This whole house filter has 5 microns filtration which eliminates sediments in the water that are smaller than the human eye can see. It uses activated carbon to also improve the chlorine level and turbidity of the water. It is suitable for households with up to 4 people. The filters should be replaced after using it for 3-6 months or when a noticeable pressure drop occurs.
