Use this RS PRO sheet filter with your ventilation systems. Its open-cell polyurethane (PUR) foam material captures harmful or unwanted particles while letting air pass through. The material's flexibility and strength ensure high-performance filtration in a range of environments.


You can install this unit on the entrance frame to your ventilation system, so it's easy to remove, wash and reattach if necessary. The porosity rating of 30 PPI (pores per inch) helps boost performance by capturing particles and balancing airflow. You can also use it multiple times, as it's designed to maintain its shape.


The sheet filter's G3 grade means it has high-quality dust-capturing pores. It's commonly used as a pre-filter for catching large particles that can cause damage to ventilation systems.
