How Dust in Ducts Formed?

Air is stirred by passing air compressors or blowers, and small particles of dust are suspended in the air as it passes through ducts. Some people might wonder why there is dust in ducts – after all, there are no holes or spaces in the ductwork that cause this to happen. The answer to this is complicated, but simple to answer – dust is always in motion.

Dust in Ducts

The reason for dust in ducts is most often because of the movement of dust from one place to another. Take a shower, for example, and you will see that the water and the shampoo and other cleaning products and residue will go down the drain or “down the hatch”. However, as it comes back out into the air, more of it will be stirred back into the air. That’s because when you take a shower, the water and shampoo and other particles are already in the air, so when you dry off your hair with a hair dryer, those particles are stirred back into the air. Over time, they will become a dust cloud – and that dust can become quite mottled and fuzzy.

Dust in ducts is not only found in showers and toilets, either. Duct work in the home is used a lot, too. Closets and pantries may be dusty, as may basements and attics. If you look outside and see dust in your yard, that may also be coming from the ducts in your house – but you need to be able to identify it to figure out how dust in ducts is formed.

How Dust Moves in Ducts?

To figure out how dust in ducts is formed, you need to know how dust moves. It starts off the same way in every room in your house – hot air rises, cool air descends. But once that air goes up and out, some of it is heated and sticks to the ceiling or the closet ceiling fan. The heating air rises, carrying dust particles with it.

The next time you take a shower, you may notice dust on your face – that’s dust from the dryer. And after you go to bed, the dust returns to the dryer. The air conditioner kicks on and the dust from the dryer and the air conditioner mixes – the dust in ducts is stirred around and becomes airborne. The dust in ducts can go up into your lungs and cause health problems, especially lung cancer, if not taken care of.

  • By sending air down a long tube, where it becomes heated and turned into dust, which settles on other parts of the long tube. If the dust is carried into a room, it is breathed in by you, and settles on the carpet, your clothes, your furniture and everything else in the room. The dust then begins to become airborne, and you breathe it in.
  • Dust becomes airborne when someone coughs or sneezes, which sends tiny particles of dust into the air. When an air conditioner goes on, all those tiny particles of dust are collected into tiny droplets of air, which are then carried into the air conditioner and become airborne. When you have a cold, allergies may set in. The tiny particles of dust from the anemone can become airborne when you breathe them in, when you brush your teeth, eat food, mow the lawn or blow your nose. When these small particles of dust become airborne they land on something and become airborne.

The Bottom Line
