Another Medik-Aire link...
Here is another link to the Medik-Aire, but this one is on the same site that Erik provided for the homemade-looking filter. Curious that the home website for it is www.air-storm.com. Is this website officially tied to the Patriot company? If so, could the homemade-looking filter be any good? Even at $45 it's a lot less expensive than the Medik-Aire. And actually not that much more than the Filter Fresh, which folks so far dislike. The question is, is the filter actually any good?
It's curious that the two Medik-Aire filters look different on the two sites. One has a foam filter around the circumference, of course, but they still look slightly different.
