[Pc_Support] Filter material?

[Justin M. Keyes]

Hi,

A few people have mentioned that they put filters on their PC. I'd
like to know what material you use. Please don't say "cut from an A/C
filter"--I tried cutting a new A/C filter and it is too flimsy and
falls apart and creates its own particles.

Part of this[1] thread suggests that filters aren't even a good ROI...
