New Design is backfire Resistant and helps prevent messy and dangerous fuel backfires
Fused-dual-layer design for a combined increase in performance and protection
Revolutionary micro-gluing process minimizes seams for added protection
Washable and reusable up to 50 times without replacement
New Round design boosts air flow
Twin Air’s breakthrough, fused-3-layer design (now widely copied) for 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.
