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.
