The iSpring RCC7AK water filtration system uses a comprehensive filtration process to provide high-quality drinking water. The system consists of three pre-filters, including a PP sediment filter, a Carbon KDF (GAC) filter, and a Carbon block (CTO) filter. These filters remove large contaminants and protect the RO membrane from harmful chemicals like chlorine and chloramines.

The Reverse Osmosis (RO) filter is the heart of the system. It removes impurities and contaminants down to an incredibly small size of 0.0001 microns, leaving only pure water molecules to pass through. The filtered water then passes through a fine GAC filter, providing final polishing before it is delivered to the faucet.

To further enhance the water’s taste and quality, an Alkaline Remineralization filter is included in the system. This filter restores healthy minerals and natural alkaline balance, making the water taste better and more refreshing. The end result is great-tasting bottled-water quality right from your own faucet.

It’s important to note that if the water inlet pressure is below 45 psi, a booster pump is needed to ensure optimal system performance. On the other hand, a pressure regulator is needed if the water pressure is 70 psi or above.

Overall, the iSpring RCC7AK water filtration system is an excellent choice for anyone looking for high-quality drinking water at home. Its comprehensive filtration process ensures that you and your family have access to clean, safe, and refreshing water.

The iSpring RCC7AK reverse osmosis (RO) system is designed to remove a wide range of contaminants from your water supply, including dissolved solids, heavy metals, pesticides, chemicals, and more. The system uses a multi-stage filtration process that includes pre-filters, a reverse osmosis membrane, and a post-filter.

The system is rated to remove up to 99% of dissolved solids and up to 99% of contaminants such as lead, chlorine, arsenic, fluoride, heavy metals, bacteria, viruses, and more. It comes with a high-quality reverse osmosis membrane rated at 0.0001 micron.

The system’s performance can be affected by factors such as water pressure, water temperature, and the quality of the water supply.

The performance will also depend on the usage, the quality of the water supply and the replacement schedule of the filters. Regular maintenance and filter replacement is essential for maintaining the performance of the RCC7AK.

In general, the iSpring RCC7AK is expected to deliver high-quality purified water and has certifications from WQA, NSF/ANSI. These certifications are good indicators that the system meet industry standards for water filtration performance and safety.


The installation of the iSpring RCC7AK reverse osmosis (RO) system is relatively straightforward and can typically be completed in just a few hours. It is recommended to have some basic knowledge of plumbing to ensure the proper installation.

Here are the general steps for installing the iSpring RCC7AK:

  1. Turn off the main water supply to the house.
  2. Locate the nearest cold water supply line under the sink or in the basement or crawlspace. This will typically be a copper or plastic pipe.
  3. Cut the cold water supply line using a pipe cutter or a saw, making sure to leave enough room for the RO system’s water supply adapter to be connected.
  4. Connect the water supply adapter to the cold water supply line, making sure that it is securely tightened.
  5. Connect the RO system’s output tubing to the water supply adapter and then to the cold water supply line.
  6. Connect the drain tubing to the RO system’s drain saddle valve and then to the sink drain.
  7. Turn the main water supply back on and check for any leaks.
  8. Flush the system by running water through it for about 5 minutes to remove any debris or carbon fines.
  9. Install the filters and reverse osmosis membrane according to the manufacturer’s instructions
  10. Once the installation is complete, you should test the water for proper filtration and performance.

It’s important to follow the manufacturer’s instructions and check local plumbing codes when installing a reverse osmosis system to make sure everything is up to the standard. Also, If you’re not familiar with plumbing, it is recommended to seek professional help for installation.


The iSpring RCC7AK reverse osmosis (RO) system requires regular maintenance to ensure proper function and maximum performance. Here are some general maintenance steps to keep your RCC7AK in good working condition:

  1. Change the filters: The pre-filters and post-filter (carbon filter) in the RCC7AK should be replaced every 6-12 months, or more frequently if the water is of poor quality or if you notice a decrease in water flow or a change in the taste of the water.
  2. Check the water storage tank: The water storage tank should be checked for leaks, and if leaks are found, the tank should be replaced.
  3. Clean the faucet: The faucet should be cleaned periodically with a mild detergent to remove any build-up of minerals or debris.
  4. Sanitize the system: the system should be sanitized every six months or when the water flow slows down.
  5. Monitor water waste ratio: Keep an eye on the water waste ratio, if it is too high, it may indicate a clogged membrane or a malfunctioning part of the system.
  6. Storage: If you’re going away for an extended period of time, or if the system will not be in use, it is recommended to drain the storage tank and the lines to prevent bacterial growth.

Regular maintenance of your RCC7AK will help ensure that the system is working at its best and prolong the life of the system. It’s important to follow the manufacturer’s instructions for specific maintenance and replacement schedules for your system.
