Pro-source PRO21919271 Pleated Air Filter 19x27x1 Merv 8

Product Description

The PRO-SOURCE PRO21919271 is a MERV 8 pleated air filter designed for residential and light commercial HVAC systems. It uses a synthetic media construction housed in a clay coated paperboard frame with an integrated support structure. Rated at 1,336 CFM, this filter handles moderate air volumes across a wide range of air handling equipment. At a nominal size of 19 x 27 x 1 inches, it fits standard filter slots and delivers reliable particulate capture at an initial resistance of 0.19 inches water gauge at 300 FPM and 0.26 inches water gauge at 375 FPM. Licensed HVAC technicians and building maintenance professionals are the primary installers.

This filter is suitable for forced-air heating and cooling systems in residential homes, apartments, and light commercial buildings. The MERV 8 rating makes it appropriate for environments where moderate filtration of dust, pollen, mold spores, and similar airborne particles is required without significantly restricting airflow. It is rated for use with any unit, making it a versatile stock replacement filter for a broad range of air handlers, furnaces, and fan coil units. The maximum operating temperature is 150 degrees F, which is within the range of most standard forced-air equipment.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Always shut down the air handler or furnace at the disconnect or breaker before removing or installing the filter to prevent unfiltered air bypass and protect blower components. Confirm airflow direction arrows on the filter frame align with the direction of airflow in the unit. Dispose of used filters in accordance with local regulations, as collected particulates may contain allergens or fine debris.
