1 Target substance and size: sulfate ion / 0.4 nanometer. The inspection result (water purifier performance evaluation based on KC mark) of the “Ministry of Environment Notification of Designating Standards, Specifications and Inspection Agencies for Water Purifiers” by Korea Environment Water Works Institute or Korea Conformity Laboratories, a water purifier performance testing agency, in pursuant to Article 43 of Law for the Management of Drinking Water. The performance of the product was evaluated at a pressure of 3.5kgf/cm2 on the product inlet after adding 400mg/L of tap water and sulfate ion to the tank. The removal rate was calculated after sampling and analyzing sulfuric acid ions at the end of extraction (70% based on the acceptable removal rate). As of March 2017, the sulfuric acid ion removal efficiency of the selective purification performance certificate for Coway RO water purifier currently on market in Korea: 93~100%
