be. He concluded that the tank had a ruptured diaphragm and needed to be replaced. He asked me how old the unit is and when I told him he said it was out of warranty. I prepared myself for the worst, figuring it was going to be expensive to replace. To my surprise he said he would send me a new one at no cost if I would send me an Amazon proof of purchase receipt which I promptly supplied. The following business day I received a mail saying the replacement pump was being dispatched. Now that is what I call customer service. Hooray ISpring, Hooray Nick!

Very nice quality system, replacement filters are affordable and so far I've experienced great customer service from an AMERICAN based company. I had to contact the manufacturer for a quick verification to an inquiry I had. To my surprise a native English speaking (I have an auditory processing disorder making it hard for me to understand regular conversations let alone a conversation with someone who speaks with a heavy accent) HUMAN representative answered the phone and my inquiry in 2 seconds. This really validated any concerns I had about my purchase. I've had a cheap RO system before so I'm somewhat familiar with how RO systems work. This time around I wanted a beefier/better filter for my "new" house as my plan is to use the system for ANY water to be consumed. I bought the model with the electric pump to process the RO water a little faster. The untreated water is 'forced' through the RO filter and rely on line pressure to do so. The unit with the electric pump helps generate clean water a little faster and keep better pressure on the system. Although this is an under-sink filter system, I opt'd to install mine in the basement underneath where the kitchen sink is. Regardless of where you install it, the system installed quick and easy. This is designed to be installed in-line with the kitchen sink so if you want to do a basement installation like mine, you will need some additional parts to make it work although this is not a typical setup. Overall, I'm very happy with the quality of the items, the quality of the water and taste. It's even improved the taste of the coffee. I would recommend to friends, family, and strangers looking for a water filter. Unrelated to the product itself (specifically Amazon): BUYER BEWARE, as you should be with anything you buy on Amazon. I bought this 1 week before prime day (July 8, 2025) knowing it might go on sale in a few day but I wanted to install it over the holiday weekend as I was off of work. I contacted Amazon via their chat bot and was told by an Amazon representative to go ahead and buy it and if the item went on sale, they would "work with me" but was also told they didn't offer price matching on sales. OK, I thought...they said they would "work with me" and I took that for more than it was worth and foolishly ordered the item. Of course, the item immediately went on sale during Prime Day for almost $70 less. I would have been ok with say $7 less from a sale but it went on sale for $70 less. That is a huge price difference and when I contacted Amazon for them to "work with me", they acted as if I was the crazy one and that the representative never said that. Well, they did offer me a "courtesy credit" for the difference but that isn't cash back, that is a credit to your amazon account that can only be used on Amazon.com sold items. I still had to pay the full amount to my credit card company. Anyhow, they also did tell me I could purchase the new item then return the original item to get the lower price. I [again] foolishly didn't do this but should have...so my point is, play the Amazon game and do your due diligence to get the best price because Amazon doesn't care if the item is 3x more or less, they ain't voluntarily offering you anything better unless you kick and scream and then MAYBE they'll offer you a courtesy credit that can only be used on select items. Don't let Amazon be the reason you don't purchase this filter. The above paragraph is specific to Amazon, not the device.

Here I am 4 years later adding to my review. Recently had a leak from the top of the second stage. We use are water quite a bit so I am sure it has some good use. I contacted customer support, and once again they were 20 out 10. Nick has been helping me for the past few years, and he is on top of everything. They sent me a new system even though it has been a few years since the purchase. Not only that, he threw in a pressure regulator that could have been the cause of the leak. Anyone that is browsing for this product, I cannot recommend it enough. The product is great, the water is very enjoyable, and the customer support is the best I have ever had. Coming back 2 year after my first review. Once again, I am grateful for such a great customer service. Today I was replacing my filters and assumed the nipple on the membrane spins like the others. It does not and I broke it. Contacted customer service and this time I was helped by Nick. He is sending a replacement today at no charge. My system is just a little over 4 years old. With regular minimal maintenance the system work like it is new. I am very happy with this system and highly recommend to any that are interested in getting it. Water taste good and it's easy to assemble. Best of all, customer service will not let you down. I have had the 6 stage system for about 2 years now. To start off with, the install was easy to do while following the instructions. The water taste great once you remove the first batch after replacing the filters. Pressure coming out is decent, though I will say I wish it was a little quicker. During the 2 year period, I have only had 2 issues. One is the diaphragm inside the take must have been faulty or come loose, allowing for pressure to drop and making the pump continuously run without stopping. Some may see this as a negative but I expect for items to occasionally have a bad apple. I called and spoke with Don and he was able to troubleshoot the issue quickly. Not only did he troubleshoot it he replaced the take and system immediately. Don was amazing on the phone and I could not have asked for better support. Once the new system arrived, everything worked smoothly. My second encounter was after this Texas storm. With boil water warning in place in our area for 2-3 days, it is recommended to replace filters. Unfortunately Amazon did not have the 6 stage available so I reached out to Ispring again. I had the fortune of dealing with Don again and once again he was amazing. He suggested I get the 5 stage and he would supply me with the 6th stage that was missing. They truly care about their customers. Their website has the filters priced a little more and they still have you go on Amazon to purchase it for a lower price. I would recommend this product to anyone interested in getting it. System works well, water taste great, and the customer service incredible. Thank you Ispring!!

We had the same iSpring water filtration system in our previous home for over 10 years and honestly had zero issues with it. The water quality was excellent — clean taste, no strange aftertaste, no buildup or settling in our teapot, and overall just consistently great water. We completely stopped buying bottled or filtered water elsewhere because this system worked so well. So when we moved into our new house, I didn’t even hesitate — I purchased the exact same system again. We did run into an issue with the new pressure tank, but Sean from iSpring customer support was outstanding. He helped us quickly identify the problem, walked us through troubleshooting, and promptly sent a replacement tank. Extremely professional and helpful throughout the entire process. Now we’re back to having pure filtered water right from our kitchen again — no plastic waste, super convenient, and excellent water quality. Definitely a product and company we trust.

The filter is now installed and is working well for several weeks. It is very easy to use, and although it seems like changing the filters will be a pain, it only has to be done between every 6 months to a year. I tested our tap water with a PPM meter and it was in the 40s (actually not bad), but after running through the RO system it is down to 14 PPM (probably would be closer to 0 without the trace minerals added back in by the system). The installation however, was not a piece of cake, and it took my husband and I close to a day to complete (and we are pretty handy). We already had an extra hole in our sink, so we didn't have to drill that, but because we live in NYC we did have to drill though the metal drain pipe (which apparently is only required in NYC). The most difficult thing however, was troubleshooting the system, where it was stopped up in several places. The instructions are sub par (and not specific to having the pump or the additional mineral filters), and the company is not available on the weekend for tech support. The plastic tubes need to be pushed in a a full 1/2", farther than it seems necessary, or they will leak (which happened with all of our connections). In addition, several of the connections that were set at the factory were faulty, and we had to take them all apart and put them back together to get them to work. So, an incredibly frustrating day all around. Also, even after draining the first tank per the instructions, the second tank had a milkiness to it that didn't dissipate, so we had to drain the tank a second time. By the third tank the water was clear. The taste isn't amazing, but it beats tap water. My husband also likes to run it through the Brita as well, which he says makes it taste better. One very important thing to note, although there are systems that will work on water pressure alone, this system will not work without power to the pump, so make sure it is plugged in when you're ready to test the system. Also, the pump will only pump when it senses a lack of pressure, so if you're troubleshooting you may need to drain parts of the system to get the pump to activate after troubleshooting. Now that it's installed, we like it a lot, and we haven't had any issues. The faucet is attractive. We did set up the leak detector, but we haven't had any leaks. I usually take a large bottle of the filtered water with me to work, and I have noticed I drink less water overall; the RO water doesn't make me thirsty like regular water. Considering that I used to drink tons of water (way more than necessary), this is a huge improvement.

Absolutely amazing when you compair 2 glasses of filtered and standard tap water side by side the difference in water quality is alot filtered is crystal clear for the first few weeks its tasteless and does leave a slight dry sensation in your throat but after the first month of using it it's gone from ph7 to ph27 so I guess the remineralizate filter has started to work I wouldn't drink standard tap water now this water tastes much better I give it 10/10 it was also very easy to fit myself buy a cheap digital ph pen off here it will show you the state of your filters when the phone increases over time also to check against your standard tap water love it

Estoy en México y compré este sistema de purificación, vino con una falla en una de las válvulas. Me comuniqué por correo al servicio de ispring y me mandaron repuesto de todas las válvulas e incluso me regalaron un filtro por la molestia. No hay soporte técnico en México, solo en USA y es por correo, porque no responden el teléfono. Solo responden un correo al día aunque les mandes varios. La falla que presentó mi sistema, la detecté yo y fue después de hacer muchas pruebas, incluso usé un multimetro. El soporte que me dieron fue básico, prácticamente les comenté del error y les dije cuál creía que era la falla y ellos no me preguntaron más y mandaron el reemplazo de las piezas. Si se necesita conocimiento técnico para poder reemplazar las válvulas y ellos solo me dijeron avísame cuando la instales, yo me las arregle para hacerlo. Iba a calificar mal el producto por la mala experiencia, pero llevo 2 semanas con el sistema trabajando y la verdad es que me encanta. El agua sabe muy bien, el motor es silencioso, si tienes baja o alta presión no importa porque la bomba viene con válvulas que regulan la presión. El agua del grifo sale a muy buena presión y pues ya fuera de la falla técnica que tuve, estoy muy contento con el producto. Se me hace de excelente calidad y por eso le doy 5 estrellas. También debo mencionar que iba a devolver el producto y el vendedor me aprobó la devolución, no lo devolví porque realmente quería probar este producto y el servicio de ispring me mandó los reemplazos, que tardaron como una semana en llegar. Así que al final cancelé la devolución y me quedé con el producto ya arreglado. Lo recomiendo pero te arriesgas a que si tiene una falla debes de contratar un técnico para que te ayude a verificar la falla e incluso para que instale los reemplazos.

Pour le Packaging, rien à redire, c'est trés pro et trés bien embalé. Coté installation, c'est une première pour moi mais il faut reconnaitre que c'est assez facile, les cartouches sont bien identifiées car préinstallées dans leurs receptables sauf la membrane qui est la plus sensible (évitez de toucher avec les doigts pour ne pas contaminer), il suffit de la laisser dans son emballage en coupant le sac plastique coté 2 joints toriques et de la pousser dans le filtre (respectez les flêches présentes sur les emballages). Pour la suite de l'installation, il suffit de suivre la procédure pour purger l'installation et vidanger le réservoir, à noter que la documentation est claire et en plusieurs langues dont le français. La pompe est trés discrète, elle me permet d'utiliser l'eau osmosée sur un frigo américain et un évier (il suffit d'installer un T sur la sortie (bleu). Petit conseil : s'assurer de bien "pousser" le tube dans les raccords .Notez que les tubes livrés sont tous marqués par un trait qui permet de voir si le tube est enfoncé à fond, bonne idée). Merci à Julius pour son suivi.

I am really surprised by the quality of the product and the result of the filtered water. I bought a device with mineralization, and the resulting water is very pleasant to drink. The installation was also very smooth; it is quite basic, as you just need to fit the proper hoses into the proper places. The installation kit includes everything that everybody needs. It has 2 different types of connections for different water supply systems: one is 1/2 inch and the other is smaller. I can only suggest this for anybody seeking water purification. I can hear the pump, but it is very silent and does not make any strange noises. It is not bothersome, and once you are used to it, the sound completely disappears into the surrounding noise of the kitchen. In terms of performance, the tank fills in about an hour or so, and the pump really helps to make this process faster. I also like the quality of the metal parts, such as the component you install into the faucet. It is not premium, but it is very nicely built. You will not regret buying it.
