Twin Air starts with a Dual-Stage Air Filter and completely submerge it in BIO Liquid Power Filter Oil. After the filter is massaged to ensure all pores are evenly coated with oil, it’s placed in a temperature-controlled room to allow the oil to completely cure. You just open the resealable bag and install.

Twin Air’s fused-dual-layer design combined performance and protection. The fused layers of open-pore foam and fine inner foam trap even the smallest particles. The new, rounder design boosts airflow. So do the minimized seams made possible by a revolutionary micro-gluing process: Shorter seams = more foam = more flow.

• DUAL-LAYER FOAM: made to our specifications, with cells that are evenly sized and distributed
