Review: If you can put a price on health, it's the cost of this unit. - REF; RCC7AK 6 STAGE RO SYSTEM: Firstly, I would like to say that the customer service at iSpring is exceptional - Francis to be specific. I had a very minor issue that did not scare me away from this product nor create any annoyance re. installation. Francis quickly contacted and helped rectify a very minor issue I had, following up with me to try and rectify the issue asap - thank you Francis! Packaging & instructions/fitting: The box arrived well packed and packed so well that I would not expect damage during transit. Each item was in its own box and had very little movement. The items came out of the box easily and had no damage. Well packed. The instructions for the assembly and fitment were very detailed. If self-fitting this unit, you probably have some kind of idea about what you are doing so you may not need to use the instructions as gospel, but they do provide a very well detailed and easy to follow assembly instruction. The flow diagram was welcomed too. A nice quick reference guide to hosing. This helped me more than the instructions - I find visual instruction easier than detailed description instruction. Whether you work in fluid engineering or fancy the DIY challenge, the instructions supplied will certainly allow you to install with ease. It took me about an hour to install and commission/leak check. The unit (although it looks rather large) fits very easily inside of my 900mm wide cupboard. It even allows for space around the filtration unit and the reservoir for placing filter spares etc. It certainly surprised me with how well the unit fits inside of my cupboard. I expected to assemble it, offer it up to the cupboard only to find it was too large to fit and then need to send it back… but I could fit two RCC7AK 6 Stage systems inside of my cupboard. Perhaps it opens scope to add further filters elements onto this system in the future… Filters are easy to change. This unit comes with a filter housing removal tool to provide leverage on the housing. Install the filtration system above the base of your unit to allow ease of filter change. There is a detailed commissioning instruction near the end of the instruction so please do follow this for the correct initial start-up procedure to purge the pre-osmosis filters (ensuring you do not put carbon deposits into the RO (reverse osmosis) membrane. Supplied parts: During assembly, I happened to think to myself 'a 90 elbow fitting would be perfect here'... they had thought of that and supplied multiple fittings! More than I needed. The length of piping was perfect. I used about half of what was provided - even with a drain line that extended far down the waste pipe into the next cupboard (install horizontal and away from the u-bend trap to eliminate a dripping noise and potential backing up of sink waste into the drain-line in the event of blockage). All parts supplied fitted my standard UK kitchen (15mm comp / 1/2" BSPP) but I did use some PTFE between the threads just to seal them as the thread form is NPT and my kitchen is BSP (thread angles are slightly different and therefore do not mate perfectly). I have had no leaks in the week I have had fitted. Taste/Testing: The taste is incredible. It tastes pure and clean. No tang or bitterness. It tastes purer than the purest bottled water I have tasted. I will now avoid drinking water that has not been through my RO system. Bottled water at a push! I have (glass) bottles stored in the fridge filled with my RO water. Bottled water is nice... but iSpring RO water is second to none. I agree with another review here that I fill my bottle with this water and take it everywhere I go. See the images for the testing. I believe that these images speak for themselves. Obviously, the RO water cannot be TDS free due to the remineralisation process but down to 47PPM from 435PPM is an incredible job and there is a clear difference in the ‘clean’ taste even between RO water and bottled water. This is evidence enough that the water is truly forced through the osmosis filter. Alkalinity of this water is slightly higher (TAP is 7.66pH, BOTTLED is 8.70pH *Sometimes artificially raised using Bicarbonate of soda, RCC7AK RO is 9.72pH). Yes, I did calibrate my pH meter prior to use! I am yet to perform some detailed research into the difference a higher pH water provides but brief research suggests that it is easier for the body to consume. I will take higher pH being better for the body at face value at this point for this review. Overview: I would suggest that this unit is installed in every home for the sake of reducing the number of chemicals that are consumed through water. At the very least, bottled water should be consumed. Avoid tap water! For the small cost (yes, the cost of this unit is relatively low) this unit is 100% worth purchasing. Fitting is easy, it comes with a nice outlet for the water, water tastes incredible, and the customer service is outstanding. Every home should be fitting one of these units. And whilst you are at it... consider stopping using fluoride containing products such as toothpaste and mouthwash. Use fluoride-free alternatives. I have personally noticed positive differences with regard to dental/mental health. BUY the iSpring RCC7AK! – I was not provided any incentive to leave this review. All opinions are from my experience of using this product!
Review: Brilliant! - 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!

## 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.

## 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.

Thank you,

### ⭐⭐⭐⭐⭐ A great product. RO is the way to better sustainability.
*by C***Y on 28 June 2025*

I have had one before therefore for our new property it was the obvious choice. Very robust, easy to assemble with clear instructions. Very well made. The water now is safe and tastes great especially with the additional alkaline add back cartridge. The tank is big so there is always water available for drinking and cooking, rinsing food etc. Why buy and carry litres of bottled water. RO is the way to better sustainability.
