iSpring RCC7 RO System Review | iWater Purification

While clean water is an essential need, not every homeowner can vouch for the quality of water in their homes. The municipal supplies to our taps and wells are frequently contaminated with impurities, either as a result of inadequate treatment or because of unclean transport facilities. Thus the need for your own water filtration system is not only desirable but necessary. And while there are many options to choose from, experience shows that the reverse osmosis (RO) system is one of the best solutions available when it comes to getting the best out of your drinking water. And on top of the list of the top-notch RO filter systems currently in the market is the iSpring RCC7 High Capacity Under Sink System and Ultimate Softener.

Gold sealed and certified by WQA, the iSpring RCC7 is a filter system well known for its high efficiency and superior performance. It can remove up to 99% contaminants in water and comes with a capacity of 75 GDP which is quite a lot for drinking water filter system. To crown in all, the iSpring RCC7 is one of the budget choices we included on our list of top RO water filter systems in the market.

Special features

There are certain features that make the iSpring RCC7 a water filter system in its own class. Since you are most likely to buy the product online, it will help to know about these features in order to prevent any surprises.

5 Filter Stages

The presence of impurities in water doesn’t only affect the colour but also the quality. The iSpring RCC7 comes with a 5 stage filter system that is able to achieve up to 98% removal of contaminants in your drinking water. This arrangement ensures that even the tiniest toxic micro-organism does not escape all the levels of the filtration system. Thus the resulting drinking water flowing from the system is clear and contains the least amount of pollutants.

Additionally, the filter system is strong and reliable and doesn’t get clogged as water flows through it.

Low water efficiency factor

The low efficiency factor of the iSpring RCC7 is one of the features that make it highly desirable. Compared to the 6 gallons to 1 gallon of water specification for most filter systems, the iSpring RCC7 only requires two gallons to produce one gallon of clean drinking water.  And it has the capacity to provide up to 75 gallons of purified water per day (GDP) without any reduction in the quality or taste of the water. It may interest you to know that the capacity of many filter systems in the same fold as the iSpring RCC7 does not exceed 50GDP.

So with the iSpring RCC7 filtration system, you can be rest assured that you will always have a full tank of pure water but of course this also depends on the size of your family.

Easy Installation

The iSpring RCC7 can be easily installed under your kitchen sink without any need for additional fittings or space and you don’t need to be a pro to be able to be able to do it. All you need is patience and careful adherence to the step-by-step instructions contained in the instruction manual which is simplified with tutorial video to make the whole process a breeze. Even if you don’t have any skill set, you should be able to set up the whole thing in an hour.

However, in order to mount the dispensing faucet, you need a hole in your sink which may not be there. In such case, you need to make the hole before installing the unit. And if you think it’s not something you can do, then you should get a good plumber around.
