As a 40+ year professional auto technician, I can unequivocally state “DO NOT USE COMPRESSED AIR TO CLEAN ANY FILTER”
Sorry to shout, but when you use compressed air, you are destroying the filter’s ability to filter. Compressed air will take the dirt particles and blow them through the filter media, creating holes in the filter. Even blowing backwards causes this. Best thing to do is tap the filter to dislodge the dirt.
