NSF-certified RO systems are designed to reduce or eliminate contaminants, such as lead, arsenic, and other impurities, from your drinking water. The cost of an NSF-certified RO system can vary depending on the features and type of filtration the system offers.
  • Filtration Process: A Reverse Osmosis (RO) Drinking Water System is a water purification system that uses several stages of filtration to eliminate contaminants from your drinking water. It begins with a sediment filter that removes large particles such as sand and silt, followed by a carbon filter which absorbs impurities such as chlorine. Next, the water passes through the RO membrane, where the contaminants are removed down to molecules. The last stage is a post-filter which ensures that any remaining particles are eliminated from your water.
  • Size: RO drinking water systems come in various sizes to accommodate different household needs. Prices can start around $200 for a smaller system, but larger systems may cost between $400 and $600.
