^^ I tried the Alten Brown box fan jerky before I had a house w/ a patio that could accommodate a smoker and a BBQ grill.
I tried to make some beef and buffalo jerky. I think the whole endeavor put me back around 80 bucks after buying meat, missing spices, fan, and filters. I followed the directions precisely and in the end I ended up with a whole bunch of ruined jerky! It stuck to the paper of the filters and I only rescued about 1/4 of the finished amount. What a phenomenal waste of money. I think you'd be better off using your oven and a mesh screen or buying a dehydrator if you don't have any other means.
I for one will not be heading down that path again. I will, however, be making jerky on the smoker in the next couple of weeks... qview coming soon.
At least I got a box fan out of the deal though
