Has anyone tried Pantyhose as a fan dust filter?

Never tried the pantyhose as a dust filter before. Hate to mess up a good pair of my pantyhose for that.:) Anyway, you could also use something like this. http://www.walmart.com/ip/Duck-Foam-Air-Conditioner-Filter/17133827 I am using this as an extra front dust filter on my Phanteks Enthoo Pro case. Seems to help out a great deal and I have not noticed any higher temps in my system, but your mileage may vary. Simply cut it to size and figure a way to attach it to the case. I use tape to secure mine in place. It's behind the front panel and not seen.
