This air filter for Hus450 chainsaws features a grid-reinforced nylon frame that resists vibration and breakage during heavy logging work. The layered internal filter paper has uniform pores to block wood chips, sand, dirt and fine dust, preventing cylinder scratches and abrasion caused by inhaled particles. Partition design ensures even air intake to avoid power loss and excessive fuel consumption from blocked airflow. Fully matched with original shape and clips for tool-free installation. The reusable paper filter can be cleaned regularly. It delivers stable filtration for long-term outdoor logging and prolongs engine service life.
