Purolator™ 5042193776 20x25x1 in Disposable Synthetic Panel Furnace Air Filter

The P312 disposable synthetic panel filters are ideally suited for residential, commercial, or light industrial use. Polyester media was developed for situations where synthetic media products are required.
The Purolator P312 frame is produced using post-consumer recycled materials. The unique Monobond pinch frame concept involves a one-piece frame sealed to the media under heat and pressure. This construction feature produces a continuous bond of media to board around the periphery of the frame, eliminating weak corners and air bypass. The use of a high tensile strength binder increases the integrity of the seal, allowing the filter to withstand varying temperatures and humidity levels.
The synthetic media used in a P312 consists of polyester fibers bonded together in an interlocking pattern of tiny lint and dust traps. This configuration maximizes dust loading while minimizing resistance to airflow and surface loading.
P312 filters perform best in conditions where large quantities of lint and dust are present. The rugged construction makes these filters industry leaders in the high-velocity system, prefilter market.
