Filtration Process

Now we will explain all the filtration stages that work together to bring you pure water for drinking purposes. The water that you get from RCC7 is so pure that you can even use it to make infant formula without any worries. Once you start consuming water from RCC7, you will notice a definite improvement in your family’s health.

The 5 stages used in the filtration process are explained below along with the filters used in the respective stage

Stage 1 – Sediment Filtration Stage

The first stage filters out all the sediments in your water. It can capture sediment down to 5 microns. At this stage, the filter catches rust, sand, dirt, silt, and other such particles. This process ensures that you do not get any harmful sediment in your water, and it also ensures a long life of the next filters.

iSpring FP15X2 5 micron

Filter Used: The first stage uses a PP sediment filter. It has a lifetime of 6-12 months. Depending upon the quality of water you are getting at your home; this filter can last more than 12 months if the water quality is better. However, you must not use this filter for more than 12 months as a clogged filter can decrease the filtration quality or affect the working of the next 4 filters.

Stage 2 – Granular Activated Carbon Filtration Stage

When the water reaches the second stage, chemicals like chlorine, chloramines, bacteria, viruses, and other harmful contaminants are removed from the water source. The filtration rating for this stage is 5 microns.

Filter Used: The filter used in this stage is made from coconut shell carbon. It is a high-quality, durable material that enhances the efficiency and life of the filter. It has a lifespan of 12 months.

Stage 3 – Carbon Block Filtration Stage

The next stage is the carbon block filtration stage. It is placed to ensure a step further for your water filtration. At this stage, volatile organic compounds, industrial solvents, insecticides, herbicides, pesticides, pharmaceuticals, cloudiness in the water, and odors are removed.

Filter Used: The filter used is the carbon block filter on the third stage. It is a bonded PAC media with polyolefin pre-filter and polyethylene netting for extended life. It is one of the most versatile filters as it can be used in various models from iSpring. It also has a lifespan of 1-year.

Stage 4 – Reverse Osmosis Stage

The fourth stage is the reverse osmosis stage. It is the heart of the system as the membrane ensures that nothing other than water passes from this membrane. It will filter out heavy metals, any residual chlorine, and other harmful contaminants from your water. It has a filtration capacity of 0.0001 microns. It is so small that only water molecules can pass through the system.

Filter Used: The filter used in the 4th stage is a reverse osmosis membrane. iSpring has made the membrane dry to make its storage easy, and you don’t have to wash a dry membrane before usage. The membrane has been independently tested by third-party to meet all the NSF/ANSI standards. The membrane can last for 2-3 years. The quality of your water greatly impacts the lifespan of the membrane.

Stage 5 – Post-Carbon Stage

The fifth and final stage is the post-carbon stage. Although the 4th stage ensures that there is nothing harmful left in your water, it is placed to ensure total removal of chlorine. At this stage, your water is also polished to give you odorless drinking water.

Filter Used: The post carbon filter is made with high-quality laboratory tested carbon to give you the best results. It has a lifespan of 12 months.

Filter Replacement: The next thought that comes in mind is the ease of replacing the filters. You have to remove the housings, with the help of a plastic spanner (included), remove the filter, insert the new one, tight it up and then place the housing back. It may take some time, but it is not a difficult thing to do.

Installation

The system has been designed to facilitate a self-installation. The user manual is detailed and guides you step by step for installation. All the equipment needed to install the system comes in the box.

Drilling a hole for the faucet can be a bit problematic for you, but it can be managed with a standard drill and set of tools. There is no clause of warranty violation in case of self-installation. For a leak-proof installation, insert the pipes ½ inches in the system.

Technical Details

You get 4-colored tubing (1/4 inch OD), spare fittings, and O-rings along with feed water adapters, drain saddle and water detector. The optimum water pressure for this unit is 40-80 PSI; above 80 PSI, a pressure regulator should be installed.

Cost Analysis

Quality water systems like iSpring RCC7 last more than a decade. It is imperative to know what you will be paying in the long run. Once you have made the purchase, you will notice that your water filtration cost will significantly go down. With RCC7, your monthly cost will be around $18-20 on an annual basis.

Compared to bottle watered, over the top filtration dispenser, it is very negligible, and you will not only be getting purified water, but you will also be saving some handsome amount of money as well.

Warranty
