Ruck 14 inch Intake Filter Box | MERV 5 Mat, Galvanized Steel

Inside the 14 Inch Intake Filter Box The largest box in the range, for 14 in intake duct. Housing is galvanized sheet steel at 19.9 x 20 x 7.8 in and 11 lbs. The media is an ISO Coarse 45% / MERV 5 fiber mat, coarse on purpose so that a large intake keeps its airflow. Servicing the MERV 5 Intake Filter Toggle fasteners give tool-free access for mat changes, on a three to six month interval. At that weight, plus the duct hanging off it, support the box on its own fixings rather than letting the ductwork carry it. It is worth knowing what the box leaves alone: this is coarse filtration on the intake, so exhaust odour is still a carbon filter's job. A loaded mat costs airflow, so look at it rather than assuming. Leave clearance in front of the lid, because at this size the mat is awkward to angle out. A quick look each month tells you more than any fixed schedule. Key Features ISO Coarse 45% / MERV 5 Mat: Coarse on purpose, so it traps debris without strangling the intake. Galvanized Steel Housing: Holds its shape and resists corrosion in a damp intake path. Toggle Fastener: Opens without tools, so mat changes take about a minute. 3 to 6 Month Mat Life: A realistic interval, shorter in a dusty or high-pollen space. Recyclable Mat: The media can be recycled rather than binned. 14 in Duct Fit: Sized for Ruck 14 in components and standard 14 in duct.
