Clean air vents in your home by following a few simple steps found in this guide. In most homes, air vents are on the ceilings while some homes, such as a mobile home or homes on a wooden platform, will have the air vents on the floor. Air vents are important to keep clean since it comes in contact with the air you breathe while in the house. Breathing in dust is not healthy and can get you sick.
Unscrew the cover to the air vent. Get a wet rag and wipe inside the vent area. You can also vaccuum inside the vent area, but don't go up too high in order to prevent losing any part of your vaccuum cleaner.
Keep the air vents free from clutter. Don't pile boxes by an air vent, since the boxes can block the air coming through and make the other air vents work twice as hard. If the vents are on the floor, do not cover any of them or it will make dust accumulate on the other air vents quicker.
