Abstract
A filtration device to filter cooking oil is provided having an upper layer comprised of a filter paper and a lower layer comprised of a filter pad. The filter paper of the upper layer includes pleats defining a plurality of food particle receiving channels over a substantial portion of a central area of the filter paper. The filter pad is stitched to a peripheral portion of the filter paper to form a multi-layered filtration device having a central pleated region in which the upper and the lower layers are unbonded to each other. The central pleated region is configured to accumulate food particles above a threshold size as the filter paper and filter pad cooperatively filter cooking oil during a filtration operation. Methods of making and using filtration devices are also provided.
