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.

Quick-Disconnect Reusable Metal Panel Filters
Magnetic strips on the back of the frame make these filters easy to install and remove. Because you don’t need to disassemble equipment to remove them, they are often used as prefilters on steel air intake louvers, metal cabinets, and metal grid systems. These filters can be washed and reused. They are made of polypropylene, so an electrostatic charge attracts dust and particles to them.

Prefilter Air Filter Pads
These pads are an economical choice for protecting more expensive filters that catch finer particles. Cut to the size you need; frames are sold separately.
Pads meet UL standards for flame retardance.
Synthetic fiber pads have a heavy dust-holding capacity and withstand poor weather conditions such as rain, snow, and wind. Often used in upstream HVAC applications, they’re durable and can catch dirt, dust, hair, and other large particles. The material of these pads is also known as hog hair.
