Summary of Shanghai CDC Official Test Data and Experimental Results
Our company formally entered the Mainland China market in 2012 and initiated the import permit application for Top Spring products early that year. This application required passing rigorous testing by the "Institute for Environmental Health and Related Product Safety" under the Chinese Center for Disease Control and Prevention (CDC). The stringency of their review standards is considered comparable to the international NSF certification system.
Following a high-standard inspection process, Top Spring successfully passed the comprehensive audit on October 1, 2012, and officially obtained the import license, fully demonstrating the product's exceptional safety and quality.
Notably, in the water environment of Shanghai with a total hardness as high as 243 mg/L, the Top Spring system continued to effectively treat water and met both local and international drinking water sanitary standards, proving its superior purification performance and stable quality.
Within a rated water output of 4.00m³ at a flow rate of 2.00L/min, the filtered water quality fully complies with the "Sanitary Standard for Drinking Water".
Removal rates for oxygen consumption, volatility phenols, chloroform, and carbon tetrachloride are excellent, far exceeding the 80% standard required by hygiene regulations.
