Product Description

25" x 25" x 1" nominal furnace/return air filter — a ready-fit residential HVAC panel available in disposable fiberglass and pleated medias and a range of efficiencies (common MERV 8, 11 and 13 options). Catalog listings show actual finished thickness can be slightly under the nominal 1" (many pleated 25x25x1 filters are listed with actual dimensions around 24.5–24.75" square and 3/4"–3/4" thickness), so confirm the return opening before sale. Pleated MERV 8/11/13 variants are marketed for 90-day typical service life and broad compatibility with furnaces, central ACs, heat pumps and return grilles, while basic fiberglass “throwaway” panels offer lower efficiency at a lower price point. Current retailer listings show per-filter retail equivalents running from about $9.67 each (6‑pack pleated per‑filter math) up through roughly $24–$25 each (specialty/12‑pack exact pleated MERV 13 units), with fiberglass single-item listings around $16 each — based on the cited product pages below. For a single 25" x 25" x 1" filter sold individually in Dayton, IA 50530, a competitive resale price for a standard pleated (MERV 8) panel would be approximately $12.99 each (this undercuts many big‑box single-item prices while leaving room for a modest resale margin; charge more for higher‑MERV pleated or branded exact‑fit filters).
