iSpring RCC7AK Reverse Osmosis System Review Upadted

You may experience the safe, clean and healthier water by using the reverse osmosis water filtration. But you have to drink the bland water because, during filtration, systems remove the pollutants and harmful minerals and even the taste from water that you may not prefer. But now even after the filtration process, you can enjoy the taste of natural water with balanced minerals. In this “iSpring RCC7AK Review” you will explore how it is actually helping in this problem.

iSpring RCC7AK Review

iSpring RCC7AK ReviewiSpring RCC7Ak is the highly praised variation of the iSpring RCC7.

iSpring RCC7AK comes with the addition of remineralization filter. This filter stage restocks the water with the minerals that provide flavor. It adds all the beneficial minerals back into the purified water and raises the pH to be more alkaline.

It helps you to avoid drinking acidic water. It’s time to experience the safe, clean and fresher tasting mineral water that everyone prefers.

iSpring RCC7AK is a higher capacity system that processed more water. It produces 75 Gallons per day as opposed to usual 50 Gallons per day. The higher capacity allows you to get a full tank for longer and faster. Now you don’t need to worry about running out of the water.

You don’t need to replace or to do maintenance of components for many years to come. Their premium quality ensures higher reliability.

iSpring wastes 3 gallons of water to produce a gallon of purified water. This waste depends on the feed water pressure.

Anyone can install it within 1 hour with the basic DIY skills. If you don’t have skills you can still do it. The company has a video on youtube to avoid the troubles that the customer may face or you can have the help of the plumber.

Filtration system

iSpring RCC7Ak is recommended as an under sink mounted water filter and water softener. It removes 99% of the 1,000 contaminants including calcium, sodium viruses, bacteria and many more.

This filtration system makes your ice cubes more crystal clear. You can enjoy the fresher and acidic free tea and coffee. Feel the joy of water better than bottled water.

unlike iSpring RCC7, this model is the 6-Stage filtration system.

Let’s explore how it is better to provide the purified water with a natural taste.

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% of fluoride. This stage says goodbye to all these particles.  Ro membrane rated at 0.0001 microns that means this stage does not only anything to go through it except the pure water. And welcome healthier 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 to be more alkaline and improves the taste too.

Water Efficiency

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

iSpring RCC7AK water wastage depends on the feed water pressure and temperature. While normally, it requires to waste 3 gallons to produce a gallon of purified water. This ratio is relatively competitive, above average and better enough from a lot of other RO water systems that come in its category.

Highlighted Features

Transparent housing

You can visually examine the process of removing the contaminants from water and the sediment filter. With this feature, you will easily recognize the time for filter change instead of facing any problem.

Maximum Efficiency

It has 5-micron GAC & CTO filters that loose carbons 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

Ease of installation

Most of us prefer the self-installation of the osmosis systems. Considering this iSpring invested in video productions to provide us the better resources needed to have successful installation and maintenance. Its push to connect fittings and color-coordinated tubings make the installation process simpler and allow to prevent leaking. 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.

Final thoughts

This is one of the best Budget choice you can avail.

Most of the user called it the best investment as they are getting a remineralization stage by spending a few more dollars that most people prefer.

iSpring draw an image of the short life of the filters as compared to other available in the market but this span of life is balanced by the lower cost of iSpring cartridge versus the competition.

The best concern about iSpring is that they consider their customers feedback. As the well-known seller in America, they review negative feedback and responded to them by upgrading components that are causing problems to their customers in the past.
