That might work for me (not really, I feel the air very different in the woods and around the neighbourhood), but sure won't work in a commieblock jungle.

I think some gas masks use that for filtration so must work. In a home to filter the air it has to be pumped through charcoal it's not enough to have it laying around, ergo some appliance is needed for that. Like or circulator or something. Might not be a bad idea if one has cheap electricity. Maybe a small gadget could be run by a small-ish/portable solar panel. It should be like a tube, sucks the air in one end, and blows out on the other. Maybe two (or even one) cpu fan could do the trick. Slap a replaceable charcoal filter in the middle, enjoy the breeze of the mountains.
I think we are onto something. If we could perfect this thing and make it to production, /kc/ might get rich.
