Pro-source PRO10469 Pleated Air Filter Merv 10 20x20x4

Product Description

The PRO-SOURCE PRO10469 is a wire-backed pleated air filter rated MERV 10 with 55% particle capture efficiency. It measures 20 x 20 x 4 inches nominal (19.5 x 19.5 x 3.75 inches actual) and is built with a synthetic filter media bonded to a wire backing for pleat support. The paperboard frame provides structural integrity during installation and service. Rated for airflow up to 1,750 CFM at a maximum face velocity of 500 FPM, this filter handles high-capacity residential and light-commercial air handler applications. Initial resistance is 0.17 inches w.g. at 500 FPM, with a final resistance of 1.0 inch w.g. Licensed HVAC technicians and mechanical contractors are the primary installers.

This filter fits standard 20 x 20 x 4 inch filter housings found in residential forced-air systems, rooftop units, and light-commercial air handlers. At MERV 10, it captures fine dust, pollen, mold spores, and fine particulate matter at a level appropriate for occupied commercial spaces and allergy-sensitive residential environments. The 4-inch depth provides extended filter life compared to 1-inch or 2-inch alternatives, making it well suited for applications where filter change intervals are longer or airflow requirements are higher. It is approved for use with any unit type per manufacturer specifications.

Key Features

• MERV 10 rating with 55% particle capture efficiency per ASHRAE 52.2-2012
• Wire-backed pleated synthetic media maintains pleat geometry under high-velocity airflow
• Nominal 20 x 20 x 4 inches; actual dimensions 19.5 x 19.5 x 3.75 inches for standard housing fit
• 1,750 CFM airflow capacity at 500 FPM maximum face velocity
• Low initial resistance of 0.17 inches w.g. at rated velocity reduces static pressure penalty
• Integrated paperboard frame; rated to 200 degrees F maximum operating temperature
• Listed to UL 900 and compliant with ASHRAE 52.2-2012

Compatibility

Designed for use with any forced-air unit accepting a 20 x 20 x 4 inch filter. The manufacturer specifies compatibility with any unit type.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified mechanical contractors. Always shut down the air handler and confirm the unit is de-energized before removing or installing the filter. Verify the airflow direction arrow on the filter frame aligns with system airflow before seating. Inspect the filter housing for bypass gaps that would allow unfiltered air to pass around the media, and confirm the frame seats flush against the filter rack.
