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 is made of food-grade high capacity material that 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 under the highest standards in the industry 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.
The RO membrane removes not only harmful pollutants but also most healthy 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 Remineralization filter, iSpring alkaline filter (FA15) restores healthy minerals and produces a balanced alkalinity, giving the water a better taste. It uses all 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.
The Sediment Filter works as the first barrier in the Reverse Osmosis System, removing solid particles like silt, rust and dirt from the water and reducing a significant percentage of contaminants in the water. It prevents the other filters from getting clogged with fine particles and reduces the risk of damages to the other components.
iSpring’s first stage Sediment Filter (FP15) features a 5 micron size, perfect for capturing most of the fine sediments in the municipal water and preventing issues from clogs and pressure loss with filters that have smaller micron sizes.
