This whole house sediment filter is designed to improve your tap water by reducing the sediment and turbidity in the water through its 5 microns filtration. It also uses the mechanical method in order to trap other suspend solids found in the water such as sand, oil, and plankton. This sediment filter is perfect to use in household with sizes of up to 4 people. The filters should be replaced every 6 months or when a noticeable pressure drop occurs.
