Pro-source PRO10874 Pleated Air Filter 20x24x1 Merv 9

Product Description

The PRO-SOURCE PRO10874 is a MERV 9 pleated air filter designed for residential and light commercial HVAC air handler and furnace applications. Built with a polyester media and a wire ring-panel frame, it provides reliable mechanical filtration of airborne particulates including dust, pollen, and mold spores. The filter measures 20 x 24 x 1 inches nominal and supports an airflow capacity of 1,667 CFM, making it suitable for standard forced-air systems. Initial resistance starts at 0.07 inches water gauge at 74 FPM, rising to 0.35 inches water gauge at 369 FPM. Maximum rated airflow is 500 FPM, and maximum operating temperature is 120 degrees F. The UL 900 listing confirms it meets standard safety requirements for air filter materials.

This filter installs in any forced-air heating or cooling unit that accepts a 20 x 24 x 1 inch nominal filter slot. Typical applications include residential gas furnaces, split-system air handlers, and packaged HVAC units. MERV 9 performance captures finer particulates than standard fiberglass filters, making it a common choice for households with moderate air quality requirements or light commercial spaces where improved filtration is needed without significantly restricting airflow.

Key Features

• MERV 9 polyester pleated media captures airborne dust, pollen, and mold spores effectively
• Wire ring-panel frame provides structural support without collapsing under normal system static pressure
• 1,667 CFM airflow rating supports standard residential and light commercial air handler applications
• Initial resistance of 0.07 inches water gauge at 74 FPM minimizes system strain at low airspeed
• UL 900 listed filter material meets recognized flammability safety standards
• Maximum operating temperature of 120 degrees F compatible with typical HVAC discharge air conditions

Compatibility

Designed as a direct-fit replacement for any HVAC unit requiring a 20 x 24 x 1 inch nominal pleated air filter slot. No specific system family or model number compatibility is stated by the manufacturer for this part.

Installation Notes

A licensed HVAC technician or qualified service professional should shut off power to the air handler or furnace at the disconnect or breaker before servicing the filter. Verify that the filter slot dimensions match the nominal size before installation. Install the filter with the airflow arrow on the frame pointing toward the blower. Dispose of the used filter per local waste guidelines and check filter condition at regular service intervals per the equipment manufacturer recommendation.
