Their bonded media contains more fibers per unit area offering far greater volume dirt holding capacity than other filtration fabrics. Due to uniformly placed weld spots, their advanced bonded fabric is strong and robust, and returns to a high state of original performance after cleaning, meaning greater usability, longer cleaning cycles, and less service time. Advanced Filtration Fabric - 4oz media with the highest fiber count, holds more dirt. Longer Service Life - Clean less frequently and lasts longer.
