Replace it every three to six months. Because a box this size is heavy, hang it on its own support rather than letting the duct carry it. The mat handles particles only; odour control stays with the exhaust carbon filter. Watch the pressure drop as it loads, since at 12 in a clogged mat costs real airflow. Mount it where the lid can swing clear, otherwise servicing turns into a two-person job.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Coarse 45% \/ MERV 5 Mat:\u003c\/strong\u003e Coarse on purpose, so it traps debris without strangling the intake.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanized Steel Housing:\u003c\/strong\u003e Holds its shape and resists corrosion in a damp intake path.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToggle Fastener:\u003c\/strong\u003e Opens without tools, so mat changes take about a minute.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 to 6 Month Mat Life:\u003c\/strong\u003e A realistic interval, shorter in a dusty or high-pollen space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecyclable Mat:\u003c\/strong\u003e The media can be recycled rather than binned.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 in Duct Fit:\u003c\/strong\u003e Sized for Ruck 12 in components and standard 12 in duct.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eDuct Size\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e12 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFilter Class\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eISO Coarse 45% (G3) \/ MERV 5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eHousing\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eGalvanized sheet steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFastener\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eToggle type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eDimensions (L x H x W)\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e19.9 x 20 x 7.8 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e13.4 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFilter Replacement\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eEvery 3 to 6 months\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Ruck Air Movement","offers":[{"title":"Default Title","offer_id":47033455935702,"sku":"149455","price":166.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/ruck-intake-filter-box-1050-v1_8a6646c5-88ba-4ffa-9e49-d0c3f9e2ee4e.webp?v=1788972190"},{"product_id":"ruck-14-intake-filter-box","title":"Ruck 14 inch Intake Filter Box | MERV 5 Mat, Galvanized Steel","description":"\u003ch2\u003eInside the 14 Inch Intake Filter Box\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe largest box in the range, for \u003cstrong\u003e14 in\u003c\/strong\u003e intake duct.

It is exclusion, not filtration, and at this diameter that distinction matters more, because fine mesh would cost measurable pressure. Sweep the face clear each season. It seats on a matching Ruck collar without adaptors. This is a mechanical guard and not part of the pressure envelope, so do not expect it to seal anything.

On a 14 in installation that is the difference between a service job and a rebuild. The isolating seal handles vibration through the joint, not air noise, so a silencer remains a separate item. Because the neoprene compresses as it beds in, go back and re-check the tension after a few weeks of running.

Put it downstream of the fan with the flaps opening the way the air goes. The honest cost is a small static pressure penalty, which on an 8 in run is usually irrelevant but is real. Check the rubber seat for dust when you service the fan; that is what makes a damper leak. If the flaps chatter at low speed, the fan is running below the pressure they need to stay open.

Ruck suggests replacing every three to six months, and in a dusty room it will be the shorter end of that, with the used media recyclable rather than binned. What the box gives you is intake filtering rather than odour control, so a carbon filter still belongs on the exhaust. Budget for a small pressure drop as well, which grows as the mat loads. Fit it before the intake reaches any fan, so nothing abrasive gets to the impeller.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Coarse 45% \/ MERV 5 Mat:\u003c\/strong\u003e Coarse on purpose, so it traps debris without strangling the intake.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanized Steel Housing:\u003c\/strong\u003e Holds its shape and resists corrosion in a damp intake path.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToggle Fastener:\u003c\/strong\u003e Opens without tools, so mat changes take about a minute.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 to 6 Month Mat Life:\u003c\/strong\u003e A realistic interval, shorter in a dusty or high-pollen space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecyclable Mat:\u003c\/strong\u003e The media can be recycled rather than binned.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4 in Duct Fit:\u003c\/strong\u003e Sized for Ruck 4 in components and standard 4 in duct.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eDuct Size\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFilter Class\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eISO Coarse 45% (G3) \/ MERV 5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eHousing\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eGalvanized sheet steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFastener\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eToggle type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eDimensions (L x H x W)\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e8.1 x 8.1 x 7.8 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eFilter Replacement\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eEvery 3 to 6 months\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Ruck Air Movement","offers":[{"title":"Default Title","offer_id":47033464422614,"sku":"149448","price":76.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/ruck-intake-filter-box-1050-v1.webp?v=1788972110"}],"url":"https:\/\/growershouse.com\/collections\/ducting.oembed?page=2","provider":"GrowersHouse","version":"1.0","type":"link"}
