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.

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.
