It fits any system that takes a \u003cstrong\u003e20 x 23 x 4\u003c\/strong\u003e filter (20x23x4). This case contains \u003cstrong\u003e6 filters\u003c\/strong\u003e. At a typical 6–12 month change, that is three to six years of filters for one system.\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\u003eP8S4-200-230\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNominal Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20 x 23 x 4\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\u003e6 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. Deeper filters hold far more dust than 1\" filters and typically last 6–12 months, or 3–6 months in homes with pets or heavy dust. Follow your equipment manual if it calls for a different interval. 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":67287801594097,"sku":"KCH-P8S4200230-CS6","price":225.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2657\/5818\/files\/Koch_4in_Filters_6Pk.webp?v=1773584524","url":"https:\/\/hepafiltersales.com\/products\/koch-multi-pleat-xl8-20x23x4-merv-8-air-filter-6-pack","provider":"HEPAFilterSales.com","version":"1.0","type":"link"}
