[Drain You]

Dust in my case is really building up, is there anything I can use a filters so dust doesnt get in so easily?

fine window screen might work, but remember something too filtering might restrict air flow

you can always use paper towels. but it might restrict airflow so i wouldn't use the heavy bounty types but maybe the store brand.

edit:
duh forgot about this stuff.

they have this foam filter stuff that is thinner than that in the picture. they usually use it as a cushion padding in like steel breifcases. i acutally cut some and put it on my carburetor on my car.

I have one of those and it works pretty well.

If you wanted to make something you could always use pantyhose. It won't restrict the airflow.
