Performance is Enhanced by a Skin Backing on the Air Leaving Side of the Media

Improved Aerodynamics Reduce Restriction to Air Flow

Safe, Easy, Fast Installation

Larger Effective Filtering Surface Area

Wide Selection of Standard Size

Made in USA

Frame  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

Media  The synthetic media used in a P312 consists if 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

P312 filters perform best in conditions where large quantities of lint and dust are present

The rugged construction makes them industry leaders in the high velocity system, prefilter market

Improved aerodynamics reduce restriction to air flow

Safe, easy, fast installation

Larger effective filtering surface area

Frame  Purolator F312 frames are 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 polyethylene binder increases the integrity of the seal, allowing the filter to withstand varying temperatures and humidity levels

Media  Purolator F312 filters are manufactured with superior grade fiberglass media to guarantee full depth loading and high dust holding capacity

A computer-controlled manufacturing process assures a uniform gradient density pattern in the media

To enhance filtration capability and prevent migration of finer particles, the filter media has a skin backing and is evenly coated with a gelled adhesive

Purolator's F312 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

CREATE A HEALTHIER HOME by preventing airborne allergens from circulating through the air in your home by trapping common airborne allergens as they pass through the MERV 13 filter including dust, pollen, mold spores, bacteria, pet dander and dust mites

BETTER PERFORMANCE thanks to the patented Aprilaire Self-Seal Technology which minimizes the amount of air bypassing the filter

EASY AS 1-2-3 TO INSTALL in the unique Aprilaire Interlock Rail System. Unpack. Slide in. Close the door. Done
