A reverse osmosis water filtration system can protect you and your family's health from pollutants in tap water. The RO filtration system can reduce the chemical contaminants that the typical carbon filters cannot effectively eliminate. This under sink water filtration system effectively removes TDS, limescale, up to 99% of over 1,000 contaminants, including lead (removes up to 98%), chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more.
