Pleated Panel Air Filters
The pleats create a large surface area for filtering without reducing airflow. These filters are typically used as replacement filters in HVAC equipment. The cardboard frame is treated to resist humidity, and the galvanized steel grill prevents sagging.
These filters meet UL 900 flame retardance requirements. Actual size is up to 5/8” less than trade size.
