Filtering doesn't have to be expensive if you're in no big hurry about it. A 2 micron sock filter is cheap and will filter tens of gallons of oil before needing to be washed out (inside out with clean fuel or RUG) and they can be washed and reused a dozen times or more.

Make it easy on yourself: use two layers of filter: a used jean leg double-stitched closed on the end inside a 1-micron sock filter.
The jean leg will last about 25 gallons (filters to about 5 microns) and the sock filter will last about 100 gallons before you have to rinse it. After you rinse it you're good for about another 75 gallons with the sock filter.
