It's been brought up in the above posts, but yes, there are fan filters you can buy. Look for them in the fan guard/cover section of the store. It attaches directly to the fan housing through the screw holes. Even better if you can get those silicone screw stumps that you can stick in to help reduce vibration.
The filters aren't much more than a mesh or cotton/steel wool type setup. It will grab the dust as it passes through.
