Style: 6-Stage with Alkaline Filter


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.

I have had two iSpring systems over the past 7 years; one at my previous residence (5-stage) and one at my current (6-stage). I've replaced a lot of filters over the years. We bought one originally because the water at my previous house was not very good. We would buy four 24-count packs of bottled water about once a week. We did some cost analysis and figured we were spending about $500 per year on bottled water and saw that the filter system was about half that price, and about a quarter the price each year after for replacement filters. We actually brought the old filter to the new house until the old house sold, since it was technically included in the sale. Overall, the taste of the water is excellent. It is honestly hard to drink my regular tap water at this point and we often will fill gallon bottles to have when we go on vacations. Adding the alkaline filter makes the water taste even better, so I would highly recommend spending the money to include the sixth stage. Installation is fairly straight forward and simple. I have had to drill a hole in the sink drain pipe in both houses. The most difficult part is attaching the faucet to the counter-top. It helps to have two people; one to hold the faucet in place and one to tighten the fitting below. I have only had two leaks in the last 7 years (neither were serious). One was a fitting on the fifth stage filter, but replacing the elbow joint fixed the issue. The second was that the faucet started to drip. The drip was very mild—like one drop every 5 minutes. The second leak is where I had to actually interact with iSpring. I emailed the company to see if I could purchase a new faucet. I figured I would need to buy a new one because the system was 3-years-old at that point. The next day I received a phone call from Sean at iSpring. He told me that while the warranty for the system had lapsed, there was still an active warranty for the faucet (I believe it was a 5 year warranty). He asked me where I wanted it shipped. This has been a great product. I honestly cannot recommend it enough. The water tastes excellent, the product is reliable, and the company supports the product. ... show more

    • Water tastes delicious, my ice is crystal clear
Style: 6-Stage with Alkaline Filter
My wife and noticed that the pans we use to boil vegetables or pasta had a lot of mineralization on it. So we tried to experiment where we used three different pots of water. One was straight tap water, one was water from the refrigerator which has a filter and one was from a Brita filter. All three tests came up with limescale which tells me that the water is highly mineralized. We began purchasing bottled water, and to me it made more sense to use our tap water and a reverse osmosis system, since that's what most of the bottled water vendors do anyway. We purchased the iSpring reverse osmosis system because it had good reviews and it was being sold by Amazon, so we didn't have to worry about returning it if it didn't work properly. I set up my system in a pretty unorthodox manner. I put a plastic tub next to the refrigerator, then used the refrigerator hose that brings water to the refrigerator and connected it to the reverse osmosis system... then for the cleaned water, I split it into two taps - one with faucet that I use to fill bottles of water up easily - the other tap went into the refrigerator and ice maker. There's quite a bit of runoff water with a reverse osmosis system, and I didn't want to waste that, so I set up a bucket next to the system to collect the waste water, and when it is full I use it to water my garden, or my bushes. Like I said in the title, my water tastes great, my ice is crystal clear, and we generally feel that this is a very eco-friendly alternative to buying tons of bottled water and plastic jugs. We use recycled 1 gallon wine jugs to hold water that we use for cooking or other things around the house, and then we bought little 12 oz bottles that we just fill up and put in the fridge so we can always have a nice cold water when we want it, free of plastics. ... show more

    • No more bottled water!

I purchased the iSpring RCC7AK 6-Stage RO filter out of necessity when I could not purchase a sufficient quantity of bottled water at the store due to the COVID-19 shortages. Before this, I drank only bottled water because my tap water is especially rusty and full of sediment due to old pipes in my neighborhood. The tap water also had a strong smell of chlorine, metallic taste and would smell funny if stored in the refrigerator for a few days. That is no longer the case! Now, thanks to this RO filter system, I get water from the faucet that is as good as, if not better, than the water I bought from the store. I figure I'm saving at least $25 a month in water costs, which will have the system pay for itself in way under a year. Plus, no more lugging gallons of water from the store or making unnecessary trips in search of water. The system is fairly easy to install, requiring only the most basic understanding of plumbing and hand tools, albeit it helps to be flexible to get under your sink. The instruction manual is helpful, and there are several videos on YouTube to walk you through the process. All I can really say is that there's a big difference between watching someone else do it and doing it yourself. In particular, the instructional videos make it seem easier than it is because they're not shimmying under a kitchen sink with three drain lines, multiple water hoses and electrical conduits for a disposal and dishwasher. I feel the one thing either missing from or not emphasized enough in the manual is that the storage tank can be stood upright or placed on its side. This was critical for me because the tank would not fit under my sink standing up, and I have a standard 36" cabinet under my sink. My drain setup may be most of the issue - you can see how complicated it is in the pictures. Of course, what little usable space I had under the sink is mostly gone, but that's a small price to pay for clean water. Another potential issue with the instructions is with how vague they are regarding the installation of the drain saddle. It is recommended that it be placed on a horizontal section of pipe to prevent the sound of dripping water, but that's about all it says. My suggestion is to put it on a horizontal section of pipe just past the P-trap, preferably with the hole pointing straight up. Not only does this eliminate the sound of dripping water, but this might also prevent your system from malfunctioning should you get a clog in your trap, and it's less likely to leak into your cabinets if the drain saddle doesn't seal perfectly. I may be wrong about this, but I also think the videos missed the part about cutting a 45 degree angle on the waste water tubing (black tubing) to prevent the line from being blocked if it is over-inserted in the drain pipe. The instructions also walk you through a system purge to clear the lines, tank and filters. I think a combined approach from the videos and manual worked best for me. As shown in one of the YouTube videos, I disconnected the line from the third stage filter to purge the first three stages separately from the rest of the system. Then, keeping the tank valve closed, I reconnected the system and purged the last three stages. This is especially important for the systems with the Alkalinity post-filter (Stage 5). I had to purge the last three sections for 30 minutes before the water stopped being cloudy from what I assume was excess minerals coming from the Alkalinity filter. After that, I opened the tank valve, let it fill once and drained it according to the instructions. As for the hardware, my main gripe is that not all the quick connects had pre-installed, color-coordinated clips. However, the box contained a bag of extra parts that allowed me to perform the installation. I'm not sure if this was an oversight or just the way it is supposed to be. There was some water in the RO canister when I opened it to install the RO membrane. I speculate that either my filter system had been returned (possibly explaining the "missing" clips) or that the system was pressure tested prior to leaving the factory. In any event, the purge process cleaned everything up. A few other minor gripes: The filter section could use some kind of handle to lift it and for holding it while tightening or loosening the filter canisters. Perhaps this is intentional to keep you from over-tightening the connections? Also, the mounting instructions seem like an afterthought. I really can't imagine anyone mounting the filter section under their counter. It is far easier to just slide it under your sink and rest in on the bottom of the first three stages or lay the system on its back. Also, I installed the faucet in an opening in my sink originally intended for a soap dispenser that I never used. I cannot imagine most people using the included mounting hardware for the faucet, so that seems like it should have been a separate option. If it's of any importance, the faucet that came with my system is brushed nickel, but my original hardware is chrome. The distinction isn't that noticeable and I don't mind it, but it might have been nice to have an option (if there was one, I was not aware of it). My system also came with a leak detector that can shut off the flow of water to the system if water starts to pool under the sink. My leak detector uses some kind of pulp material that absorbs water and expands to shut off the flow. It's very low-tech, but that may be a good thing. Some of the videos I saw showed systems with a battery-powered leak detector. Of course, batteries can wear out. Still, an option between the two might have been nice. I did not install the leak detector, so this is just an observation. Overall, I am very pleased with the system despite my concerns and observations. The system is simple and sturdy. The water is creates tastes great and looks crystal clear. My only regret is not having purchased it sooner. ... show more
