It uses the same rugged synthetic media engineered for high-velocity and high-moisture air filtration — gas turbine air intakes, marine HVAC, food processing, and humid industrial environments — but with three v-banks of pleats rather than four. Less media surface area trades some service life for a lower price point while keeping the same MERV performance, same incinerable disposal, and same UL Classified construction.\u003c\/p\u003e\u003ch3\u003eWhen DuraMAX 3vS is specified\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCost-conscious high-moisture systems\u003c\/strong\u003e — same synthetic-media performance as the 4vS at a lower price per filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas turbine air intakes\u003c\/strong\u003e — synthetic media stands up to high face velocity and humidity swings without shedding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine, coastal, and humid industrial HVAC\u003c\/strong\u003e — where glass-fiber media historically degrades or sheds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFood processing and pharmaceutical\u003c\/strong\u003e — clean-disposal synthetic in environments with frequent washdowns or sanitation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisposal-sensitive facilities\u003c\/strong\u003e — all-plastic frame is fully incinerable, no metal separation required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign and construction\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia:\u003c\/strong\u003e Dual-layer synthetic, engineered for high-efficiency air filtration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame:\u003c\/strong\u003e All-plastic, lightweight, rigid (incinerable disposal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e 3-bank extended-surface minipleat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency rating:\u003c\/strong\u003e MERV 15 (95% average) per ASHRAE 52.2-2007\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListings:\u003c\/strong\u003e UL Classified per UL Standard 900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReverse-installable:\u003c\/strong\u003e Yes — supports space-limited applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack size:\u003c\/strong\u003e 1 filter per case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat MERV 15 captures\u003c\/h3\u003e\u003cp\u003eVery high-efficiency filtration capturing virtually all sub-micron particles, including fine smoke, bacteria carriers, and most viruses.

For dry, standard-velocity commercial HVAC, the microfiberglass DuraMAX 3v is typically more cost-effective. When in doubt, match what the equipment manufacturer or filter spec sheet calls for.\u003c\/p\u003e\u003ch3\u003e3v vs. 4v: which to choose\u003c\/h3\u003e\u003cp\u003eBoth share the same all-plastic frame, synthetic media, and MERV ratings. The 4vS packs four v-banks of pleats for higher media surface area — lower pressure drop, longer service life, higher initial cost. The DuraMAX 3vS has three v-banks — slightly higher pressure drop, shorter service life, lower initial cost. Choose the 3vS when filter cost matters more than energy savings or extended changeout intervals; choose the 4vS when total cost of ownership matters more.\u003c\/p\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eThe DuraMAX 3vS drops into standard 12″-deep cell-filter housings and is interchangeable with most competitive synthetic-media minipleat filters in the same nominal size. The all-plastic frame and synthetic media also make this a drop-in upgrade for facilities replacing legacy metal-framed glass-fiber filters.\u003c\/p\u003e","brand":"Koch","offers":[{"title":"Default Title","offer_id":44118731620474,"sku":"111-692-402","price":269.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1130\/9462\/files\/nanoclass-cube-3v-pro-membrane_8219b03a-416f-483d-8cc1-21509b1c68ff.jpg?v=1777652795","url":"https:\/\/www.rememberthefilter.com\/products\/20x24x12-koch-duramax-3vs-merv-15-111-692-402","provider":"RememberTheFilter.com","version":"1.0","type":"link"}
