The pleated panel filter is produced with 100% polyester fibers, engineered by whalesens for HVAC systems.

Featuring high dust-holding capacity and low air pressure drop, this pleated filter has more surface areas for trapping airborne contaminants than other types of filters. They are commonly installed in HVAC systems as prefilters or secondary filters in hospitality, education, food, industrial or commercial facilities with medium filter efficiency. They can also be used at the inlet or return air vent of HVAC for cleanrooms.

These filters withstand temperatures up to 80°C and are highly waterproof. With metal frames, they are easy to change or dispose of.
