iSpring RCC7AK Review

iSpring RCC7AK ReviewThe iSpring RCC7AK is one of the best reverse osmosis systems elections currently available in the water filtration industry. It is averagely priced but worth far more then what you will end up spending on it. All in all, this system is worth far more than it costs and will last you for years to come if you maintain it properly.


This RO system offers a six stage filtration process that will effectively rid your water supply of as much as 99% of more than 1,000 different contaminants it may be riddled for. More specifically, it will eliminate 98% of the lead in your water and 99% of the Arsenic, Asbestos, bacteria, Calcium, Chlorine, Fluoride, Giardia, hormones, Sodium, and viruses that may be in your water.

One of the stages in the iSpring RCC7AK six-step process is the remineralization phase. Many Reverse Osmosis water filtration systems feature this step in order to reintroduce healthy minerals that were stripped away during the filtration process—like Calcium and Magnesium—and to restore a natural pH to your drinking water. Not only will this step improve the quality of your water, but it also neutralizes the taste so you get crisp and delicious water you will look forward to drinking.

The system also utilizes 5-micron CTO and GAC filters to ensure it effectively and efficiently catches any contaminants and microorganisms in your water supply. More specifically, the GAC filter is in place to trap larger water contaminants and the CTO filter traps the smaller contaminants—this helps increase the life of the system’s filters, so filter changes won’t be required often.

One of the most popular features offered by this system is the easy to view housing it comes with. This will allow you to easily take a look at your sediment filter and the contaminants that have been stripped from your water supply. This feature makes it easy to keep track of filter changes, so you know when to go ahead and order the replacement filter. Overall, this iSpring RO system is able to filter up to 75 gallons of water a day, making it an excellent option for larger families!

Filtration Process

The iSpring RCC7AK reverse osmosis system uses six different stages to deliver clean and delicious drinking water, lets take a look at the processes of each stage.

Stages 1-3: Prefiltration

The first three stages of the filtration process feature 3 different pre-filters. This 3-step prefiltration process removes the solid contaminants from the water supply before your water reaches the RO membrane. This helps extend the life of your RO membrane, thus increasing the life of the system.

The first pre-filter utilized by the system is the sediment filter, which removes debris, sediment, and larger contaminants in your water supply. The second pre-filter is the GAC filter (Carbon KDF) and it removes the larger contaminants and microorganisms in your water.

Last but not least, is the CTO (Carbon block) filter the rids your water of the small contaminants still left as well as chemicals—such as chlorine and chloramines—that will negatively impact the system’s RO membrane.

Stage 4: Reverse Osmosis Membrane

Once your water has been filtered by the three prefilters we discussed above, it is finally ready to go through the RO membrane. This is the most important part of the system and is what makes reverse osmosis filtration systems truly stand apart from other water filtration techniques. Once the water has been stripped from solid contaminants and certain harmful chemicals, the RO membrane can then remove contaminants as small as 0.0001 microns. The RO membrane is the reason this system can remove 98%-99% of 1,000 different harmful contaminants.

Stage 5: Water Quality Improvement

The 5th stage of this iSpring RO system is where most standard RO systems tend to stop. Here the water is stripped of all minerals, including the good ones. This stage utilizes and FT15 carbon filter to remove the unpopular chlorinated taste, unwanted odor, improve the quality of your water supply.

Stage 6: Remineralization

The sixth, and final, stage of this system is known as the Remineralization process. Here the system employs the use of an alkaline remineralization filter in order to put the healthy minerals that were stripped away during the previous stages back into your water. This allows the system to deliver great tasting water with a balanced pH.

Material and Installation

This system is constructed with high-quality materials that are built to last you year after year if you properly maintain the system. The faucet that comes with its purchase is lead free, however, it is important to note that some parts of the system do contain PVC. The system’s housing is also see-through, so you can easily check on your filters it as needed. This is also an undersink RO system that is easy to install and designed to be leak proof.

Pros and Cons


• Easy to install
• Great price
• Offers Remineralization
• Access to support team


• Contains PVC


All in all, this is a quality RO system that uses six different stages to deliver drinking water that is safe to drink without sacrificing taste. It is available at a great price and is easy to maintain—so you can have peace of mind knowing you are drinking good-quality water.
