Trane FLR1486 Permanent Filter 16.5" X 25" X 1"

The Trane FLR1486 is a Permanent Air Filter that is designed for use with Trane heating and cooling systems, of which air conditioners and furnaces are the most popular. It comes in the size 16.5” by 25” by 1” though some of the sites we visited indicated that this size was slightly different and that it was 24.8” x 16.62” x 1”. The cleaning system demands it because it traps dust, allergies, and any other particles that may be within the air when it flows through the system. As for the differences, while they are the opposite of disposable filters, they can be used again.
