I had a special similar filter for my HEPA deal on my A/C back in Louisiana, pre-Katrina. I used to order them online; a lot cheaper than local and they delivered quickly. And for the life of me I can't remember the name or find a link (well, it was over two years ago...).
Find the part number on the filter and then put that in a Google search. If you don't find anything at first, put in that part number along with the word filter (e.g., "012345-ABC-678" + filter) and you'll likely find them.
FWIW, I think I changed mine about four to eight times a year, if not more often. They weren't cheap, or at least they weren't as cheap as even the high-filter types you get for a regular A/C filter at the local store (i.e., anywhere from $5 to $25). But we were an active house and we kicked up a lot of dust and dander, apparently, so it got changed more often.
