Water Production

Like other RO- water filters, Water production depends upon the water pressure and the water temperature.

iSpring RCC7 is rated for producing 75 Gallons of purified water. It can produce less or more than 75 gallons of water but it does not happen all the time.

To produce this rated amount of water, your water pressure should be ideally equal to or more than 45 psi. Almost every household has water pressure between 45 to 55 psi, but it is recommended to cross-check the water pressure.


All the RO water filter systems, Wastes the water before it actually produces a gallon of purified water. And the water waste ratio determines the Efficiency of the RO-system. A lesser water waste ratio indicates higher efficiency.

The Residential reverse osmosis system with the water waste below or equal to 3-4 Gallon is considered as an efficient system.

iSpring RCC7 wastes 3 gallons of water before producing a single gallon of purified water. This water waste ratio is acceptable, as it is below 3 gallons.

Water waste can increase your cost of ownership. Because more water waste means more water consumption. Its water waste is better than most of the systems available in the market. But still, you can reduce this amount of water waste to 1 gallon by using the permeate pump.

Permeate pump is capable of increasing the efficiency of up to 80% and also the productivity by up to 50%.

Filtration process

iSpring RCC7 uses the 5-stages for the filtration of water. This undersink reverse osmosis system has the capability of removing 98% of contaminants from your feed water. It can remove more than 1000 type of contaminants from your water.

Every filter in the filtration process is charged with the responsibility of removing contaminants. Before the water reaches your faucet its filtration process makes the feed water completely pure, contaminants free, cleaner, and healthier to drink.

Let’s have a look:

How does its Filtration system work?

The filtration process is identical to all the 5-stage reverse osmosis systems.

The water first goes through the Pre-filters. The First 3 stage filters are known as pre-filters.

1st Stage: Responsible for removing Sediments, dust, and the rust from water

2nd Stage: It is GAC filters that remove the taste, odor, and chlorine.

3rd Stage: Ensures that water is completely pure from odors and chlorine and other particles. It removes all the possible particles that previous stage filters may leave in the water. It helps the RO-Membrane (4th stage) to perform its operation efficiently.

After Pre-filters, water is treated By RO-Membrane

4th stage: At this stage water passes through the RO-Membrane. The RO-Membrane is capable of removing contaminants down to 0.001 microns. It rejects the sodium, arsenic, calcium, potassium, and many other larger contaminants from the water.

Now the Post-filters come into an action

5th stage: It is the carbon filter. It ensures that the fresh-tasting water reaches your faucet. It removes the odor and unwanted tastes from the storage tank.

Filter replacement

The duration of filter replacement has a direct impact on your cost of operation. The initial cost must be the concern but maintenance cost should be a foremost concern before purchasing a Reverse osmosis filtration system.

The quality of filters is enough good that you don’t need to change the filters too frequently.

Although, it is recommended to change the filters after 6-12 months and RO-Membrane has to be changed after every 2 years.

But keep in mind, more contaminated water can reduce the lifespan of the filter of any Reverse osmosis system.

Thanks to transparent housing, it helps you to identify the time when filters need to be replaced. The filter replacement process is straight-forward but demands a little bit more effort than modular design.
