iSpring RCC7AK-UV 7 Stage Under Sink Reverse Osmosis Drinking Water Filtration System with Alkaline Remineralization Filter and UV Sterilizer, 75 GPD

If anyone is considering buying a good water filter, look no further! The iSpring 7-Stage 75 GPD UV Ultra Violet Alkaline Mineral Reverse Osmosis Water System is what you want. If you think you might need help, do not worry! The customer service is excellent! They will make you feel nice and comfortable when you contact them. I am not sure if I can find the right words to express how fantastic experience I have had with iSpring exceptional customer service! But let's start from the beginning (not from Adam and Eve though, do not worry! LOL). Why I have bought a water filter. Most people do not know that the mineral water sold in plastic bottles is not healthy at all. There are 7 types of plastics and plastic containers are marked with a triangle of three "chasing arrows", which encloses a number giving the plastic type. The plastics which are typically used to hold water but also soft drinks, juice, sports drinks, beer, mouthwash, ketchup, and salad dressing are made from a plastic marked as number 1. That indicates that those containers are made of Polyethylene Terephthalate (PET). Although that plastic is considered to be safe, it contains antimony, a metalloid element with toxic qualities, which leaches from PET. The rate of leakage increases with temperature and can yield unhealthy levels in bottles stored in higher temperature. Antimony can cause acute and chronic health issues, such as diarrhoea, vomiting, and stomach ulcers. Brominated compounds can also leach into PET bottles. They can irritate the skin, mucous membranes, and tissues. If you bear in mind that even though the levels of toxins leached from PET could be considered as on a safe level, they may accumulate in your system over a period of time becoming a serious health risk. That is why I decided to install a multilevel water filtration system at my home. Why I have bought iSpring 7-Stage 75 GPD UV Ultra Violet Alkaline Mineral Reverse Osmosis Water System. The iSpring 7-Stage 75 GPD UV Ultra Violet Alkaline Mineral Reverse Osmosis Water System seemed to be the best offer on the market. It cleans your water from everything you need for a good price. I was not sure if I should order the system with or without the booster pump. I live in a big city and I thought the city water pressure should be strong enough to work with the system so I decided to go for the one without the booster pump. My buying experience. The order arrived quickly and before I even started installing the system, I received an e-mail from iSpring to thank for the purchase and to say that if the Feed Water Adapter (AFW) that taps into the cold water line did not fit my plumbing specifications, they would fully refund (shipping included) for the order of the AFWs that I needed. They included two links to AFWs which I could choose from. Once I ordered the AFW, I e-mailed iSpring customer service and almost instantly I was issued the full refund for my order! My installation experience. The installation of the system was easy. The package contained a very easy instruction with colour photos leading you through all the steps of the process. If you do everything as the instruction manual says, you will be fine. I did not have any problem at all, no leakage whatsoever. My surprise. Everything was fine but I noticed that my water tank stored only 2-2.5 litres of water. I wanted to use filtered water not only for drinking and cooking but also for washing fruits and vegetables and that volume of water was not acceptable for me. My contact with the customers service. I e-mailed customer service and they replied very quickly giving me a short check list. It was very easy to follow the instruction and give the system a check. The whole process took a couple of minutes. Further instructions made us come to a conclusion that my water pressure was below 45 psi and that was a problem. I needed a system with a booster pump. I was too optimistic thinking that my city water should be fine and I did not need the booster pump. Once we identified the problem, the iSpring customer service came with a solution. To make it easier for me and avoid possibly a bit complicated installation of the booster pump and its components on my existing system, they offered ordering a machine head with a booster pump factory installed. And here comes the best! As they understood that the water storage was of great inconvenience to me, they reduced the price of the machine head from 90 to 50 dollars! Since it had to be shipped from iSpring office in the United States, not the shop in the United Kingdom, where I live, that would generate some extra costs of shipping and the import tax. iSpring customer service offered me splitting the costs of shipping and the import tax! Solving the problem. My problem was solved. After installation the machine head with booster pump, the tank stores about 10 litres of water and that is what I need! I can hardly hear the pump working. The water pressure is very good and the tank fills up very quickly. The water tastes fantastic, much better than bottled water, no plastic aftertaste. My final thoughts. What else would you want from a customer service?! They could not do anything more or better! They are exceptionally kind, understanding, efficient, and professional! I highly recommend iSpring water to everybody. They are like a good friend, who is always around when you need them. I was very lucky having chosen iSpring and their product.

I’m extremely impressed with the water quality from the iSpring RCC7-UV7. The difference is noticeable immediately — the water tastes incredibly clean, fresh, and pure. It has completely removed the chlorine taste and any odours, and I feel much more confident about the quality of the water my family is drinking. The UV stage gives extra peace of mind, especially if you’re concerned about bacteria. That said, installation is not quick or simple. It took around 4 hours to complete and definitely requires plumbing knowledge. If you’re not confident fitting it yourself, you may need to hire a professional, which could cost up to £400 depending on your area. It’s not a plug-and-play system — proper plumbing work is required. Overall, if you’re prepared for the installation effort or cost, the performance and water quality make it absolutely worth it. Highly recommended for anyone serious about improving their drinking water.

Since we installed the iSpring RCC1UP-AK 100GPD Under Sink 7-Stage Reverse Osmosis RO Drinking Filtration System with the Ultimate Water Softener, Alkaline Remineralization, Booster Pump, and UV Filter, we've felt confident that our family is drinking safe, clean water. The installation process was straightforward according to our plumber, and everything needed was included in the package—no extra trips to the store or additional purchases required. The water tastes great, and everyone in the family has noticed the difference. A special thanks to Francis for his outstanding customer service. We had some issues registering the warranty, but with his help, everything was resolved quickly and smoothly. He was incredibly helpful and professional throughout the process—we couldn’t be more grateful. Highly recommend both the product and the support team!

Fits nicely in the tight space under the sink, produces clear clean water which tastes great. Installed in our newbuild, very happy.

Good but pricey. Tap is decent

We have been using a jug type water filter for many years, but needed something much better as we live in a very hard water area with loads of chlorine added, besides, it's not always the best tasting water. So I decided to go for the full 7 stage RO filter unit from iSpring and am pleased I did. The equipment arrived very quickly and was well packaged. I thought it best to have as much space for the unit as possible, so fitted the unit in a cupboards away from the sink, I felt this would work as I have the pumped unit and a longer delivery pipe should work well, which it did. Installation is not really a quick job if you want to make a tidy job, but it can be fitted quickly if needed. I did experience a few minor water leaks, but hay, there are a lot of places for it to leak, and I expect I twisted a few fittings during the installation anyway. By the end of the day, all was working great, water leaks sorted, and system flushed and clear. I have checked it a few times now and all is leak proof and working as expected. I would say the 7 stage unit is a bit top heavy, seems they add the extra units without re designing the brackets, so I added a couple of small shelf brackets and a couple of cable ties to make it more stable. I also have the UV unit, but be careful to mount the flow switch away from the unit slightly because it must be sensitive to magnetic forces as it often turned on without water flow and it gets quite warm if left on. It is easy to see when it is 'on' by looking for a little light escape from the plastic water fittings. Finally, communication has been great between me and iSpring, and they offed advice and help freely. Remember though, you might need a different water connection than the one supplied but iSpring will supply what you need, however I did make up an adaptor with a fitting from the plumbers shop to fit my 15 mm pipe work. Yes I would recommend this unit, and the water it delivers is great.

I've long been aware of the concerns surrounding tap water quality in the UK. From chlorine taste to potential contaminants like fluoride etc., it's understandable why many people opt for bottled water. However, the iSpring RCC1UP-AK 100GPD Under Sink 7-Stage system has provided a reliable and affordable solution to these issues. I've been using the iSpring RCC1UP-AK 100GPD Under Sink 7-Stage system for over a month now and couldn't be more pleased with my purchase. After experiencing persistent limescale issues with our previous Brita kettle, the iSpring system has been a game-changer. The water quality is noticeably superior, resulting in improved taste and a noticeable difference in cooking outcomes. Additionally, the system has significantly reduced our reliance on bottled water, making it a more sustainable and cost-effective choice. The installation process was straightforward, and customer support was incredibly helpful in guiding me through the registration for the extended warranty. Overall, I highly recommend the iSpring RCC1UP-AK to anyone seeking a reliable and efficient under-sink water filtration system.

We have a private water supply, and where we live in the Scottish Highlands our water supply has high levels of tannin (peaty coloured water). UV sterilisation systems work less effectively in less than very clear water. Therefore, having an under-sink RO filtrations system offers an alternative approach to cleaning the water supply. I’ve fitted and maintained at least three under-sink ROs in the past. What I really liked about the iSprings RCC 1UP-AK 100GPD system was how much thought has been put into the pipework design - with each pipe colour coded and easily identified during the installation and commissioning process. The fitting instructions are very clear, and I’d also recommend looking at the installation videos on the iSprings website for further guidance and tips. The RO membrane (stage 4 of 7) does a fantastic job of removing the tannin colouration (and other impurities) from the source water meaning that the UV on the final stage (7), can do its job properly. Peaty water is generally a little acidic, and combined with the RO process can make the resulting filtered water even more acidic. Stage 6 of this 7-stage system is an alkaline filter that is aimed at rebalancing the PH closer to neutral (i.e. PH of 7). Another observation is that the electrical pump is very quiet. Once the under-sink cupboard door gets closed it’s really difficult to hear the pump operating - so there is no disturbing background noise. A final comment, I like the quality of the RO systems so much that I’m now going to purchase another of the same for a holiday home rental that we have nearby.
