{"product_id":"18x18x2-air-filter","title":"18x18x2 Aerostar Air Filter","description":"The 18x18x2 Aerostar measures 17 1\/2\" x 17 1\/2\" x 1 3\/4\" actual, sized for a nominal 18x18x2 slot. A 2-inch filter in this nominal size holds substantially more debris than a 1-inch equivalent and runs at lower pressure drop, which extends both service life and blower lifespan. MERV 8 handles standard residential filtration. MERV 11 covers pet households and mild allergy concerns. MERV 13 captures fine particulates including smoke, bacteria, and virus-sized aerosols. The deeper pleat depth makes higher MERV grades more practical: pressure drop falls as filter depth increases, so MERV 13 in a 2-inch is significantly easier on the system than MERV 13 in a 1-inch. Pleated synthetic electrostatic media handles the filtration. Cardboard frame, reinforced for shape retention under suction. Manufactured by Con-Air Industries in Orlando, Florida. Expect a 4-to-6-month service life on MERV 8 and 11 in typical residential conditions, 2 to 4 months on MERV 13 under similar load. Heavy-load conditions - multiple pets, active cooking, smoke events - shorten those intervals regardless of grade. If you're moving from a 1-inch fiberglass to this 2-inch pleated unit, expect a noticeable improvement in both filtration performance and the time between changes.","brand":"Aerostar","offers":[{"title":"MERV 8 \/ 6","offer_id":41902624571546,"sku":"P80S.021818-6","price":119.99,"currency_code":"USD","in_stock":true},{"title":"MERV 11 \/ 2","offer_id":41902624374938,"sku":"P15S.021818-2","price":51.47,"currency_code":"USD","in_stock":false},{"title":"MERV 13 \/ 2","offer_id":41902624440474,"sku":"P25S.021818-2","price":65.42,"currency_code":"USD","in_stock":false},{"title":"MERV 8 \/ 4","offer_id":41902624473242,"sku":"P80S.021818-4","price":75.99,"currency_code":"USD","in_stock":false},{"title":"MERV 11 \/ 4","offer_id":41902624506010,"sku":"P15S.021818-4","price":100.88,"currency_code":"USD","in_stock":false},{"title":"MERV 13 \/ 4","offer_id":41902624538778,"sku":"P25S.021818-4","price":109.2,"currency_code":"USD","in_stock":false},{"title":"MERV 8 \/ 2","offer_id":41902624342170,"sku":"P80S.021818-2","price":49.99,"currency_code":"USD","in_stock":false},{"title":"MERV 11 \/ 6","offer_id":41902624604314,"sku":"P15S.021818-6","price":146.68,"currency_code":"USD","in_stock":true},{"title":"MERV 13 \/ 6","offer_id":41902624637082,"sku":"P25S.021818-6","price":153.12,"currency_code":"USD","in_stock":true},{"title":"MERV 8 \/ 12","offer_id":41902624669850,"sku":"P80S.021818-12","price":229.99,"currency_code":"USD","in_stock":true},{"title":"MERV 11 \/ 12","offer_id":41902624702618,"sku":"P15S.021818-12","price":277.93,"currency_code":"USD","in_stock":true},{"title":"MERV 13 \/ 12","offer_id":41902624735386,"sku":"P25S.021818-12","price":282.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0591\/6937\/4362\/files\/18x18x2_MERV8_6pk_c6a12592-0ab0-4301-91b5-7cf86bccff77.png?v=1788212541","url":"https:\/\/myairfiltersdeliveredeals.com\/products\/18x18x2-air-filter","provider":"Air Filters Delivered","version":"1.0","type":"link"}
