Trane ag0450239 Pleated Air Filter 14x20x2 Merv 10

Product Description

The TRANE ag0450239 is a wire-back pleated air filter rated MERV 10 for standard-capacity residential and light commercial HVAC systems. It uses a synthetic media construction backed by a rigid wire support structure that maintains pleat geometry under varying airflow conditions. The moisture-resistant beverage board frame resists deformation in humid operating environments. At an actual size of 13.5 inches wide by 19.5 inches tall by 1.75 inches thick, it fits nominal 14x20x2 filter housings and is sold in cases of 12 units. MERV 10 filtration captures fine dust, pollen, mold spores, and pet dander, making it a reliable upgrade over standard fiberglass media.

This filter is suited for split systems, air handlers, and gas furnaces equipped with a nominal 14x20x2 filter slot. It is appropriate for residential applications where improved indoor air quality is a priority without a significant static pressure penalty. The MX40 series designation indicates standard capacity and standard size in the TRANE filter lineup. HVAC technicians commonly stock this filter for preventive maintenance agreements on residential equipment with standard-size return-air filter racks.
