iSpring RCC7AK 6-Stage Reverse Osmosis System w/ Alkaline Filter, 75 GPD, NSF Certified
About this item
- 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 PFAS, 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.

One of the best DYI projects I've done!. Mounted unit in basement below the kitchen. John Guest fittings are phenomenal! But most of all, my wife, who will NOT drink city tap water, loves the "flavor"! We have it connected to our frig and even our ice is crystal clear! No more chasing after bottled water or bags if ice!

Like the headline says, I was quoted $3k for a RO system at Culligan. My wife has Menieres disease so we need to get all the sodium we can out of our water as she drinks over a gallon a day. Using the TDS meter i bought here on Amazon for $15, our water was measuring around 650ppm before i installed the iSpring, so we had a long ways to go! After the system was installed, we are down between 20-50ppm !!! Now we can stop buying all that $$$ bottle water for my wife!
I installed the system in my basement where my hose splits off the plumbing to go to our refrigerator. We just had new granite installed and didn't have a RO facuet hole, so we just ran it to the fridge only. I mounted the 6 filters to the basement wall and installed a rack to hold the pressure tank. It took maybe 30min to drill into the concrete and get everything hung and assembled. Very easy to install.
The reason for the 4 stars on instruction quality is there is a typo when it comes to the part about installing the RO cartridge. It tells you to remove the WHITE hose before taking the RO canister cap off...the hose there is actually RED. Luckily they have visuals to show the correct color, but it could throw some people for a loop.
The reason for the 4 stars on the install is that i had a few of the quick connects pop off the filter canisters when i pressurized the system. For some reason they didn't install the quick connect locking clips where the hoses go into the filter canisters. Fortunately they include a ton of spare parts, particularly clips. So i went through the entire system and installed a locking clip at every connection and that solved the problem.
When flushing out the first 3 filters, i went through approximately 10 gallons of water before it finally ran clear. It felt it like was never going to end, but it finally did! Once i hooked up the remaining 3 filters i only had to run about another gallon through until all 6 filters were producing clear water. You will have to scrap another 2-3 gallons when your instructed to fill the pressure tank with water and discard all of it after the first emptying of it. I did all of the flushing offline of my fridge using the faucet they provided. Once everything was good to go, i disconnected their faucet and hooked up the line to my fridge. ****Remember to either discard your fridge filter or purchase a bypass like i had to for my Frigidaire***

we would definitely recommend this product. here are few things that I have to figure out. check your water pressure if it is below 40 psi the you would need the same filter system but with a pump which it I think $50 more if presure is more then 70 or 80 psi then you will need a presure regulator to bring it down below. our water presure is 60 psi so we did not need anything else. we do not have a water softner on to the cold sink faucet and water in our area is very hard but this filter system worked well the only down side will be that we have to change filters more frequently. installation was a breeze. I had few questions so called the customer service left a voice mail and they returned my call the next day and were very helpful. tip: check the system once every few days for leaks as you can see in picture I had a leak which I have to figure out why

This was my first RO system. I did a lot of research and found that this brand (ispring) and model offered the best value, options and best reviews. It was easy to install and runs great. I love the fact that I have not bought one case of bottled water since I installed it on 9/5/2017. So far so good and very happy with the purchase, definitely will buy this brand again for my next house. Do yourself a favor and always go for the bigger model, I have two people in my household and I bought a 75GPD model and it has been great.

Upon research seeing great reviews on Home Depot - I decided to purchase this LittleWell 6-Stage 75 GPD Reverse Osmosis Alkaline Mineral Water Filter with Brushed Nickel Faucet and Clear Housing for my household. I have had this system for almost two months now. The installation was okay, it took me roughly two hours and a half to install. The instructions and video were a little off but I managed to figure it out. What I like about this system is there is pH in the water. Originally measured pH at 8 after one week. But now, averages out to be 7.5 pH. Hopefully in a few months, the pH will still be relatively high. Overall - A great system for drinking at home. This system is very convenient as you have drinkable water at home! You do not have to go to the store and refill water.

We have been buying bottled water for drinking because our water here tasted wired and has lots of calcium. It’s very hard water we have in our city. I’m very happy of the quality of water I get out of it. Plus I’ve saved a lot of money. I think it’s the best investment so far.

Customer service is unbeatable. Completely Satisfied with the product. Thank you

First the pros... water tastes great. City water tested at 227 ppm which this system brought down to 20 ppm. The bottled water reading with the same tester came out 21 ppm. So it's better or very close to bottled water. The set-up was easy and straight forward. It took me two hours but that's because of a leak. Details in the cons. the stainless steel faucet is of good quality and matches well with my kitchen faucet. The reservoir tank is huge and water pressure coming out of the faucet is great. I researched tons of RO systems before deciding on this one because I knew my family can't handle lower water pressure and they would grab the bottled water instead. So I was very happy to see nice water stream coming out the faucet when tank was engaged. Cons: The reservior is huge. It took up lot of space from my under the sink cabinet. The tank and system had to be placed on opposite sides to fit . I bought the system brand new from lowes, however the RO capsule had water in it when I opened it to put in the membrane. The o-rings on the carbon filter and sediment filter were damaged and they leaked profusely when I tried to flush the system. Seems lowe's sent me a customer return. It is fine after I replaced the o-rings. Not bothering to exchange since I have installed it already. Overall I am happy with the purchase.

We bought this because we have really hard municipal water and with our third baby on the way wanted to make sure we had filtered water not just for bottles but for cooking, tea, coffee, etc.
This system was affordable, we had a plumber install and it was fairly easy to change the filters (there is a thorough how to video online that boosted my confidence). The connections are "quick connect" so you don't really need extra tools. A strap wrench is REALLY helpful for filter change outs, but also useful for other stuff around the house - so worth the investment.
Suggestions - write the date you need to change each filter ON THE FILTER with a sharpie and make a calendar note - they vary in replacement frequency. It'd be awesome if iSpring put the avg. filter life range on the filters.
There is a 7-stage model with UV filtration, but it requires power under your sink - so check that first before you but and have a plumber at your house :)
For service - Nick on their customer service team was really helpful, he answered my questions quickly!

We recently bought a house in Florida that had well water. The well had an outside salt filtration system, but it still did not taste good, and it smelled like sulphur. I love water, but I did not want to buy bottled water because I don't like the taste of it. I checked into the osmosis system after my vet told me about them. I chose the ISPRING 6-stage system, and I am very pleased with it. No more smell, and it tastes great. One reason I chose this one is because our hardware in our kitchen is brushed nickel, and ISPRING systems come with the brushed nickel faucet. Otherwise, I would have had to buy a separate faucet that cost around $40. One strange thing happened. We have to use less coffee to make coffee. It taste a lot stronger with the osmosis water. So, we are saving money on coffee, and we drink a lot of coffee. One bad thing about the system is it is rather confusing putting it together, but probably all the brands are similar installing them. I totally recommend the installer watch the video ISpring has on YouTube WHILE doing the installation. https://www.youtube.com/watch?v=sDhC9XMKLPA One thing to be aware of is tightening the top down on the big water tank. My husband was afraid of over-tightening it . A few days later after installation I noticed a little water in the cabinet, but there was no harm because we had put a tray under the tank. My husband tightened it a little more, and everything was OK. Keep an eye on that after you install it to make sure it is tightened enough but over-tighten it. We separated our system and put the big tank in the cabinet next to the sink cabinet. That gave us more room under the sink. It was simple to do, just drill a large enough hole at the top of the cabinet to fit the water tube through. We also bought one of the hose kits to connect to the refrigerator water line. Now, we don't have to buy anyone filters for the refrigerator because the water is already completely clean by the time it gets there.

Where do I get replacement filters and which ones do you need to change and when?
For this Alkaline Reverse Osmosis Water Filtration System RCC7AK, it is recommended to replace: Why do Reverse Osmosis water systems waste water?To start with, let's make it clear: ALL Reverse Osmosis units produce wastewater. With the modern technique, the waster water ratio can be reduced but not eliminated. Here is how the RO system works. The RO water system will split the water stream into two flows; one is purified water, and another is wastewater. There is a flow restrictor on the wastewater line, which will slow down the water flow. Hence, it will create enough water pressure to force the H2O to pass through the semipermeable membrane to remove dissolved solids. Is there a difference between this iSpring brand and other brands? Why is the price gap so dramatic?Since 2005, iSpring has brought an average Reverse Osmosis filter price down from the $700 range. We bypass middlemen, sell directly online, cut advertising and live up with customer reviews by continuous improvements. We are doing what we want to do: make clean water available and affordable to more people. We believe in long-term value. I followed the instructions and my water is coming out cloudy. What can I do to correct this?The water is cloudy for the first gallon. Please follow the instructions to flush the Reverse Osmosis water filtration system until the water turns clear. If you followed the manual and it's still cloudy, please do not hesitate to contact us at (678) 261-7611 M-F 9-5 EST. Do the filers of RO filter retain / put back fluoride in the water after filtration?This Reverse Osmosis filtration system will remove fluoride and does not put it back into the filtered water. How does the alkaline filter work? It says it \"gives back\" minerals such as calcium, but my water has no calcium to begin (already softened).The Reverse Osmosis drinking water filter system removes over 1,000 contaminants from the water, including some healthy minerals. Then the final stage, Alkaline Filter, contains calcite (calcium carbonate), mineral stones, and Corosex (magnesium oxide), which will add calcium and magnesium to the water (30-60 mg/l is added). What should I do with the under sink reverse osmosis system when going out of town?When you leave for an extended period, you will want to shut off the water supply to the RO water purifier and empty the tank. To do this, close the knob on the feed water adapter, and open the faucet until it stops running. This will signify that the tank is empty. If you are gone for more than a week, you will also want to remove the RO membrane and store it in a damp Ziploc bag in the refrigerator. What if there is zero output water from the RO faucet
1) The water supply is closed. Open the water supply to the domestic RO filter system so the valve aligns with the red tubing. When installing this Reverse Osmosis water purifier, should the water source come through the Reverse Osmosis machine or directly from the raw water source?When installing a Reverse Osmosis water filter under sink where the water source is very hard, it is always recommended to install this unit after the water softener to prolong the membrane's life. So the best thing to do before installation is to get your water tested. You can read how to test your water here. If you do not have a water softener, you can simply install the RO machine directly to your raw water source. Although it may reduce the life of the membrane, it will still work. Can I install a water filtration system myself?Yes, a little basic plumbing knowledge is needed. The Reverse Osmosis drinking water system is designed for do-it-yourself installation. All necessary parts for installation are included, backed by clear, well-organized written instructions, instructional videos, and access to iSpring unparalleled technical support. What is the micron rating or smallest particles it removes? I'm concerned about microplastics that can be 1.0 micron.The membrane of this RO filtration system is 0.0001 micron, small enough to filter out most microplastics, but the system is not designed to disinfect your water or treat it for microorganisms. If your water contains microplastics or other microorganisms, we recommend treating this issue directly at the source instead before using any water filters. Or you can choose using RCC7AK-UV instead, which includes the Ultraviolet Filter that can treat unreliable water sources like lakes and streams. Why do I need to use a pressure tank?The expansion tank provides water pressure to your faucet. Traditional under sink RO water filtration systems usually need a tank to store pressurized water to meet the immediate water needs when you turn on the faucet. Secondly, the storage tank will also help with the system's operation. The RO tank will keep the pressure for the reverse osmosis system and automatically turn on / off the system by monitoring the waterline pressure. Why every fitting leak after installation?You have to push the tubing with a fair amount of force to get it to sit all the way. Usually, you have to insert the tubing about 1/2" into the push-in fitting. Secure it with the clip. If the leaking issue is still unfixed, please do not hesitate to contact us at (678) 261-7611 M-F 9-5 EST. Can this filter be installed on my refrigerator without the faucet?Yes, absolutely. The Reverse Osmosis water purification system can be used without the faucet. Where is this system made?The RO filtration machines without a pump are made in Taiwan, machines with pump are made in China. How much water can this system produce per day?This under sink RO system can filter up to 75 gallons per day. The storage tank can hold 3.2 gallons. If you use more than 3.2 gallons at one time, the water flow will be slowed down, but it can still come out. How many times does this under sink system need to be flushed before it's ready to drink from?3 times. The first flush is after installing the first 3 stages (the Active Carbon needs to be flushed first to avoid large particles going to the RO membrane) until the water is clean. The 2nd flush is after the RO membrane installation, which will get rid of the protector in the membrane and others for at least 15 mins apart from the tank. The 3rd flush is after the tank has been filled up completely. It will take 1.5 to 2.5 hours, depending on your water condition. After the tank is full, open the faucet and drain the tank completely. Is it BPA-free?Yes! All our products are BPA-free. Please don't hesitate to let us know if you have additional questions. Stay safe! Should I turn this Reverse Osmosis system for the kitchen sink off at night?No, this under sink Reverse Osmosis filter will shut off automatically once the storage tank is full. Does it remove PCBs?Yes, the reverse osmosis membrane removes 97% of PCBs. Can this residential RO water system be hooked up to an existing faucet rather than the one that comes with it?We strongly suggest using the included RO faucet but if your existing faucet can accommodate a 1/4" quick connect (push-in) fittings, this is possible. Please note that the flow may not be as strong if your existing faucet has a wide spout. How long is the faucet line?You will receive a 5 feet tubing for installing the faucet. Can this RO filtration be used for instant both hot and cold water?As long as the water for the instant heater is filtered before it gets heated, it won't be a problem. What we want to avoid is putting the hot water directly into the RO membrane. Can this RO water machine reduce mercury?For mercury specifically this RO system water purifier has a rejection rate of 96-98%. How do I make my reverse osmosis water alkaline?The reverse osmosis filtration system removes over 1,000 contaminants from the water, which includes some healthy minerals. You can purchase iSpring RCC7AK to make your RO water alkaline. The final stage of RCC7AK, Alkaline Filter, contains calcite (calcium carbonate), mineral balls and Corosex (magnesium oxide), which will add calcium and magnesium to the water (30-60 mg/l is added). Is the reverse osmosis water filter system NSF Certified?The innovative RO system under sink RCC7AK is certified to NSF/ANSI 58 for TDS reduction (58 for reverse osmosis). |
