WOW! I think that filter looks great. I would think the way those pleats are folded would absolutely keep them in place and keep everything spaced nicely. If those were readily available to us here (at a reasonable price) I would consider using them. Not that I have any problems with the XG's I use currently.
I would like to see how they connected the material at the seam.
