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.
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.
