With an ideal balance of dirt-trapping efficiency and dirt-holding capacity, every FRAM oil filter uses a special blend of fibers and resin providing a proprietary filter media that delivers excellent engine protection.
Features
- The most commonly used filter media is cellulose, which is a natural material that presents a random and irregular field of fibers to the oil. By itself, it can only deliver about 80% dirt-trapping efficiency.
- By adding microscopic synthetic fibers, small windows are created that trap the smaller dirt particles without affecting the flow of oil. Blending synthetic fibers with cellulose increases a filter’s dirt-trapping efficiency and its dirt-holding capacity for higher levels of engine protection and longer filter life.
