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 V-Bank Style is configuration-specific — this SKU is matched to the 4V version of the DuraMAX. Choose V-Bank when you want the maximum prefilter media area and longest prefilter service life. If your facility runs both 3v and 4v final filters, you'll need both V-Bank SKUs (or the universal Cube Style).\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":44118773530746,"sku":"111-599-001","price":493.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1130\/9462\/files\/getimage2_88663d18-7b7b-4348-a3c6-eca4d098a3ae.png?v=1777658444","url":"https:\/\/www.rememberthefilter.com\/products\/24x24x12-koch-duraglove-v-bank-4v-prefilter-111-599-001","provider":"RememberTheFilter.com","version":"1.0","type":"link"}
