Built with 1mm thick cold-rolled steel and aluminum duct flanges, able to withstand extreme weather. Slide lock door gives easy access to inner chamber while soft neoprene layer creates dust-free seal.

Each air filter box is built using 1mm thick cold-rolled steel and finished with matte black powder coating. This outer body build comes together with aluminum duct flanges to create a sturdy build capable of withstanding inclement weather. Its low-maintenance design features a hinge-sealed door equipped with a slide lock that provides easy access to the inner chamber. The door is lined with a soft neoprene layer that keeps the filter in place, and dust from seeping inside. Applications Each air filter box accepts standard MERV filter replacements that slide into the inner chamber’s filter slot. Comes included with a high-efficacy pleated air filter, capable of trapping 0.3-1.0 micron-sized particles such as: Dust Dirt Lint Odor The duct flanges fit with matching sized 8” inline fans and enable a streamlined installation to create high efficiency filtration in HVAC and grow applications. Attaching the air filter box in the starting end of your ductwork will dramatically reduce suspending particles in the air inside your home. Use with a high static pressure fan like the CLOUDLINE Series of duct fans is highly recommended to ensure maximum filtration. Product Identification Manufacturer AC Infinity Inc.

Review: Like everything AC Infinity makes, it’s extremely high quality. It’s pricey, but I haven’t found something like this on the market. It allows me to filter the air on my air intake. For the exhaust I use a carbon filter and would not use this. It was very easy to instal. The filter size was easy to order replacements for. Highly recommend!!!
Review: Sturdy! I got this after an outside air intake was installed and a large amount of box elder bugs made it into the HVAC system, keeping them toasty inside all winter until they came out the ducts. The company installed a screen that did absolutely nothing. So after digging around to find a solution and found this. Mounted it right after the outside vent, and also put a finer screen on the outside grill as well. Not the bugs and pollen stays out of my ducts and I’m much happier

*by T***M on 25 October 2023*

Used it for a fresh air intake for make up air on a 800 cfm range hood. Just didn’t want to suck on dust from outside. There is a separate exhaust for range hood that’s not in this picture. This is the 8” that requires a 14”x20” filter. Will purchase more of these in future as I need.
