Cleaning Intake Air Coming From Outside

If any of you guys draw your intake air from outside your home what do you use to filter it before it goes into your tent to avoid bringing any pathogens or insects into your home/tent?

I don't use anything the window screen dose alot already

There's no screen on my window, there's a piece of wood with 2 holes sawed in it to accommodate the exhaust fan and intake fan.

I use a piece of farbic I bought at walmart, it is the same consistencies as a butterfly net.

ducting screen they come with carbon filter pad

Local hardware store...buy sheet furnace filter material..the kind like plastic fires...cut to size and attach to inside end.
Women's pantyhose works well too.

+1 for stockings/pantyhose lol.

If your drawing from outside you want a furnace filter at least. Preferably a HEPA and a furnace filter. Pollen will go right through panty hose.

I have some MERV12 furnace filter I cut and use for these DIY intake's I've made but can't get to a hardware store to buy the 6" flange required (we are on lockdown and curbside pickup is like 1-2 off). I'll try using that I just dunno how to uh cut and fasten it to the ducting.

I don’t pull outside air but if I did, this is the route I would take.

I use a window AC. If it's not hot, I just leave the fan on. Rest of the room is sealed

AC Filter. That said, I've run filterless before with no issues.

If I vent I pull thru a merv13 to block dust dirt mites mold and crap. I found restriction can quickly become a problem when they get dirty.
