I want to scrub the exhaust air but also filter the incoming air. I'm doing it in a basement and I dont like how it smells down there sometimes. I just edited the post for clarity sorry if i left anything out
i think im going to try the 8x12 (460cfm) because its only $62 on amazon. phuck it! phresh filter it is!
i basically just dont want too much negative pressure and my tent sucking in at the seams, if the filter is way over sized i dont think it can hurt. i have a mini tent i can also feed with it.
anyone here build a furnace filter box? ill pay the 60 for now until i can build myself a good box filter
