Flanders PrecisionAire Cut-To-Fit 24x36x1 Natural Fiber Air Filter

Overview

The Flanders PrecisionAire 40655.012436 is a NaturalAire cut-to-fit air filter designed for flexible 1-inch depth slots. The material feels springy and almost rigid, helping it hold its shape without needing a separate frame. With standard heavy shears or a razor knife, you can create a custom 1-inch size for most furnace and central‑air installations. An added practical detail: the filter can be washed and reused, making it a dependable option when exact sizes are hard to source.
