Thanks! I was probably going to use one of these or these. I'm thinking building a duct and sending air through one 20x25 filter for each wall unit, and also for my air intake. Really sure how it will affect the units, although I was thinking I could add a boost fan later where needed.
...or maybe this one: better MERV

Nov. 4 Update::::::::::::::::::::::::::::::::::::::::::::::::::::::
Ok, I've made some tentative new progress fixing my problem. I've basically decided I need to rebuild my crawlspace, and perhaps expand it in the process. I've come to realize that I think the vapor barrier was ripped when I had my initial problems with the groundhog, and at this point, doing a patch fix will be a major pain, and perhaps not good enough. Also I think some of the other groundhog proofing that was done DIY is probably causing some extra wood rot problems, and really should be removed. So I've come up with the plan to tear up the old crawlspace, and build a new one that goes the full width of the building, in the process installing a new vapor barrier, and adding a couple extra features to help with pest-proofing. In the end I should be left with a new 8'x25' tall crawlspace.
I've been in touch with a few contractors at this point, and have had a couple out to look at the site. I had one guy was obviously just trying to talk up the price, I was not able to get a quote from the other. I tried to get a quote from the concrete supplier although they couldn't quote me without a final plan. (I'm probably leaning more toward getting some handymen types to help me, at this point, as my initial contractor interactions have been mediocre to bad). In the mean time I've been looking into what materials I need. I went and bought some heavy duty plastic from Lowes the other day, and my roll of vapor-barrier-seam-tape just arrived today. I'm also thinking of getting a portable cement mixer, incase I decide to the project with bags(probably much cheaper that way). My local concrete supplier did provide some interesting ideas however about details/best-practices of doing the job: basically that it is a 2 part job, with a poured foundation, and then a masonry wall on top. Below is some "napkin math": I think I can probably get all of the materials for less than $2k, not including tool rentals(cement-pump, mixer, picks&shovels).
Pump trailers are not cheap: looks like the average cost to own is $30k-$50, although I guess it's just a question of how much a contractor would charge on the job. Also, I'm not sure if I actually need a pump, although pouring from the truck might be difficult(actually leaning more towards bags and a mixer at this point).
I'm still not sure about exactly what we want to do about the back wall. Does it need a back wall? part of the problem i'm trying to fix was that groundhogs dug around behind the old wall, and came in, ripping the plastic in the process. thinking perhaps I could do something clever with pavers on the outside to discourage this. and then there is the difficult quesiton of how to make the new plastic vapor barrier seamless with the old? looks like I've got my work cut out for me ;P
