Pleated Media in air filters is a folded synthetic or blended fiber material designed to increase surface area for enhanced particle capture and airflow efficiency. Its structure allows it to trap dust, pollen, mold spores, and other fine contaminants while maintaining low resistance, making it ideal for residential, commercial, and industrial HVAC systems. Compared to flat filters, pleated media offers longer service life, higher MERV ratings, and improved indoor air quality performance.
