You can always mix it up by using only Scotch Brite or only cheesecloth, but using both will ensure that dust particles big or small will stay out of your system.

Let me know if you decide to try this because I have been wanting to try this idea out, but never got around to it!
Surgical Gauze... I used Surgical Gauze, two layers of it over the fans intake grills.. Works like a charm.. Figured this out before the mentioning of cheesecloth I'm sure it'll work just the same
