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.
