Trane FLR6469 Pre-Filter 21" X 25.75" X 1"

The Trane FLR6469 Pre-Filter is a standard 21" x 25.75" x 1" and made to safeguard HVAC systems from large airborne particulate matter such as dust, pollen, and pet dander. HVAC filters with a high efficiency work is that they entrap these particles so that they will not be able to get through and harm internal components of the HVAC system that may already be susceptible to dirt. This component assists in enhancing the accents within structures which consequently raises the indoor air quality, energy use efficiency, and duration of the HVAC system.
