iSpring RCC7AK 6 Stage Reverse Osmosis Water System Under Sink with Alkaline Remineralization, NSF Certified, 75 GPD, TDS Reduction

For more than 6 years I am happy that I found this system from a reputable brand and did not try to save a bit for cheaper alternatives. Here are my, time tested observations: 1. Installation Very easy to fit. It's fully DIY'able as long as you're able to connect it to the water supply. If you can't - don't worry, as in some cases there might be more complicated connections, where you need additional fittings like in my case, etc. In general - don't worry, no offence by no means as some people never did anything DIY, worry of flooding stuff, don't have tools, etc. it's completely fine. I am just saying that it can be done relatively easily and does not necessarily require a plumber :). But if you try it yourself, you'd be surprised how much you can do, especially with all youtube at your hands - become proud, stop being afraid of your handyman dreams and eventually start a full DIY renovation of your house haha! Joke with real background!) 2. Solid Quality. I've seen and serviced filters before, including at my friends and parents house and this one looks very well made when it comes to pipes, plastic housings, rubber rings, etc. Well, 6+ years so far is not a bad run, isn't it? The only weak point in my case is the filtered water faucet - it's leaking for a while inside the sink, but in fairness it saw so much pulling and twisting by my kids that I don't blame it. 3. Water quality & Taste Water quality was tested several times in the beginning and after filter changes and it is brilliant. Both pH wise and TDS (remember that it's mineralized back so account for it). I am going to tell you a super basic and even silly observation but in 6+ years my kettle was never washed and it looks cleaner and shinier inside than when it was new. No joke. And why I said it's silly, because RO systems filter much more than sediments, but micro stuff like bacteria and some viruses, metals, pfas and much more. Taste - no taste, just brilliantly clean and "tasty" water, hard to describe but in my family's head it's like "what ideal water taste should be". 4. Servicing If you did not install it yourself, trust me servicing (changing the filters) is even easier. You stop the water flow in filter and tank, unscrew using provided key, filter out + filter in, close well and test in the end to make sure no leaks. You can follow youtube too. It is really not hard at all. Filters are always for sale and you can get good deals if you buy like a 1+ years supply. In my experience, at least with Dublin water quality, which is not bad - even first sediment filters live much longer than recommended and when I replace them, they are just slightly coloured. But this depends on the water quality in your area of course. To finish with, a RO system brings amazing value for your money and I highly recommend to get one for long term health benefits, as no other filtration systems clean the water to this level of purity. Drinking and cooking becomes healthier and so do you. This particular one is used by our family every day and I can responsibly recommend it. Hope it helps even a bit & stay well and healthy! Cheers

I have been using the iSpring RCC7AK 6-Stage Reverse Osmosis Under Sink Water System for a while now, and overall I’m very happy with it. The difference in water quality was noticeable almost immediately. The water genuinely tastes better than bottled water, and I now drink more water daily because of it. The water pressure is also very good for an RO system; it fills glasses quickly and doesn’t feel slow or frustrating (please see attached video). Installation was straightforward with clear instructions, and everything feels well-made and solid. I also appreciate that it’s NSF certified, which gives peace of mind about safety and TDS reduction. After checking with a TDS meter, the reduction is impressive. Pros: -Water tastes clean, fresh, and pleasant -Good water pressure for an RO system -Strong TDS reduction -NSF certified -Build quality feels durable and premium -Saves money vs bottled water Cons: -Takes up some space under the sink -Initial installation takes a bit of time if you’re not DIY-confident -Filter replacements are an ongoing cost (expected for RO systems) Overall: This is a reliable, high-quality RO system that delivers exactly what it promises: great-tasting water with strong performance. If you’re looking to improve your drinking water at home, I would definitely recommend it.

I really love this. It’s pretty big so you need quite a lot of space under your sink. The filters are big but filtered water goes into a tank and the tank is big too! My man is pretty handy and was able to install this himself but there are a couple of things to be aware of. It comes with American fittings so you need to buy flexi hose to connect it to our sink. It also comes with its own tap so needs space to install this which inevitably involves some drilling in the sink or work surface. Installation isn’t necessarily easy and depends on having the right tools and correct parts for the job. The tap is quite small and the water comes out quite slowly. However, the water looks and tastes clean. I can’t drink regular tap water now as it smells funny. You never really know whether these things are working. I live in a hard water area. My new kettle had limescale in it within a week. Since using this filter there is not one single speck of limescale… that’s good enough for me! The filters need changing once a year and are pretty competitively priced. As well as taking things out the water, this also re-mineralises with the things you want to keep. I’m really pleased with this and the water definitely tastes better!

I wish I knew about these filtration systems years ago as this is now one of my most important things I have bought recently. Pure clean water from my tap which tastes just like bottled water, it's really that good. I have no clue about plumbing at all and still fitted this up myself with no major problems. All I needed was a little fitting from my local plumb store so I could attach the supplied cold water feed to my own water supply. The system is hidden away under my sink and the new tap looks great. Everything works exactly as it should, I'm over the moon with it and I'll never be without one from now on.

I’ve installed the iSpring water filtration system for not just myself, but for my entire family—six households in total—and the experience has been consistently excellent across the board. The system itself is reliable, efficient, and delivers noticeably clean, great-tasting water. Installation was straightforward, and once set up, it runs smoothly with minimal maintenance. It’s given all of us peace of mind knowing we’re drinking high-quality filtered water every day. What really stands out, though, is the customer support. Nick has been incredibly helpful—always responsive, knowledgeable, and patient when answering any questions we had about installation, maintenance, or system performance. It’s rare to find that level of support, and it makes a big difference. Overall, I highly recommend iSpring to anyone considering a water filtration system. Between the product quality and outstanding customer service, it’s been a great investment for my entire family.

We’ve been using the iSpring RCC7AK system for a few weeks now, and we are genuinely impressed! The installation went smoothly, and the components feel high quality. Big thanks to Nick from the customer service team — he was extremely helpful and responsive throughout the registration process. One of the most impressive things: we’ve been using filtered water from the system in our glass electric kettle every day for two weeks — and there is absolutely no limescale at all. Not a trace. This alone is a sign of how well the system works. The faucet looks great and works perfectly, and the tank provides more than enough water for our daily use. Highly recommended! Thank you again, Nick — you’re doing a great job!

Ich habe lange nach einer zuverlässigen Umkehrosmoseanlage gesucht, da unser Leitungswasser hier sehr kalkhaltig und „hart“ ist. Gerade wenn man sich intensiver mit dem Thema Wasserqualität und Nährstoffaufnahme beschäftigt, merkt man schnell, wie sinnvoll ein solches System ist – und dieses hier erfüllt genau das, was ich mir erhofft habe. Die Installation war mit etwas handwerklichem Geschick gut machbar, alle Teile waren dabei und verständlich beschrieben. Besonders gefällt mir der zusätzliche Alkaline-Filter, der dem Wasser einen angenehm frischen Geschmack verleiht. Seit der Inbetriebnahme trinke ich deutlich mehr Wasser – einfach, weil es so gut schmeckt und man ein gutes Gefühl dabei hat. Für diesen Preis bekommt man wirklich ein hochwertiges System, das hält, was es verspricht. Absolute Empfehlung für alle, die Wert auf sauberes und gesundes Trinkwasser legen!

There is no price on health of you and your family. Great contact with Francis with minor issue regarding leaking tap, next day new one was send to me, no extra costs.

Estoy muy impresionado con el servicio al cliente que acabo de recibir de Ispring. Hace un año compré este sistema y me encantó porque el agua sabía muy bien y encajaba perfectamente debajo del fregadero de mi cocina. Hace unas dos semanas, dejó de entrar agua por los filtros. Llamé a mi electricista, quien lo arregló quitando la pieza que ya no funcionaba. Pero quería esa pieza y, viviendo en México, no la pude encontrar. Terminé enviando un correo electrónico a la compañía preguntando qué debía hacer. Sean me respondió en menos de 10 horas. Me pidió que le enviara una copia de la factura para asegurarse de que tenía la pieza correcta. Unas horas después me dijeron que la pieza estaba en camino y, a pesar de que la garantía estaba vencida, no me cobraron.
