This is a 2-pack of these replacement filters.
With two layers of progressively finer mesh synthetic media between 100% polyurethane top and base, this high flow, "oil-free" conical performance filter provides maximum convenience and easy maintenance with excellent airflow. Washable and reusable for multiple cleanings, the tall open evenly spaced pleats provide excellent dust holding capacity for a longer service cycle between cleanings. Pliable polyurethane flange with integrated bumps insures tight, no leak seal over the life of the filter.
