PC case dust filter input needed

[Cantih]

So, the apartment where I'm at builds up dust at a rate faster than I've seen anywhere else I've lived. It's severe enough that I want to put some protection between it and my computer.

I can't afford dropping cash for stuff specifically made to mount to a case, so what I'll do is go to the hardware store and get filter material and just MacGuyver it in place.

But, I don't know anything about filter material other than more filtration = less airflow. Does anyone know their stuff about this? What exactly should I go to the store and ask for that will do the job without fucking up my PC?

Higher MERV# = better. Could buy a [good/merv8+] pleated filter and dismantle it.

Do you have central air? If so; it probably has a cheapo fiberglass filer in it, which is literally doing nothing and would be linked to the greater problem.

No central air. Not even a window mounted A/C. And windows closed too, more often than not.

I've been using these:

No tools necessary, just slap it on. I used to just tape some dryer sheets over my intake fans lol.
