For a while I just used a big HEPA air purifier attached to a clear plastic crate through terribly-sawn openings. It was very positive pressure: light items would be blown out! But, it worked well until one day it didn't; I believe the filter was finally saturated.
In my experience, then, a good pos-pressure hood is trivial and mobile, but I use a bunsen exclusively these days.

What is the cheapest and cleanest way to make a work hood that at

while on?
I know the big panel filters are at least $100-150 USD, and a copper
or stainless grating is probably a good (but not cheap) idea for a
vent to protect the filter or cover the air duct.
