Mini Pleat HVAC Filter

Mini-pleat filters are designed with more filter media per area than a standard panel filter. These mini-pleat air filters are specifically designed to provide high levels of air filtration efficiency to remove pollen’s, molds, dust and other airborne irritants. Available in a variety of sizes to accommodate any air intake system, these filters provide improved airflow and need to be replaced less frequently.

ISC’s mini-pleat technology delivers high performance in a small package. Requiring only a fraction of the space required by other rigid filters, these panels make the most of their surface area. These HVAC Filters combine excellent filtration performance with low airflow resistance and long filter life.

These filters combine state-of-the-art mini-pleat construction techniques with superior reliability to offer maximum value for commercial and industrial applications. Additionally, these filters offer unique advantages over the traditional rigid box filter including lower freight costs, reduced storage area requirements and less impact on landfills.
