The Pitco PTPP10613 Fryer Filter Envelopes provide dependable filtration for high-volume commercial kitchens. These filter envelopes measure 18-1/2" x 20-1/2" and are engineered to capture food particles, carbon buildup, and sediment during the oil filtration process. They work by allowing hot oil to pass through the filter material while trapping contaminants that can affect oil quality and cooking performance. By helping maintain cleaner oil, the envelopes support more consistent frying results, reduce flavor transfer between batches, and contribute to longer oil life. Packaged in a convenient 100-pack, they offer a practical solution for maintaining efficient day-to-day fryer maintenance and operation.
