In this comprehensive iSpring RCC7AK Reverse Osmosis review we will analyze the filtration capabilities, the system design features, its performance, its capacity, the installation & maintenance process, discuss customer reviews, and potential alternatives for this Reverse Osmosis system.

Let’s get started!

iSpring RCC7AK Reverse Osmosis System Overview

The iSpring RCC7AK Reverse Osmosis is a point-of-use (POU) system that reduces up to 99% of TDS (total dissolved solids) from the water. This RO system includes a storage tank and it is installed under the sink to give you clean water to drink and cook in your kitchen faucet.

This system filtration process consists of 6 stages which mean that it can remove a great range of harmful contaminants from the water, as each filtration stage targets different contaminants. 

The last stage includes an alkaline filter to add back healthy minerals that were lost in previous stages, like calcium and magnesium to the water, which balances the water pH and improves its taste.

The iSpring RCC7AK includes quick-connection color-coded tubes, that together with physical and online instructions make the installation process easier.

iSpring RCC7AK Reverse Osmosis Filtration Capabilities

The iSpring RCC7AK Reverse Osmosis system is a powerful filtration system that can remove 99% of contaminants from the water, which represents more than 1.000 contaminants, such as sediments, rust, chlorine, fluoride, sodium, bad taste & odors, chemicals, lead, arsenic, asbestos, as much more.

This effective filtration is achieved by combining 6-stages of filtration that includes the following steps:

  • Stage #1: Consists of a PP Sediment filter, that removes sediments, dust, sand, dirt, rust, and other larger particles
  • Stage #2: Consists of a Granular Activated Carbon, that removes chlorine, cloudiness, bad taste & odors
  • Stage #3: Consists of a Carbon Block, that removes chloramine, VOCs, harmful contaminants, etc.
  • Stage #4: Consists of a Reverse Osmosis Membrane with 0.0001 microns, which removes a huge amount of contaminants
  • Stage #5: Consists of a Post Carbon, that improves water taste by removing any potential bad taste & odors from the storage tank
  • Stage #6: Consists of an Alkaline Filter, that increases water alkalinity adding back beneficial minerals

The RO membrane is really effective at removing contaminants, but it also removes some beneficial minerals from the water, decreasing its pH. The iSpring RCC7AK Reverse Osmosis includes an alkaline filter on the last filtration stage to restore healthy minerals in the water, balancing its alkalinity and improving its taste.

The iSpring RCC7AK Reverse Osmosis system has the NSF 58 certification, which ensures the system was independently tested and certified for TDS reduction, and that it can effectively reduce TDS in water and remove most contaminants.

iSpring RCC7AK Reverse Osmosis Design Features

The iSpring RCC7AK Reverse Osmosis system includes helpful design features in it that make a very complete RO system.

This system includes a pressurized storage tank with a capacity to store 3.2 gallons of filtered water, so you will have a good amount of clean water available to consume. It also automatically refills when the water is consumed, so you won’t have to wait much time to have water available.

It also includes a transparent housing for its first filter, which lets you check when the sediment filter is full of contaminants and needs to be replaced. 

The iSpring RCC7AK Reverse Osmosis comes with a lead-free designer faucet, that is resistant to spots and easy to connect to simplify the installation process.

This RO system includes a leak detection system that shuts off the system if detects excess water, protecting your home and appliances.

The iSpring RCC7AK Reverse Osmosis includes leak-free fittings and a 4-color tube set to make the installation process easier and prevent the system from leaking.

iSpring RCC7AK Reverse Osmosis Performance

The iSpring RCC7AK Reverse Osmosis system has an efficiency, or waste water ratio, of 1:3, meaning that it created 3 gallons of waste water for each gallon of clean water.

Typically RO systems generate 3 to 4 gallons of waste water per gallon of filtered water, so this system is not worse than the average. That being said, there are systems that are much more efficient and will only produce one or even fewer gallons of waste water.

If avoiding wasting water is important for you, you can always reuse the waste water for other activities that nor drinking or cooking, like watering your plants or washing your car.

iSpring RCC7AK Reverse Osmosis Capacity

One important factor to consider when choosing a Reverse Osmosis system is the capacity, which means how many gallons of water can the system filter in a day, measured in gallons per day (GPD).

If your family needs more water than the system capacity, it won’t be a good fit for you because you won’t have enough clean water available.

The iSpring RCC7AK Reverse Osmosis system can filter up to 75 gallons of water in a day (GPD), which is average with some of the best RO systems.

This system includes a RO storage tank with the capacity to store 3.2 gallons of filtered water, so you will always have around 3 gallons of filtered water ready to use. The system automatically refills the tank when the water is used, so you don’t have to wait much time to have more clean water available.

75 gallons of water per day is more than enough for most families, so this system capacity should not be a problem for you. Anyway, you can always estimate how much clean water your family will need using our water usage calculator.

iSpring RCC7AK Reverse Osmosis Installation & Maintenance

The iSpring RCC7AK RO system installation should be easier than the typical installation of an RO system because this product includes all the required components and comes with leak-free fittings, a 4-color tube set, and easy to follow instructions and videos to make the installation process as smooth as possible.

Many customers mentioned that the installation process was simple and straightforward, and they were able to complete it in a couple of hours or less. If you like DIY activities, this should not be a problem for you.

iSpring also offers lifetime technical support which is handy not only during the installation process but also in the future if you have any questions or need help with the system maintenance.

Just make sure that at the start of the process you select the right place under the sink to place not only the RO system but also the storage tank. And leave some room for you to be able to replace the filters in the future.

To change the filters you will need to use the wrench that comes with the system to loosen the filter housing. Then remove the housing, replace the old filter with the new one, and screw the housing again. This activity should not take you more than 5 minutes to complete.
