Pro-source PRO10393 Pleated Air Filter Merv 8 12x24x4

Product Description

The PRO-SOURCE PRO10393 is a wire-backed pleated air filter rated MERV 8 with 35% particle capture efficiency, designed for use in residential and commercial HVAC air handling units and furnaces. Built with a synthetic pleated media and a paperboard frame, it delivers reliable filtration at a maximum face velocity of 500 feet per minute (FPM) and an airflow capacity of 1,000 CFM. The wire backing supports the media under airflow load, maintaining pleat geometry throughout the service cycle. Nominal dimensions are 12 x 24 x 4 inches, with actual dimensions of 11-3/8 x 23-3/8 x 3-3/4 inches. Installation requires no tools beyond a screwdriver for access panel removal.

This filter is suited for standard residential furnace and air handler applications as well as light commercial systems where MERV 8 filtration is specified. It captures common airborne particles including dust, pollen, mold spores, and lint. At an initial resistance of 0.14 inches water gauge at 500 FPM and a final resistance of 1.0 inch water gauge, it fits within the static pressure tolerances of most residential and small commercial blower systems. The 4-inch depth supports extended service intervals compared to 1-inch and 2-inch alternatives, making it a practical choice for high-run-time systems.

Key Features

• MERV 8 rated with 35% particle capture efficiency per ASHRAE 52.2-2012
• Wire-backed pleated synthetic media maintains pleat shape under airflow
• Paperboard frame for standard filter track compatibility
• Maximum airflow of 1,000 CFM at up to 500 FPM face velocity
• Rated for continuous use up to 200 degrees F
• UL 900 listed for fire safety compliance

Compatibility

Designed for use with any HVAC unit accepting a nominal 12 x 24 x 4 inch filter. Verify actual filter opening dimensions against the actual size of 11-3/8 x 23-3/8 x 3-3/4 inches before installation.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel. Shut down the air handler or furnace at the disconnect before replacing the filter. Confirm airflow direction arrow on the filter frame aligns with system airflow toward the blower. Filters meeting ASHRAE 52.2 and UL 900 standards are commonly required by commercial building codes and HVAC system specifications.
