Its 20% to 30% filter efficiency at capturing particles between 3.0 and 10.0 microns ensures improved air quality without restricting airflow, contributing to efficient system performance and energy savings.

This spun glass media filter is non-electrostatic, pleat-free, and does not include metal mesh support, allowing for smooth airflow and easy cutting without fraying. It is not designed to capture bacteria or viruses, but its dust- and lint-trapping capabilities make it an excellent first-line defense in multi-stage filtration systems.
