I have something like an air cannon and a bottle of parts cleaner that drys fast. Dunno if this combination will work but I will try to clean it tomorrow.Well you can clean some with an air cannon and special dry cleaning solvent
We get this done with the skid steer because its filters are over $ 100 and they need cleaning almost daily in very dusty conditions
Down side is it cost $ 40 a hit
These air filters are throw aways .
