Awesome customer service. FLUSH PRE FILTERS DURING INSTALL. Can recycle drain water. - We recently installed the iSpring RCC7AK reverse osmosis water filtration system, and we've been very happy with it. The installation was straightforward, but it's worth taking your time and carefully following each step. We did run into one issue because we went back and forth between the YouTube installation video and the manual and overlooked the step of flushing the three pre-filters until the water ran clear before connecting the RO membrane. As a result, the RO membrane became clogged, and the system wasn't functioning properly. I reached out to customer support, and Laurence provided outstanding service. He was responsive, knowledgeable, and guided me through the troubleshooting process via email. He even sent detailed video instructions on how to check the tank pressure. Once we determined that the RO membrane had become clogged during installation, Laurence promptly express-shipped a replacement. After installing the new membrane, the system has been performing exactly as expected. With our water pressure at 65 psi, we're seeing a wastewater ratio of approximately 2.5–3:1, the flow rate is excellent for filling bottles, and the water tastes noticeably cleaner and fresher. It's reassuring knowing we're drinking high-quality filtered water every day. One modification I made was adding a tee fitting and shutoff valve to the 1/4-inch drain line. This allows me to divert the wastewater into a bucket for watering plants or simply close the valve and have it drain into the kitchen plumbing as originally designed. It's a simple addition that gives us the flexibility to reuse the water instead of letting it go down the drain. If you're looking for a reliable reverse osmosis system backed by exceptional customer support, I would definitely recommend the iSpring RCC7AK. Thanks again to Laurence for going above and beyond to make sure everything was resolved. Review: Excellent System, Easy Install - I've had this system for almost 3 years now and wanted to report it was an easy installation, easy to follow instructions, and has provided great tasting water for us the last few years. Recently it did develop a slight drip from the faucet valve so I reached out to see if I could purchase a replacement valve. Talked with Sean from ISpring customer service and although they did not have replacement valves, he promptly sent me a completely new faucet assembly to install, for free, even though the system was outside of the warranty. He was great to work with and resolved my issues at no cost, which was unexpected. Thank you and ISpring so much!!!! ## Features - PATENTED DESIGN – The top-mounted fastener allows for easy countertop installation entirely from above, eliminating the hassle of tightening the nut from underneath the sink. - MINERAL BOOST – The patent-pending natural mineral AK stage delivers spring water with a balanced, healthy pH and multiple essential minerals. - SEE WHAT’S CAUGHT – The transparent first-stage filter housing makes it easy to monitor contaminant buildup, ensuring timely filter changes. - NSF 58 CERTIFIED RO SYSTEM – Unlike other brands that lack NSF certification or full system certification, our RCC7AK is certified to NSF/ANSI 58 standards for the entire water filtration system. - EFFECTIVE FILTRATION – Reduces TDS (93-98%), PFAS (96-99%), Chlorine (95-99%), Asbestos (>99.7%), Barium (>98.4%), Cadmium (>98.8%), Chromium (>99.2%), Copper (>97.8%), Fluoride (>97.4%), Lead (>98.9%), Selenium (>99.0%), and over 1,000 other contaminants. - EASY INSTALLATION – The RO water system features a DIY-friendly design with quick-fitting connections, a clear manual, and step-by-step videos for a hassle-free setup. - TRUSTWORTHY SUPPORT – America’s favorite RO brand, backed by lifetime technical support in Atlanta, GA, ensuring expert assistance whenever you need it. - CONVENIENT REPLACEMENT FILTERS - Easy access to replacement filter sets: F4AK (6-Month), F9K (1-Year), F19K75 (2-Year), and F28K75 (3-Year). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005LJ8EXU | | Best Sellers Rank | #727 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2 in Under-Sink & Countertop Filtration | | Brand | iSpring | | Brand Name | iSpring | | Capacity | 75 gallons | | Container Type | Tube | | Customer Reviews | 4.6 out of 5 stars 15,100 Reviews | | EU Spare Part Availability Duration | 3 years | | Filter Life Cycle | 6 months | | Global Trade Identification Number | 00662425038015 | | Included Components | RO System, Brushed Nickel Faucet, Storage Tank, Extra Tool Set | | Installation Type | Under Sink | | Item Dimensions L x W x H | 15.5"L x 16"W x 18"H | | Item Type Name | Reverse Osmosis System | | Item Weight | 12.5 kg | | LowerTemperature Range | 40 °F | | Manufacturer | iSpring | | Material | Acrylonitrile Butadiene Styrene , Plastic, Polyethylene , Polypropylene, Polystyrene | | Material Type | Acrylonitrile Butadiene Styrene, Plastic, Polyethylene, Polypropylene, Polystyrene | | Maximum Flow Rate | 284 liters_per_day | | Model Name | RCC7AK-BN | | Model Number | RCC7AK-BN | | Operating Pressure Range | 70 psi | | Other Special Features of the Product | Multi Stage Filtrartion, NSF certified | | Part Number | RCC7AK-BN | | Power Source | No Power Needed | | Product Dimensions | 15.5"L x 16"W x 18"H | | Purification Method | Reverse Osmosis, Alkaline, Activated Carbon, Carbon block | | Special Feature | Multi Stage Filtrartion , NSF certified | | Supported Water TDS Level Maximum (PPM) | 750 | | UPC | 662425038015 | | Unit Count | 1 Count | | Upper Temperature Rating | 100 °F | | Warranty Description | 1 year manufacturer limited warranty | ## Product Details - **Brand:** iSpring - **Capacity:** 75 gallons - **Included Components:** RO System, Brushed Nickel Faucet, Storage Tank, Extra Tool Set - **Installation Type:** Under Sink - **Material:** Acrylonitrile Butadiene Styrene, Plastic, Polyethylene, Polypropylene, Polystyrene - **Package Information:** Tube - **Power Source:** No Power Needed - **Product Dimensions:** 15.5"L x 16"W x 18"H - **Purification Method:** Reverse Osmosis, Alkaline, Activated Carbon, Carbon block - **Special Feature:** Multi Stage Filtrartion, NSF certified ## Images ![iSpring RCC7AK-BN 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 - Image 1](https://m.media-amazon.com/images/I/81Ius7bMHaL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Questions & Answers **Q: What does this mean: "For each gallon of clean water, only 2 gallons of water are wasted"? Where does the wasted water go? How is this economical?** A: If your family drink 10 gallons of water per day. The waste water might equal to 10 flushes of your toilet. **Q: Where do I get replacement filters and which ones do you need to change and when?** A: Many online sources that sell RO systems. A search for the RO system itself will typically get you a list of a bunch of places that can also sell the filters. You can buy them thru Amazon in multiple versions. Individually, 1 year pack, 2 year pack, 3 year pack. In a year some of the filters are recommended to be replaced twice, some once, etc. And the "pack" comes with the right number of filters for that period of time. Stage 1 (FP15) is a 10" sediment filter replacement recommended 3-6 months though in our house we have a pre-filter for the whole house so we don't replace this one as often. Stage 2 (FG15) activated carbon filter replacement recommended every 3-6 months. Stage 3 (FC15) CTO carbon block filter replacement recommended every 3-6 months. These three are in the 10" vertical tubes and are relatively easy to change. Stage 4 (MC1) is the RO membrane itself. Recommendations on replacing this are every two years but vary. We have a pre & post particulate monitor to help us tell when it's losing its effectiveness as this is the most expensive component to replace. Multi-year filter packs will include an RO membrane but a single year pack typically will not. Bear that in mind when looking at cost of 2 year vs. 1 year packs. Stage 5 (FT15) another carbon filter but post RO. Recommended replacement annual. Stage 6 the Alkaline filter that actually puts minerals back into the water. This is recommended to be replaced every 3-6 months. In my experience you will begin to taste when this one needs replacement. This stage is the reason I bought this particular RO system and I like the taste it gives to the water. IMHO it will diminish over time and give you some indication when it needs to be changed. If you search in Amazon under something like iSpring Filter Pack **Q: what is the sie of the hole required (in the granite slab) for the faucet?** A: I think there is some confusion with the answers here. I think people who are stating holes over one inch are referrring to standard size holes that are factory or site drilled., and are already there. The faucet has a larger than 1/2" excusion that should cover a larger hole. By all means if you need to drill your own hole, only make it 1/2", because that is all that is required. **Q: is there a difference between this brand and other brands like tap water master? why is the price gap so dramatic** A: Since 2005, iSpring has brought the price of an average RO system down from $700 range. We bypass middlemen, sell direct online, cut advertising and live up with customers review by continuous improvements. We are doing what we want to do, that is, make clean water available and affordable to more people. We believe in long term value. So please let us know where we can improve, and write review to share your joy and experience.

Installation was simple and the instructions were very clear and easy to follow. The quality of everything with system is also very good, feels very durable and like it will last a very long time. The water coming out of this system seems very clean and tastes great! the water flow from the included faucet is good, faster than what my fridge water dispenser puts out. Overall I'm very satisfied with this purchase! Had a couple questions during and after installation that Robert at support was very helpful and super fast to get back to me. I don't really expect that type of customer support from the majority of companies anymore, but the response time and knowledge and helpfulness were really above what I've come to expect nowadays, very nice to see and made me more confident in the decision to go with this system. ## 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.ro/products/82522998-ispring-rcc7ak-bn-nsf-certified-75-gpd-alkaline-6-stage](https://www.desertcart.ro/products/82522998-ispring-rcc7ak-bn-nsf-certified-75-gpd-alkaline-6-stage) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-04*
