Purolator P312 Furnace Air Filter 18x20x1 (12 Air Filters) Review
Product Overview
The Purolator furnace air filter are industrial strength disposal air filters bonded together in an interlocking pattern of tiny lint and dust traps and is ideally suited for residential, commercial or light industrial gas furnace filter, air Conditioner filter and air handling filters. This configuration maximizes dust loading for improved aerodynamics and does not reduce restriction to air flow. The P312 air filter performs best in conditions where large quantities of lint and dust are present and can be used as a pre air filter. The polyester media was developed for situations where synthetic media products are required and the unique frame is sealed to the media under heat and pressure. This construction method produces a continuous bond 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 Purolator P312 whole house air filter is environmentally friendly, produced using post-consumer materials. Installation is safe, fast and easy. The Purolator P 312 is classified Class 2 by Underwriters Laboratories, Inc
