20" x 20" x 1" Disposable Synthetic Warm Air Panel Filter, Merv 4

Details

The P312 disposable synthetic panel filters are ideally suited for residential, commercial, or light industrial use. The polyester media was developed for situations where synthetic media products are required. 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 air flow and surface loading.
