iSpring F5-75 75GPD Water Filter Replacement Set Under sink Replacement Filter 5 -Pack

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. Furthermore, the iSpring 2Nd stage granular activated carbon (GAC) filter (FG15) includes special carbon media that can efficiently prevent bacteria colony growth in your RO systems in order to prolong the lifespan of the reverse osmosis membrane. Activated carbon filters can trap and absorb organic chemicals and chlorine from the water effectively with its ability of mechanical filtration and physical adsorption. It can efficiently remove odors and improve the water taste. 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.
