Water is purified by reverse osmosis nowadays. Nowadays, reverse osmosis purifies water. RO filtration also removes beneficial minerals. RO systems so far have added minerals. With the iSpring RCC7AK unit, you can achieve the best results. Take a look!

You should strongly consider using RCC7. RCC7AK, on the other hand, has a wonderful feature called water remineralization. In addition to making water healthier, it also enhances its flavor. Alkaline water tastes better than regular water when its pH is raised.

In addition to producing 75 gallons of clean water per day, RCC7AK can also produce electricity. There are six filtration stages in the system. How does water get wasted?

For every gallon of water, three gallons of water are required. This is the amount used on average. When measuring, it is also important to consider water pressure.

  • A cartridge filter is used in the system. This convenient plastic filter holder holds the cartridge filters. Where can the filters be changed?
  • Replacing the filters on the RCC7AK is not an easy task. You can replace filters from some systems with new ones, for example. Where do you find this option in RCC7AK?
  • You need to loosen the housing using the wrench that you have. You need to unscrew the filter cartridge by hand. Despite the spill, it isn’t dangerous. Installing the new filter may require lubricating the “O” ring. Secure the housing by tightening it up. Newbies may find it easier.


It is easy to install this filtration system. Before you begin, though, you should know the range of pressure. At pressures ranging from 40 to 80 pounds per square inch, the system is designed to function. It is also not a problem if your home’s pressure is not within that range.

  • You can purchase a permeate pump if your system does not have enough pressure. For high pressure, however, you will need a special regulator.
  • Installing the system takes less than an hour if you have some basic DIY skills. A plumber can also do it for you. A sink hole must be drilled. Drilling is not necessary for soap dispensers if holes are already there.
  • It is a good idea to read the user manual before beginning the installation.

iSpring RCC7AK Filter Effectiveness

The filter can block what contaminants? What kinds of contaminants can it block? Among the most common are fluoride, chlorine, arsenic, and sodium. The system will soften the water as well as make it safe for use in appliances around the house. These filtration systems will also extend the life of other units.

  • In addition to the RO membrane, there are six filtration stages. The first stage uses PP sediment filters to remove large particles. Lead and mercury are then removed with a carbon filter. Third stage removes chlorine effectively, while improving water taste and odor.
  • In the fourth stage, the RO membrane filters the water, so the water will be relatively clear. The RO filter will last longer.
  • Water reaches the tank five stages later, which takes about two hours to fill. Water pressure and quality play a major role. No contaminants are introduced. When needed, it is released. pH filters bring it all together. It is more mineral and alkaline.

Reverse osmosis removes minerals and good minerals. The alkalinity and taste of the water will decrease. Its pH value will decrease and become acidic. Drinking water can be made safe and clean by adding healthy minerals to it.

iSpring RCC7 vs iSpring RCC7AK

Some similarities exist between these two models. 99% of harmful contaminants are removed in both systems. In addition, both systems produce 75 GPD. In both systems, the waste to clean water ratio is 3:1. Even the filter life is the same in both systems.

The RCC7AK filter system has six stages. The Remineralization filter adds to RCC7. Water is balanced and all the essential minerals are restored. Nonetheless, both systems have a poor remineralization filter. The water won’t become alkaline, for example. As a result, a pH of almost 7 will be restored. Acidic pH levels will be neutralized. Even bacteria and viruses can be killed by UV light. That’s the RCC7AK-UV. Price is higher too.

iSpring’s 6-Step RCC7AK System

RO systems operate similarly in general. To begin with, the system connects to your cold water supply. When water reaches your faucet, it is filtered. In addition to the filter, the water is stored and filtered in a tank at the end. There is a remineralization feature on this unit that sets it apart from RCC7AK. The water is ionized and added with minerals from the stones. However, there is no direct health benefit, but it does enhance the taste of the water.

Contaminant Removal

99% of contaminants can be removed by the filter. A total of 1000 contaminants were removed, including arsenic, pesticides, viruses, bacteria, and protozoa. This also removes dirt, chloride, rust, and other “popular” particles. Compared to bottled water, the water you get is excellent. Additionally, 95% of fluoride is removed by the filter.

Water Wastage

There is a certain amount of water wasted by every system with a RO membrane. Nevertheless, the quality of the system will determine how much water it wastes during the process. Every gallon of water produced by this system is wasted. It’s still better than most systems currently in use. Water can be wasted up to 5 gallons per gallon in some systems. That’s too much. You’ll also pay more for water.

Filters for the RCC7AK by iSpring

iSpring’s RCC7AK filters are reviewed here. With these, you can effectively remove most bacteria and particles. Small and simple, these systems fit into most kitchens. High-quality filters make this unit the best. Quite long-lasting filters.

A refrigerator and an iSpring RCC7AK

iSpring can receive water from your fridge. You can use high-quality water while saving money. Any filtration system will work with iSpring. We recommend inline filters.

It is also easy to install. The quick-connect fittings make installation easy. Even a novice can install it. Furthermore, it is a long-term investment that is very durable.

Ratio of TDS rejections

Secondly, you should evaluate the rejection ratio of the Total Dissolved Solids. Compared to the previous model, this unit achieved a ratio of 90%, and that’s 5% higher.

What We Like

  • A 6-stage filtration system that eliminates 98% of contaminants.
  • Mineral water that tastes great.
  • Suitable for large and small families.
  • Easily installed by yourself.

What We Don’t Like

  • Water efficiency is lower than that of premium ROs.
  • This is a relatively low flow rate.

FAQs – Aquasana 3-Stage Max Flow Review 2023

Replaceable filters where to buy?

Filters are usually sold with RO systems online. Packages usually last one, two, or three years.

Filters: How Often Should They Be Changed?

It is important to filter. RO membranes (4th stage) last 3 years if replaced every three months after the third stage. As well as the sixth-stage filters. 5th-stage filters should be changed annually.

The Filter lasts for how long?

Up to 15 years can be expected from an undersink RO system. You must choose a quality system and install it properly. If the problem recurs, a new system may be required.

Aquasana leaks. Why?

Aquasana water filters have fallen victim to leaks allegedly caused by faulty locking tabs. Filtered water is sealed by these locking tabs as it passes through osmosis.


Online reviews highlight the affordability and ease of installation of the iSpring RCC7AK.

In general, remineralization and RCC7 are not significantly different in price.

Comparing the filters to competing systems, they advertise a relatively short life span. They also offer cheaper cartridges.

A TDS meter can be used to check the efficiency of filters before they are changed, rather than using the usage time. In reading the literature from iSpring, it is refreshing to see that they take negative reviews seriously and have upgraded components that may have previously caused problems as a result.

I highly recommend the iSpring RCC7AK reverse osmosis system because of its features, reputation, and quality.
