iSpring RCC7AK Reverse Osmosis Water Filtering System Review


Best Price

If there is one brand that you can trust as much as APEC, it would probably be iSpring. They create USA-manufactured products that have a quality that you can trust in. The RCC7AK is just another one of iSpring’s wonderful line of reverse osmosis systems.

This model uses a new type of membrane for better filtering and made several changes to the brand’s traditional design for more compact storage and easy installation. However, while being easy to install and out of the way are some coveted traits in reverse osmosis filtering systems, how does the RCC7AK stack up when it comes to actually filtering the water?


The iSpring RCC7AK is a six stage filtration system that not only puts your water through three carbon filtering stages, a membrane stage, an a polishing stage, but it also has a built-in alkaline remineralization stage in which the water has its pH balanced and adds back in minerals like calcium, magnesium, sodium, and potassium that were removed during the filtering process.

While you might not care so much about minerals being added back into the water, it is not just about the health benefits, but these minerals actually give water that coveted refreshing taste. It is the reason we enjoy the taste of bottled water so much more.

This added remineralization stage is a major boon, but even if the model didn’t have it, you would still be treated to water that has had 99 percent of contaminates including chlorine and fluoride removed so it is perfectly pure for drinking. It performs so well that it is able to proudly display the WQA’s Gold Seal certification that assures top quality.

While the actual filtration system itself isn’t particularly showy, it is relatively easy to install and fits easily in most kitchen cabinets. However, the part you do see, the faucet, is a treasure to look at. Designed in the European style using brushed nickel, it is a faucet that looks beautiful and doesn’t show any ugly smudge marks like you get with polished chrome.

In terms of actual water processing, the RCC7AK performs about average. It does have a pretty high capacity of being able to produce 75 gallons of pure water per day, but as reverse osmosis filtration systems go, that capacity is not that far about the average.

Potential Issues

There is one potential complaint that several people have had with this system though. Apparently, the automatic shut off valve has a habit of occasionally breaking for some people. However, with a one year warranty, if it does break shortly after your purchase, you can at least get it replaced by the manufacturer.

If you are looking for an affordable reverse osmosis system that also creates alkaline water and adds back in essential minerals, then there are much worse choices than the iSpring RCC7AK. It performs admirably and rather quickly for a system that also does alkaline water, which takes it from being a completely average reverse osmosis filtration system and making it an above average one.
