{"product_id":"18x24x2-air-filter","title":"18x24x2 Aerostar Air Filter","description":"The 18x24x2 Aerostar comes in at 17 3\/8\" x 23 3\/8\" x 1 3\/4\" actual. Built for a nominal 18x24x2 return, which is a common spec on older residential furnaces and many light commercial air handlers. The 2-inch depth gives you roughly twice the debris-holding capacity of a 1-inch filter in the same nominal opening, and the lower pressure drop is easier on the blower motor across its service life. MERV 8 covers standard residential dust and pollen filtration. MERV 11 handles pet dander and most common allergens. MERV 13 captures fine particulates including smoke, bacteria, and virus-carrying droplets - the right grade if the household has someone with asthma or if wildfire smoke is a regular concern. Pleated synthetic media with an electrostatic charge does the filtration work. Manufactured in the USA by Con-Air Industries at the Orlando, Florida facility. The cardboard frame is reinforced to maintain shape under the suction generated by modern variable-speed blowers, which run at higher airflow rates than older single-stage units. Service life is 4 to 6 months for MERV 8 and 11 in typical residential conditions, 2 to 4 months for MERV 13. Heavier load conditions shorten those intervals proportionally.","brand":"Aerostar","offers":[{"title":"MERV 8 \/ 6","offer_id":41902634074266,"sku":"P80S.021824-6","price":90.0,"currency_code":"USD","in_stock":true},{"title":"MERV 11 \/ 2","offer_id":41902633910426,"sku":"P15S.021824-2","price":67.8,"currency_code":"USD","in_stock":true},{"title":"MERV 13 \/ 2","offer_id":41902633943194,"sku":"P25S.021824-2","price":68.08,"currency_code":"USD","in_stock":true},{"title":"MERV 8 \/ 4","offer_id":41902633975962,"sku":"P80S.021824-4","price":76.4,"currency_code":"USD","in_stock":true},{"title":"MERV 11 \/ 4","offer_id":41902634008730,"sku":"P15S.021824-4","price":96.88,"currency_code":"USD","in_stock":true},{"title":"MERV 13 \/ 4","offer_id":41902634041498,"sku":"P25S.021824-4","price":109.2,"currency_code":"USD","in_stock":true},{"title":"MERV 8 \/ 2","offer_id":41902633877658,"sku":"P80S.021824-2","price":59.04,"currency_code":"USD","in_stock":true},{"title":"MERV 11 \/ 6","offer_id":41902634107034,"sku":"P15S.021824-6","price":130.44,"currency_code":"USD","in_stock":true},{"title":"MERV 13 \/ 6","offer_id":41902634139802,"sku":"P25S.021824-6","price":153.12,"currency_code":"USD","in_stock":true},{"title":"MERV 8 \/ 12","offer_id":41902634172570,"sku":"P80S.021824-12","price":165.84,"currency_code":"USD","in_stock":true},{"title":"MERV 11 \/ 12","offer_id":41902634205338,"sku":"P15S.021824-12","price":239.4,"currency_code":"USD","in_stock":true},{"title":"MERV 13 \/ 12","offer_id":41902634238106,"sku":"P25S.021824-12","price":282.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0591\/6937\/4362\/files\/18x24x2_MERV8_6pk.png?v=1788227302","url":"https:\/\/myairfiltersdeliveredeals.com\/products\/18x24x2-air-filter","provider":"Air Filters Delivered","version":"1.0","type":"link"}
