About 6 months ago, I switched to NoToil. This system requires not gas or solvent to clean the filter, just a bucket of warm water and a little crystal cleaning solution. Since I have 4 filters for each bike (I, too, hate cleaning filters), I don't have to clean very often, but when I do, I don't have to put up with the odor that goes along with solvents. In fact, NoToil is so easy on the nose, I put all the filters on the dash for drying, and then slip them into individual freezer zip bags for storage.
