Reverse Osmosis Membrane - 4th Stage

The reverse osmosis membrane is a thin film composite membrane that can remove up to 99% of over 1, 000 contaminants in the water, including lead (removes up to 98% of lead), chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more.

Tested by independent third-party to meet NSF/ANSI standards, iSpring Reverse Osmosis Membrane provides high packing density to remove contaminants. With the 0.0001 micron size, it only allows water molecules to squeeze through and virtually nothing else.

As the heart of a Reverse Osmosis System, each iSpring Reverse Osmosis membrane has been inspected and has passed the quality check before it’s shipped to each customer. It is recommended that you replace the reverse osmosis membrane every two to three years.

6th Stage Alkaline Filter

The RO membrane removes not only harmful pollutants but also most minerals. As a result, a standard 5 stage RO system produces slightly acidic water with a pH of 7.0 or less.

As the 6th stage Alkaline filter, iSpring alkaline filter (FA15) restores minerals and produces pH8-9 alkalinity ro water. It uses natural mineral stones as the filtration media and never sacrifices quality for quantity.

It can last up to 6-12 months depending on your source water and usage.

Sediment Filter

Activated Carbon filters can trap and absorb harmful chemicals and chlorine from the water with its ability of mechanical filtration and physical adsorption. It can remove odors and bad taste.

iSpring 5th Stage Post Carbon filter (FT15) works as the final stage in the RO system to capture any particles that may have accumulated inside the tank before pure water is delivered to the faucet. It can last up to 12 months depending on your source water and usage.

Granular Activated Carbon Filter

Activated Carbon filters can trap and absorb harmful chemicals and chlorine from the water with its ability of mechanical filtration and physical adsorption. It can remove odors and bad taste.

Furthermore, the iSpring 2nd stage Granular Activated Carbon (GAC) filter (FG15) includes carbon media to prolong the lifespan of the reverse osmosis membrane.

Carbon Block Filter

Post Carbon Filter

Activated Carbon filters can trap and absorb harmful chemicals and chlorine from the water with its ability of mechanical filtration and physical adsorption. It can remove odors and bad taste.

iSpring 5th Stage Post Carbon filter (FT15) works as the final stage in the RO system to capture any particles that may have accumulated inside the tank before pure water is delivered to the faucet. It can last up to 12 months depending on your source water and usage.
