True Blue 112201 Fiberglass Air Filter 12x20x1 Merv 2

Product Description

The TRUE BLUE 112201 is a 12 x 20 x 1 inch disposable fiberglass air filter rated MERV 2, designed for standard residential forced-air HVAC systems. At MERV 2, it captures large airborne particles such as carpet fibers, dust mites, and pollen, providing baseline system protection by keeping debris off blower wheels, heat exchangers, and coil surfaces. Each filter is rated for up to 30 days of service under normal operating conditions. HVAC technicians and homeowners in light-maintenance environments install this filter as a cost-effective, high-airflow option where filtration efficiency is less critical than system airflow and equipment protection.

This filter is suited for residential and light-commercial forced-air applications where low static pressure drop is a priority. Typical install scenarios include rental units, vacation properties, and second-stage pre-filter positions. Its fiberglass media allows high airflow rates, making it appropriate for older systems with weaker blower motors or ductwork with marginal sizing. The 12 x 20 x 1 inch form factor fits a wide range of standard filter slots in air handlers and furnace return-air compartments.

Installation Notes

A licensed HVAC technician or qualified homeowner can replace this filter with the system power on, though powering down the air handler before servicing the filter compartment is recommended practice. Verify airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Replace every 30 days or sooner in high-dust environments. Do not operate the system without a filter installed, as unfiltered air can deposit debris on coil surfaces and blower components.
