It uses Polystrand fiberglass media, which encapsulates continuous glass strands measuring more than 3.5 microns in diameter, making the fibers non-respirable and safer than conventional glass wool media. The filter achieves a MER Value of 4 to 5, offering economical particulate capture suitable for standard air quality maintenance. A heavy-duty, moisture-resistant white kraft board frame holds the media in place and resists deformation in humid conditions.\u003c\/p\u003e\n\u003cp\u003eThis filter is intended for air conditioning units and forced-air HVAC systems where a 20 x 22 x 1 inch filter slot is specified. The Polystrand media is loosely spun on the air-entering side and progressively woven tighter on the air-exiting side, creating a graduated density structure. This design improves dust-holding capacity, reduces surface loading, and adds structural integrity without requiring a metal backing. It is well-suited for applications where high-volume air throughput and low filter resistance are priorities over high-efficiency particulate removal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolystrand fiberglass media with non-respirable fibers greater than 3.5 microns in diameter\u003c\/li\u003e\n  \u003cli\u003eGraduated fiber density from air-entering to air-exiting face increases dust-holding capacity\u003c\/li\u003e\n  \u003cli\u003eMER Value 4 to 5 for standard particulate filtration in residential and light commercial systems\u003c\/li\u003e\n  \u003cli\u003eTemperature rated to 180 degrees F continuous and 200 degrees F intermittent\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty moisture-resistant white kraft board frame for structural stability in humid environments\u003c\/li\u003e\n  \u003cli\u003eUL applicable standard compliance; disposable construction for straightforward replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install disposable panel filter for air conditioning units and forced-air systems requiring a 20 x 22 x 1 inch filter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by HVAC technicians or qualified service personnel. Always shut down the air handler or furnace at the unit disconnect and at the thermostat before replacing the filter. Confirm airflow direction arrows on the filter frame align with the direction of air travel into the system before closing the filter compartment. Inspect the filter housing for bypass gaps that would allow unfiltered air to enter the air handler.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Disposable Panel Air Filter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia\u003c\/strong\u003e: Polystrand Fiberglass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Depth\u003c\/strong\u003e: 1 inch\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: TA20221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIREX","offers":[{"title":"Default Title","offer_id":51268348248370,"sku":"TA20221","price":17.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913888.jpg?v=1780703053","url":"https:\/\/voomisupply.com\/products\/airex-ta20221-fiberglass-panel-air-filter-20x22x1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
