The 4v packs four v-banks of pleats for higher media surface area — lower pressure drop, longer service life, higher initial cost. The 3v has three v-banks — slightly higher pressure drop, shorter service life, lower initial cost. Choose the 3v when filter cost matters more than energy savings or extended changeout intervals; choose the 4v when total cost of ownership matters more.\u003c\/p\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eThe DuraMAX 3v drops into standard 12″-deep cell-filter housings and is interchangeable with most competitive minipleat filters in the same nominal size. For systems that previously used metal-framed rigid cells, the all-plastic DuraMAX is a direct upgrade with simplified end-of-life disposal.\u003c\/p\u003e","brand":"Koch","offers":[{"title":"Default Title","offer_id":44118729556090,"sku":"111-601-403","price":429.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1130\/9462\/files\/nanoclass-cube-3v-pro-membrane_fd0767f3-4b75-4880-8c44-d34e052d9a30.jpg?v=1777652406","url":"https:\/\/www.rememberthefilter.com\/products\/12x24x12-koch-duramax-3v-merv-14-111-601-403","provider":"RememberTheFilter.com","version":"1.0","type":"link"}
