Pro-source PRO18182AN Pleated Air Filter 18x18x2 Merv 8

Product Description

The PRO-SOURCE PRO18182AN is a wire-backed pleated air filter rated MERV 8, designed for residential and light commercial HVAC systems. It captures 30 to 35 percent of airborne particles using antimicrobial synthetic filter media backed by a wire support structure that maintains pleat shape under airflow. The beverage board frame holds nominal dimensions of 18 x 18 x 2 inches, with actual dimensions of 17-3/4 x 17-3/4 x 1-3/4 inches. Rated airflow is 844 CFM at a maximum face velocity of 500 feet per minute. HVAC technicians and service professionals install this filter as a standard replacement in forced-air systems.

This filter fits residential and light commercial air handlers, furnaces, and fan coil units requiring an 18 x 18 x 2 inch filter slot. Its MERV 8 rating makes it suitable for general-purpose filtration where moderate particle capture efficiency is required without excessive pressure drop. Initial resistance measures 0.14 inches water gauge at 375 feet per minute and 0.20 inches water gauge at 500 feet per minute, keeping static pressure impact low across a wide range of system operating conditions. The antimicrobial treatment on the media inhibits microbial growth on the filter surface during its service life.

Key Features

• MERV 8 rating with 30 to 35 percent particle capture efficiency per ASHRAE 52.2

• Wire-backed pleat construction maintains media shape at airflows up to 500 FPM
• Beverage board frame with integrated construction for rigid, secure fit
• Low initial resistance: 0.14 in. w.g. at 375 FPM and 0.20 in. w.g. at 500 FPM
• Rated for operating temperatures up to 200 degrees F
• Listed to UL 900 and tested per ASHRAE 52.2

Compatibility

Designed for use with any forced-air HVAC unit requiring an 18 x 18 x 2 inch nominal filter size, including residential furnaces, air handlers, and fan coil units. The manufacturer designates this filter as suitable for any unit accepting this nominal size.

Installation Notes

Installation of replacement air filters should be performed by a qualified HVAC technician or trained service professional. Power down or shut off the air handler or furnace before removing the old filter and inserting the replacement. Verify that the airflow direction arrow on the frame aligns with the direction of air travel toward the blower. Replace the filter at regular intervals based on system runtime and site conditions to maintain rated efficiency and avoid excessive pressure drop.
