Purolator P312
P312 Poly Filters are Ideally suited for residential, commercial, or light industrial use, the polyester media was developed for situations where synthetic media products are required.


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.


  • The P312 frame is produced using post-consumer 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.
  • Improved aerodynamics reduce restriction to air flow
  • Safe, easy, fast installation
  • Larger effective filtering surface area. This configuration maximizes dust loading while minimizing resistance to air flow and surface loading.
