This RS PRO black sheet filter is designed for use with ventilation systems. It's made from open-cell polyurethane (PUR) foam that captures harmful or unwanted particles while letting air pass through. The material's flexibility and strength help it provide high-performance filtration in a variety of environments.
The sheet filter secures onto a frame at the entrance to your ventilation system so it's simple to remove, wash and reapply as needed. The filter itself is strong enough to retain its shape and quality through multiple uses and it has a porosity rating of 45 PPI (pores per inch), letting it balance airflow and particle capture for effective performance.
The G3 grade means the sheet filter has high-grade pores that capture dust at a consistent rate. As a pre-filter, this grade is an essential first step in high-quality air filtration as it deals with the larger particles that typically damage a ventilation system.
