I wonder where one would buy large quantities of thin aluminum c-channel of a dimension suitable for holding filters. With a hacksaw and miter box, it would be straightforward to construct frames for your preferred size of filter. Then the frames could be taped together, instead of taping the filters themselves, constructing basically the thing you would like to buy. Some enterprising individual with a band saw and drill press could make custom filter frame kits if people use varying sizes of filter.
Did you choose the filter size in this project based on cost efficiency, or for compatibility with other appliances in your home, or based on some other metric? When I do things with filters, I like using the same size that my HVAC takes, because then any extras can go in the whole-house fan rather than risking them going to waste. I assume that others might choose filters the same way, but I realize that I’ve never actually asked. This seems to matter because if everyone uses the same size filters and fans, mass producing the frame kits would make sense, but if folks want to retrofit existing fans with filters that match their other home applications, custom building kits would likely be preferable.
The other option would be make a drawing and then go talk with a local HVAC company to see if they make their own custom duct work or if they have a supplier they will introduce you to.
I chose 12“ because that’s how far my fan blades are from the ceiling and I didn’t want to lose headroom. I chose 12x20 because that seemed to be the cheapest size per area for 12” merv-14 filters.
I don’t have an HVAC system that uses a filter, so I don’t have something to match.

Something like this https://www.metalsdepot.com/aluminum-products/aluminum-channel-6063? 1/16″ is perhaps overkill for this type of application—but then perhaps having it provide some structural strength is a good thing.
