Many pollutants, such as silt, chlorine, bacteria, viruses, heavy metals including lead and mercury, pesticides, and volatile organic compounds (VOCs), can be successfully eliminated from water by installing a whole-house filtration system. To handle a variety of contaminants, these systems frequently use several filtration stages, including UV sterilization, activated carbon filters, and sediment filters. You may have safer, cleaner water throughout your house by installing a whole-house water filtration system, which also improves the flavor, odor, and general quality of the water.
