It fits any system that takes a \u003cstrong\u003e19 x 21 x 1\u003c\/strong\u003e filter (19x21x1). This case contains \u003cstrong\u003e12 filters\u003c\/strong\u003e. At a quarterly change, that is three years of filters for one system, or one year for three systems.\u003c\/p\u003e\n\u003cp\u003eMulti-Pleat XL8 uses 100% mechanical filter media, so its efficiency does not depend on an electrostatic charge that can fade over time. A galvanized expanded-metal support grid is laminated to the media to hold the pleats in shape, the pleats are bonded to the frame to prevent air bypass, and the double-wall, moisture-resistant beverage-board frame with reinforced corners stays rigid in humid conditions.\u003c\/p\u003e\n\u003ch3\u003eIs This the Right Size?\u003c\/h3\u003e\n\u003cp\u003eAir filters are sold by \u003cstrong\u003enominal size\u003c\/strong\u003e, the rounded size printed on the frame of your current filter. The filter itself is made slightly smaller so it slides into the filter slot — typically about 1\/2\" under nominal on length and width, and 3\/4\" deep for a 1\" filter. Match the nominal size printed on your old filter, not a tape measurement of the slot.\u003c\/p\u003e\n\u003cp\u003eNot sure? \u003ca href=\"\/pages\/contact-us\"\u003eSend us a photo of the label on your current filter\u003c\/a\u003e and we will confirm the match before you order.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eKoch Filter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMulti-Pleat XL8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eKoch Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eP8S1-190-210\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNominal Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e19 x 21 x 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMERV Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMERV 8 | MERV-A 8 (ASHRAE 52.2-2007)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMedia\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100% mechanical synthetic media\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMedia Support\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGalvanized expanded metal, laminated to media\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrame\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDouble-wall moisture-resistant beverage board, reinforced corners\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12 filters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat MERV 8 Captures\u003c\/h3\u003e\n\u003cp\u003eMERV 8 is the everyday standard for residential systems. Under ASHRAE 52.2 a MERV 8 filter captures at least 70% of particles in the 3–10 micron range (household dust, lint, pollen, dust mite debris and mold spores) while keeping airflow resistance low enough for virtually any furnace or air handler.\u003c\/p\u003e\n\u003ch3\u003eReplacement Schedule\u003c\/h3\u003e\n\u003cp\u003eCheck the filter monthly and replace it at least every three months — sooner in homes with pets, during renovation work, or whenever it looks loaded with dust. Install it with the airflow arrow on the frame pointing toward the blower.\u003c\/p\u003e\n\u003cp\u003eIn commercial systems, change the filter when pressure drop across it reaches 1.0\" w.g., Koch's recommended final resistance for this filter.\u003c\/p\u003e\n\u003cp\u003eShop all \u003ca href=\"\/collections\/koch\"\u003eKoch Filter air filters\u003c\/a\u003e.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Koch Filter","offers":[{"title":"Default Title","offer_id":67287786619121,"sku":"KCH-P8S1190210-CS12","price":293.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2657\/5818\/files\/Koch_Filter_Twelve.jpg?v=1765124469","url":"https:\/\/hepafiltersales.com\/products\/koch-multi-pleat-xl8-19x21x1-merv-8-air-filter-12-pack","provider":"HEPAFilterSales.com","version":"1.0","type":"link"}
