Reverse Osmosis, when combined with sediment and catalytic carbon filtration, is one of the most all-around effective ways of removing water contaminants. It can eliminate up to 99% of chlorine, chloramines, chemicals, pharmaceuticals, nitrates, sulfates, fluoride, arsenic, lead, asbestos, metals, microplastics, and 1000s of other additional contaminants, when installed and used as directed. When a UV Sterilizer is added, the system will also sterilize bacteria, viruses, and other microorganisms. It is advisable to invest in a reverse osmosis system with activated catalytic carbon to get pure drinking water at home.
