True Blue 120241 Fiberglass Air Filter 20x24x1 Merv 2

Product Description

The TRUE BLUE 120241 is a 20 x 24 x 1 inch fiberglass air filter rated MERV 2, designed for use in residential and light commercial forced-air HVAC systems. At MERV 2, this filter provides baseline system protection by capturing large airborne particles such as dust, lint, and carpet fibers before they reach the blower and heat exchanger. The filter has a service life of up to 30 days under normal operating conditions, making it well-suited for high-turnover replacement programs or budget-conscious maintenance schedules. HVAC technicians and property maintenance professionals typically keep these on hand in bulk for routine filter change-outs.

This filter is intended for installations where airflow efficiency and equipment protection take priority over fine particulate capture. Typical applications include return-air filter grilles, air handlers, and furnace filter slots in residential homes, apartments, and light commercial spaces. The 20 x 24 x 1 inch nominal size fits a wide range of standard filter housings. A 30-day replacement interval supports scheduled preventive maintenance visits.

Installation Notes

Filter installation and replacement is typically performed by HVAC technicians or qualified maintenance personnel. Always shut down the air handler or furnace at the disconnect or thermostat before removing or installing a filter. Verify airflow direction arrows on the filter frame align with the direction of airflow into the blower. Replace the filter at or before the 30-day interval to prevent dust bypass and coil fouling.
