I did some searching for suppliers of pleated filters. Of course the current gold standard is the Wynn, reasonably priced at $200. I saw references to using large diesel truck air filters, so I did some searching down that path, but got nowhere. I found a company, Killer Filter who makes filters, so I called them to see what they could do. I showed them Wynn's page. they said... let me get back to you. what they came back with is their brand new (since my inquiry) model 114-7449.
it is less stuff than the Wynn in that it is the filter only- no hold down hardware or lid, but that stuff is easily enough fabricated by woodworkers who are willing to tinker with their dust collectors. for me, the price difference is worthwhile. I ordered it. when it comes in I'll report back.
disclaimer:
I don't work for Killer Filter, Yadda yadda. just found what looks like a good deal.

Thanks for starting this thread Bridger.
I have also looked for alternatives and read about someone using heavy truck air filters (the are similar in size to what we need). In my pursuit I came across Donaldson Torit P190817-016-436 or P190818-016-436. These filters have a13.84-inch outer diameter and a 26.00-inches length, with a 2.00-inch pleat height. Open at both ends with rubber gaskets with a continuous outer layer of 0.2-0.3 micron . I bought 2 from ebay for $80 or less in the past year. I also came across this supplier (https://www.systech-design.com/product/donaldson-torit-p190817-016-436/) who sells them new for $89. It appears these are actual Donaldson filters as many filter suppliers (like Killer Filter) make equivalent parts that fit the original manufacturers part, but are not original manufacturer parts. I have never ordered from systech, but they seem to have the best price for those models.
Hope that also helps with an alternative
