Use compressed air keyboard cleaner to clean air vents
Air vents can harbor a lot of dust and dirt and it is important that you also clean them. But since most parts of the air vents are inaccessible, there is still a way to dislodge the dirt by using compressed air from a keyboard cleaner. Compressed air sends air at a high pressure and speed through a thin straw thus it allows you to direct the airflow to the part of the air vent that needs cleaning. To catch the dust, you can also work with a hand vacuum to collect the dust that has been removed from blasting compressed air.
