Always power down the air handling unit or furnace at the disconnect or thermostat before replacing the filter. Confirm the airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Check the filter rack or media cabinet for debris before inserting the new filter, and verify the access panel seals properly after installation to prevent bypass air.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 18 x 18 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 17.5 x 17.5 x 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: MERV 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Order\u003c\/strong\u003e: 10 filters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FILTER KING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AF18x18x1-M13\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Filter King","offers":[{"title":"Default Title","offer_id":51716807065906,"sku":"AF18x18x1-M13","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a52058a58898bd868caa4900d6557b74_1d0df6ae-4a14-4443-8d36-30e998aad6fa.jpg?v=1788532169","url":"https:\/\/voomisupply.com\/products\/filter-king-af18x18x1-m13-merv-13-air-filter-18x18x1","provider":"Voomi Supply","version":"1.0","type":"link"}
