Abstract
A fluid filter media including a first media layer, a second media layer, a filter layer disposed between the first media layer and the second media layer, and a plurality of spaced apart weld points that couple the first media layer, the filter layer, and the second media layer together, where the weld points distort the surface of the first media layer and the second media layer, the fluid filter media is folded back on itself to form a plurality of pleats, and the surface distortions permit fluid flow through the fluid filter media when adjacent surfaces of the fluid filter media touch.
