It uses Polystrand fiberglass media, a continuous-strand material encapsulated in a polymer coating that produces a high-loft filtration layer. Fibers are loosely spun on the air-entering side and progressively woven tighter toward the air-exiting side, creating a graduated density structure. This design increases dust-holding capacity, reduces surface loading, and adds structural strength. The filter carries a MER Value of 4 to 5 and is rated for continuous operation up to 180 degrees F.\u003c\/p\u003e\u003cp\u003eThe TA14251 is suited for standard residential air conditioning units and forced-air HVAC systems that accept a 14 x 25 x 1 inch filter. Its disposable construction makes it appropriate for routine filter replacement programs where low cost per change-out is a priority. The graduated media density is especially effective in applications where dust-holding capacity matters more than high-efficiency particle removal. HVAC service technicians and facility maintenance staff are the primary installers of this filter type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePolystrand fiberglass media with graduated density — loose on the inlet side, tighter on the outlet side — for improved dust-holding capacity\u003c\/li\u003e\n\u003cli\u003ePolymer-encapsulated continuous-strand fibers measuring more than 3.5 microns, classified as nonrespirable\u003c\/li\u003e\n\u003cli\u003eHeavy-duty moisture-resistant white kraft board frame for structural integrity without a metal backing\u003c\/li\u003e\n\u003cli\u003eMER Value 4 to 5 filtration efficiency, suitable for standard particulate capture in comfort-cooling systems\u003c\/li\u003e\n\u003cli\u003eTemperature rated to 180 degrees F continuous and 200 degrees F intermittent\u003c\/li\u003e\n\u003cli\u003eDisposable construction for fast, low-cost replacement service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-size replacement panel filter for residential and light commercial air conditioning units and forced-air systems that accept a 14 x 25 x 1 inch filter slot.

Always shut down the air handler or furnace and confirm the system is de-energized before opening the filter access panel. Insert the filter with the airflow arrow on the frame pointing toward the blower and away from the return air side. Dispose of the used filter in accordance with local waste disposal guidelines and inspect the filter housing for debris before inserting the replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Disposable Panel Air Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia\u003c\/strong\u003e: Fiberglass (Polystrand)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMER Value\u003c\/strong\u003e: 4 to 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 180 degrees F continuous, 200 degrees F intermittent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame\u003c\/strong\u003e: Heavy-duty moisture-resistant white kraft board\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Conditioning Unit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: UL\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AIREX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TA14251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIREX","offers":[{"title":"Default Title","offer_id":51267903848754,"sku":"TA14251","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913912.jpg?v=1780693918","url":"https:\/\/voomisupply.com\/products\/airex-ta14251-fiberglass-panel-air-filter-14x25x1-merv-4-5","provider":"Voomi Supply","version":"1.0","type":"link"}
