The dual stage, flame laminated foam offers two different pore sizes to create more trapping area for even the smallest dust particles and both stages are not glued, but heat sealed, to provide maximum air flow. It is reticulated to increase dirt-stopping surface area and foam strength. The glue seams will withstand harsh solvents and gas; pull as hard as you can, foam will rip before the glued seam. Light color foam easier to spot where the filter oil has covered and where it has not.
