Here's what I use for a filter, it's an air filter off a small car. It lasts for months of constant use.
Now you don't have to go this far, but if you really need to keep the computer clean, you'll have to use a hi-quality paper filter designed for the purpose. Anything less.....you're just kidding yourself about filtering.
