iSpring RCC7AK Reverse Osmosis System Review

The iSpring RCC7AK Reverse Osmosis System Review”  is a must-read for anyone preparing to buy an RO. We cover all the features, benefits, and drawbacks this product has to offer in our breakdown. You’ll also find that we created a list of pros and cons for you to consider before making your final decision if the iSpring RCC7AK is the right RO system for you.

If you are reading this review, you probably already know that reverse osmosis systems work by forcing water through a membrane that only lets the purest of H20 pass through. But of course, not all systems are the same. So. have you ever considered the quality of the water an RO delivers?

iSpring RCC7AK Reverse Osmosis System

Reverse osmosis treatment systems can of course remove all the nasty toxins. But unfortunately, pure H20, deprived of all minerals has no taste at all, but what if I told you there was a way to preserve that healthy mineral water taste while ensuring safety at the same time?

The iSpring RCC7Ak system does just this! With an innovative design, it removes pollutants such as chlorine and heavy metals without sacrificing minerals like calcium and magnesium. Not only are these substances dangerous for our health—they also alter flavor so now we don’t need to sacrifice anything when choosing cleaner water over bottled drinks – because, with the iSpring filtration process, natural tasting mineral water is always available.

iSpring RCC7AK

1. iSpring RCC7AK

Certified to NSF/ANSI 58.

  • The iSpring RCC7Ak is a great value for money under sink mounted water filter with the added bonus of being a water softener too.
  • Th RCC7AK has 5-micron GAC & CTO filters that release carbon which are better at confining contaminants and removing micro-organism.

iSpring RCC7Ak is the highly anticipated, improved variation of the popular iSpring RCC7 RO System.

The main improvement is that the iSpring RCC7AK comes with the addition of a remineralization filter. This filter stage replenishes the water with essential minerals that also provide flavor. It adds all the beneficial minerals back into the purified water and raises the pH to be more alkaline, which some argue is more beneficial to humans than neutral Ph water.

Even if you disagree with the reports about drinking Alkaline water, it can not be disputed that is it better than drinking acidic water. It’s time to experience the safe, clean, and fresher tasting mineral water that everyone prefers. You won’t regret it!

iSpring RCC7AK is a higher capacity system that can filter and process more clean water than other systems in the same price range. It can produce 75 Gallons per day whereas similar units only produce 50 Gallons per day. The higher capacity is great for slightly larger households. Now you don’t need to worry about running out of water as you may do with smaller systems.

You don’t need to do any more work on your car for years. The high-quality components are guaranteed, so you can rest easy!

All Reverse Osmosis systems will have a certain level of water waste, and the iSpring wastes 3 gallons of water to produce a gallon of purified water which is not the highest of efficiency, but it is still an efficient system for the price. This waste does depend on the feed water pressure.

How Easy Is It to Install the iSpring RCC7AK?

Anyone can install it within 1 hour with basic DIY skills. If you don’t have previous plumbing skills you can still do it. You may just want to watch the instructional video a few times before starting the DIY install

We found this user video on youtube which is a real help and will keep you from the troubles that some customers may face.

Is It a a Good Value Filtration System?

The iSpring RCC7Ak is a great value for money under sink mounted water filter with the added bonus of being a water softener too. It removes 99% of over 1,000 potential contaminants including chlorine, fluoride, barium, salmonella, calcium, sodium, viruses, bacteria, and many more.

Why drink water when you can enjoy it? This filtered system is great for making ice cubes that won’t taste stay, and tea or coffee that will be the best you have ever had.

Improving on the old iSpring RCC7, this model has a 6-Stage filtration system.

Unsure what that means to you, then let’s explore how the iSpring RCC7AK provides purified water with a natural taste, stage-by-stage.

Is It a a Good Value Filtration System

Stage 1: A polypropylene (PP) pre-filters eliminates all the dust, sediments, and other microparticles. That filter comes with transparent housing from which you can examine the process and always know the time for filter replacement.

Stage 2: After removing macroparticles from water 5-micron GAC removes the chlorine, taste, and odors from water. The process of this stage assists stage-3 and 4 to work more efficiently. That’s why they are the last longer that saves your money for a long time.

Stage-3:  A 5-micron carbon block filter wipes out all the chloramines, VOCs, and all the injurious chemicals from water.

Stage-4: Your water has 96% of lead, 98% of waterborne pathogens, and 94% fluoride removed. This stage says goodbye to all these particles. This is a fine Ro membrane rated at 0.0001 microns means this stage does not only anything to go through it except the pure water. 

Stage-5: GAC post filter removes the odors and even the natural taste of water. At this stage water becomes more acidic but enough safe and clean to drink.

Stage-6: All the minerals that were lost during the purification process like calcium, magnesium, and potassium are added back again into the water. This stage makes the water become more alkaline and improves the taste too.

Water Efficiency

Water Efficiency

Systems that waste water up to 3-4 gallons are considered above average efficient systems.

iSpring RCC7AK water wastage ratio will, as with all RO systems depend on the feed water pressure and temperature. As a manufacturer’s guide, the RCC7AK normally requires a waste of 3 gallons to produce a gallon of purified water. This ratio is relatively competitive, even above average, and more efficient then many other RO water systems in the same price and quality range.

Highlighted Features

Transparent Housing

Having an easy to see visual transparent housing is a great little feature of the RCC7AK filtration system, It means that you can visually examine the filters, and see when the sediment filter is getting full of contaminants.  With this feature, you will easily recognize the time for filter change instead of facing any problem of guessing and perhaps changing your filter too often, or even worse, not changing your filters regularly enough

Maximum Efficiency

Th RCC7AK has 5-micron GAC & CTO filters that release carbon which are better at confining contaminants and removing micro-organism. It leaves only smaller ones to the CTO carbon block filter that permits the Ro membrane and CTO filter to work at their maximum efficiency and last longer.

Maximum Efficiency

Ease of Installation

Most of us prefer the self-installation of the osmosis systems because this saves a lot of money on paying a plumber.

And thankfully this system is a real sinch to install, Its push to connect fittings and color-coordinated tubings make the installation process simpler and if instructions are followed will prevent leaking. As an added security though, a water leakage alarm is also included in the kit.
The systems can easily fit under the standard kitchen sink and include all the required parts for installation.
