Description
1. Product Overview
Pre-filter foam pads are high-performance open-cell polyurethane foam filtration media designed to capture coarse dust, fibers, lint, and airborne contaminants before they reach primary and secondary HVAC filtration systems. Widely used in commercial, industrial, and OEM air handling applications, these foam pads help extend the service life of downstream filters while improving airflow efficiency and reducing maintenance costs. Their washable, reusable construction provides an economical and sustainable filtration solution for continuous operation. As industries prioritize energy efficiency and equipment protection, pre-filter foam pads have become an essential component in modern HVAC systems.
