True Blue 114251 Fiberglass Air Filter 14x25x1 Merv 2

Product Description

The TRUE BLUE 114251 is a disposable fiberglass air filter rated MERV 2, sized at 14 x 25 x 1 inch. Designed primarily for system protection, it captures large airborne particles such as dust, lint, and debris before they reach HVAC equipment — blower wheels, heat exchangers, and evaporator coils. At a 1-inch depth, it fits standard residential and light-commercial filter slots without modification. Rated for up to 30 days of service life under normal operating conditions, this filter suits high-turnover maintenance programs where frequent replacement at low cost is the priority. HVAC technicians and property maintenance teams typically stock it in bulk for routine service calls.

This filter is suited for forced-air residential furnaces and air handlers where basic equipment protection is the primary goal rather than fine particulate removal. At MERV 2, it is appropriate for applications with low indoor air quality demands, such as vacant units, storage facilities, light-commercial spaces, or as a pre-filter protecting downstream higher-efficiency filtration. The 14 x 25 x 1 inch nominal size fits a wide range of standard filter grilles and return-air cabinets commonly found in residential and light-commercial systems.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Always set the system thermostat to OFF and confirm the blower has stopped before removing the old filter. Insert the new filter with the airflow direction arrow on the frame pointing toward the blower or air handler. Replace this filter every 30 days or sooner in high-dust environments to prevent airflow restriction and equipment strain.
