Pro-source PRO21270 Pleated Air Filter 20x25x2 Merv 8

Product Description

The PRO-SOURCE PRO21270 is a MERV 8 pleated air filter designed for residential and light commercial HVAC systems requiring standard panel filtration. Measuring 20 x 25 x 2 inches nominal (19.5 x 24.5 x 1.75 inches actual), it uses a synthetic wireform-free pleated media housed in a paperboard frame. At a MERV 8 rating with 35% particle capture efficiency per ASHRAE 52.2-2012, it captures common airborne particles including dust, pollen, and lint. Rated for airflow up to 1,750 CFM at a maximum face velocity of 500 feet per minute, it delivers reliable performance across a wide range of air handler and furnace configurations. Licensed HVAC technicians and facilities maintenance personnel handle routine installation.

The PRO21270 fits standard 20 x 25 x 2 inch filter slots found in residential forced-air furnaces, central air handlers, and packaged HVAC units. Its synthetic pleated media construction is rated for operating temperatures up to 150 degrees F, making it suitable for return-air filter applications in both heating and cooling seasons. The integrated paperboard frame provides structural stability during installation and operation, maintaining pleat geometry under normal duct static pressure conditions.

Installation Notes

HVAC technicians and maintenance personnel install this filter. Always set the system thermostat to the off position and confirm the air handler or furnace blower has stopped before replacing the filter. Verify the airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Inspect the filter housing for bypass gaps and ensure the frame seats flush against all four sides of the track before restoring system operation.
