The Filter 🙌🏼 Utilising the latest technologies in open-cell foam 3D profiling, the @funnelwebfilterau pyramid profile effectively doubles the filters outside surface area without increasing its overall size. Compared with conventional foam air filters, the Funnelweb has been designed to trap and hold more dust on the outside surface of the filter, maintain optimal airflow by spreading dust build over an increased surface area, and enable longer filter service intervals! 🤑
