I've been doing something like this for a while. Four zipties poked through a 20x20 furnace filter attached to a box fan. Price is effectively one air filter (whatever quality you want) and some zipties. Already have plenty of fans sitting around, but they're still cheaper than pretty much any filtration system, and seem to work far better!
