That orientation creates a natural surface for an upstream sleeve. The DuraGlove fits over that surface and absorbs coarse particulates before they load into the more expensive minipleat media. Spring clips that already secure the DuraMAX hold the DuraGlove in place — no additional hardware, no housing modifications.\u003c\/p\u003e\u003ch3\u003eCube vs. V-Bank style\u003c\/h3\u003e\u003cp\u003eThe Cube Style is the universal option — it sleeves over the entire face of the DuraMAX regardless of whether the underlying filter is a 3v or 4v configuration. Choose Cube when you want one prefilter SKU that fits across mixed final-filter inventory, or when you don't need the maximum prefilter media area of the V-Bank format.\u003c\/p\u003e\u003ch3\u003eImportant: this is a prefilter, not a final filter\u003c\/h3\u003e\u003cp\u003eThe DuraGlove is designed to work upstream of a high-MERV final filter, not in place of one. It does not carry a published MERV rating because it isn't intended to be the primary particle-capture stage. Specify a Koch DuraMAX (4v, 4vS, 3v, 3vS, or 2v) at the appropriate MERV rating for your application, then add a DuraGlove to extend the final-filter's life.\u003c\/p\u003e","brand":"Koch","offers":[{"title":"Default Title","offer_id":44118773432442,"sku":"111-599-004","price":274.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1130\/9462\/files\/getimage2_d814367f-7a71-4d1d-92f3-2dcabc93aa55.png?v=1777658428","url":"https:\/\/www.rememberthefilter.com\/products\/24x24x12-koch-duraglove-cube-prefilter-111-599-004","provider":"RememberTheFilter.com","version":"1.0","type":"link"}
