Since our founding in 1973 we have continuously developed breakthrough innovations in the manufacturing of Activated Carbon, Melt Blown, Non-Woven and Paper filter media. We have been able to leverage our innovative technology into a company and build a manufacturing arm around it where we maintain direct control over all aspects of the manufacturing process and the application of our innovative proprietary technologies. This vertical integration has allowed us to create a company where we are now able to deliver superior quality products in terms of efficiency without sacrificing capacity and providing the most competitive pricing that is available. 1973 – Founded as Jeonil Engineering Co. 1979 – Rebranded as Jeonil Filter Paper Co. 1988 – Research Development of proprietary Paper Filtration Technology 1995 – Manufacturing plant relocated to a high capacity industrial complex 1999 – Established a Japanese sales distribution center in Tokyo 2000 – Research Development of Meltblown Synthetic Filtration Media Technology 2000 – Rebranded as Clean Science, Ltd 2000 – QS9000 Certified 2000 – Listed on the KOSDAQ Stock Exchange as a publicly traded company 2001 – Production scale deployment of proprietary Melt Blowing Technologies 2005 – Nationally recognized by S Korean Dept of Commerce for Excellence in Exporting 2006 – ISO-TS 16949 Certified 2006 – Antimicrobial Production Trade Association Certified for Filter Media 2006 – Development deployment of proprietary Layered Paper Filter Technologies 2007 – Development deployment of proprietary Activated Carbon Filter Technologies 2007 – Established a finished goods filter manufacturing plant 2008 – Established a Chinese sales distribution center in Shanghai 2009 – Development deployment of a finished goods manufacturing plant 2009 – Established a N.
