Pleated air filters capture airborne contaminants more effectively than non-pleated air filters because the pleated filter media provides more surface area for trapping contaminants than non-pleated media. These filters are commonly installed in HVAC systems in food and beverage, healthcare, hospitality, education, and industrial facilities to remove contaminants from the air stream and improve the quality of the air.

High-Efficiency Extended Surface Filters for High-Temperature Applications
Multi-Pleat HT filters are designed for ovens and air filtration systems with continuous operational temperatures up to 500°F (260°C). This product is widely used in applications such as paint spray booths, baking systems, drying ovens, and in any system where elevated operating temperatures require a more specialized type of air filtration.
The Multi-Pleat HT is constructed with a medium efficiency extended surface media element secured in a 24 gauge aluminized steel enclosure frame to resist flaking. The MERV 8 media element is composed of specifically formulated, extended surface glass microfiber, designed to provide superior performance without degradation in high-temperature systems. The media element is bonded to the entire interior surface of the frame to eliminate air bypass, and the radial design of each pleat ensures total media utilization. The media element is supported downstream by a high temperature expanded metal grid.
