Shibao Air Filter Industry Limited has been a professional manufacturer of air filters and related products for biological and industrial clean rooms for more than twenty years. We pioneered middle and high efficiency filter modules of exclusive and conventional style. Since then, Shibao has become the leader in the field and gained more R&D and manufacture experience than any others in the market. To meet the ever changing environment of the international economy, we started Company Structure Up-Grade Program in 1994. We purchased new production equipment from Japan and the US to begin the production of Minipleat Type Ultra High Efficiency Air Filters (Minipleat Type HEPA & ULPA Air Filter Modules). This makes Shibao the major supplier for high-tech electronics manufacturers. In 1997, Shibao received ISO certificates as another proof to show our further determination to be the leader in both quality and technology in the international market.
