True Blue 112301 Fiberglass Air Filter 12x30x1 Merv 2

Product Description

The TRUE BLUE 112301 is a 1-inch thick fiberglass air filter rated MERV 2, sized 12 inches by 30 inches by 1 inch. It is designed for residential and light commercial forced-air HVAC systems where basic system protection is the primary goal. At MERV 2, this filter captures large airborne particles such as carpet fibers, dust mites, and pollen, keeping debris out of the air handler and blower components. With a service life of up to 30 days, it is a standard disposable replacement suited for high-change-frequency applications or pre-filter setups. HVAC technicians and service pros typically stock these in quantity for routine maintenance calls.

This filter fits ducted forced-air systems using a 12 by 30 by 1 inch filter slot, commonly found in residential furnaces and air handlers. It is appropriate for applications where airflow resistance must be kept low and where filtration demands are minimal. The 30-day replacement interval makes it a practical choice for rental properties, equipment rooms, or any site where low-cost, high-frequency filter changes are standard practice.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel. Set the system thermostat to off and shut down the air handler before removing the old filter. Confirm airflow direction marked on the filter frame aligns with the direction of airflow in the duct or cabinet. Replace at or before the 30-day interval to prevent debris bypass and protect downstream coil and blower components.
