Other iSpring RO Systems RCC7AK RCC7AK-UV RCC7P-AK RCC1UP-AK RO400 Review: More than 6 years of drinking brilliant water! - 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 Review: Clean, great-tasting water with strong pressure - 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. ## Features - 【Certified to NSF/ANSI 58】: 6-Stage Alkaline Remineralization Layered Filtration - Exclusively designed to restore the natural alkalinity and mineral balance of water; this reliable and ultra-safe Reverse Osmosis (RO) water filtration system converts your water into clean, pure and healthy drinking water by removing up to 99% of over 1,000 harmful contaminants like chlorine, fluoride, lead (removes up to 98%), arsenic, asbestos, calcium, sodium and more. - 【GREAT-TASTING MINERAL WATER】：A standard 5 stage RO system produces slightly acidic water with a pH of 7. 0 or below because the RO membrane removes not only harmful pollutants but also a few helpful minerals. The iSpring RCC7AK Reverse Osmosis water filter includes an additional 6th stage - an Alkaline Remineralization filter which restores healthy minerals and produces a balanced alkalinity, which gives your water a more natural taste than regular 5 stage RO water filter. - 【LOW MAINTENANCE】：Transparent 1st stage housing for easy visual inspection. Three extra long life pre-filters to remove large contaminants and protect RO membrane. Ultra fine (RO) filter to remove contaminants down to 0. 0001 microns; fine GAC filter to provide final polishing to the purified water and (AK) filter to finally restore just the right proportion of healthy minerals and a natural alkaline balance. The end result is great-tasting bottled-water quality. - 【EASY TO INSTALL & NO LEAKS】: The water purifier is designed for do-it-yourself installation and all necessary parts for installation are included. Backed by clear installation manual, instructional videos, and access to life-time technical support. The entire alkaline water filter fits nicely under a kitchen sink. For leak-free installation, simply push tubing ½ inch deep into quick-fitting connectors and lock; no threading pipes needed. - 【100% SATISFIED CUSTOMERS】: RCC7AK from America’s favorite brand of under sink water filter is the highly rated reverse osmosis systems. Comes with 1-year limited manufacturer warranty upon registration and lifetime personalized support from GA, USA, combined with premium quality components, this water filter is to deliver endless bottled quality drinking water right in your home for many years to come, eliminating plastic waste. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005LJ8EXU | | Best Sellers Rank | 46,892 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 8 in Water Filter Taps | | Brand | iSpring | | Capacity | 75 gallons | | Container Type | Dispenser | | Country Of Origin | China | | Customer Reviews | 4.4 out of 5 stars 13,522 Reviews | | EU Spare Part Availability Duration | 3 Years | | Global Trade Identification Number | 00662425038015 | | Included Components | filter | | Included components | filter | | Installation Type | Under Sink | | Item Dimensions L x W x H | 39.4L x 13W x 49.5H centimetres | | Item Weight | 20 Pounds | | LowerTemperature Range | 40 Degrees Fahrenheit | | Manufacturer | iSpring | | Manufacturer Part Number | RCC7AK | | Material | Plastic | | Material Type | Plastic | | Maximum Flow Rate | 2 Litres Per Minute | | Model Name | RCC7AK | | Model Number | RCC7AK | | Operating Pressure Range | 70 PSI | | Other Special Features of the Product | Multi Stage Filtrartion, NSF certified | | Power Source | Corded Electric | | Product dimensions | 39.4L x 13W x 49.5H centimetres | | Purification Method | Reverse Osmosis | | Smart Home Compatibility | Not Smart Home Compatible | | Special feature | Multi Stage Filtrartion , NSF certified | | Supported Water TDS Level Maximum (PPM) | 750 | | UPC | 662425038015 | | Unit Count | 1.0 count | | Upper Temperature Rating | 100 Degrees Fahrenheit | ## Product Details - **Brand:** iSpring - **Capacity:** 75 gallons - **Included components:** filter - **Installation type:** Under Sink - **Material:** Plastic - **Package information:** Dispenser - **Power source:** Corded Electric - **Product dimensions:** 39.4L x 13W x 49.5H centimetres - **Purification method:** Reverse Osmosis - **Special feature:** Change Filter Indicator ## Images ![iSpring RCC7AK 6 Stage Reverse Osmosis Water System Under Sink with Alkaline Remineralization, NSF Certified, 75 GPD, TDS Reduction - Image 1](https://m.media-amazon.com/images/I/71FIqfWoK0L.jpg) ![iSpring RCC7AK 6 Stage Reverse Osmosis Water System Under Sink with Alkaline Remineralization, NSF Certified, 75 GPD, TDS Reduction - Image 2](https://m.media-amazon.com/images/I/71W+lvTfiLL.jpg) ![iSpring RCC7AK 6 Stage Reverse Osmosis Water System Under Sink with Alkaline Remineralization, NSF Certified, 75 GPD, TDS Reduction - Image 3](https://m.media-amazon.com/images/I/71ZL4lIeuEL.jpg) ![iSpring RCC7AK 6 Stage Reverse Osmosis Water System Under Sink with Alkaline Remineralization, NSF Certified, 75 GPD, TDS Reduction - Image 4](https://m.media-amazon.com/images/I/71GlVb75E7L.jpg) ![iSpring RCC7AK 6 Stage Reverse Osmosis Water System Under Sink with Alkaline Remineralization, NSF Certified, 75 GPD, TDS Reduction - Image 5](https://m.media-amazon.com/images/I/711XSlaClJL.jpg) ## Questions & Answers **Q: Hi! What pH does your filter produce??? Does the remineralization filter only contain natural, pure minerals? Do you knox approx mineral composition?** A: The ph value on my system comes out to just on the acidic side i have spoken to the company and they have sugested I buy another alkaline filter (FA15) .. as this is part of my system i feel this has come up short !! I am thinking of (Inline Alkaline Alkaliser Water Filter Cartridge Increases pH for Reverse Osmosis Water Filter Systems Easy Add On In-Line Cartridge) this is on the Amazom sight and comes from a company called (The Water Filter Men) I will let you know how this goes. **Q: Sorry if this is a silly question but does this system filter the entire supply throughout the house, shower etc (not just a single tap) ?** A: No this system will only supply a single tap. **Q: Are there any special adaptors i need for uk, if so how can i order this with the unit or does it come all ready for uk installation?** A: I bought this system for use in the UK and am having a problem connecting it to the main water feed; the supplied parts will not allow for connection to my incoming water supply. I need your recommendation on how to connect to a 15mm copper pipe for the supply, and push-fit flexible connector from the existing tap (faucet). **Q: Hi . Can this system be used to filter rainwater into drinking water ?** A: Hi, This system is recommended for city water/municipal water sources or well water sources. It is not recommended to be used with rain water as the total dissolved solids for the rain water would exceed the max TDS recommended for the system. Also with Rain water, there is also a change for microbial growth or bacterial contamination of the rain water.

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! ## Frequently Bought Together - iSpring RCC7AK, 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 - iSpring F9K NSF Certified 1-Year Reverse Osmosis Water Filter Replacement Pack, Alkaline Remineralization Filters for 6-Stage RO Systems, Without RO Membrane - iSpring ICEK Ultra Safe Fridge Water Line Connection and Ice Maker Installation Kit for Reverse Osmosis RO Systems & Water Filters, 1/4", 20 feet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/48256489-ispring-rcc7ak-6-stage-reverse-osmosis-water-system-under-sink](https://www.desertcart.tn/products/48256489-ispring-rcc7ak-6-stage-reverse-osmosis-water-system-under-sink) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
