7 Most Common Contaminants Found in Air Ducts

Even after hours of cleaning your house, you can never be sure that it would be 100% clean. In fact, there is a high chance that millions of microscopic airborne contaminants are found in places you least expect, such as air ducts. This is also why air duct cleaning Ashburn VA is very popular nowadays.

Oftentimes, homeowners wouldn’t bother as long as hot or cold air comes out and there’s no chemical smell. Unfortunately, that is not the case. Read on as we list down seven of the most common contaminants found in air ducts.

Everyday dust and dirt

Contaminants can be categorized into animate and inanimate particles. The most common inanimate particle would be everyday dust and dirt. This can form a layer inside your air ducts. When you turn on your HVAC, the particles are sent back into your home.

Dead skin cells

Dead skin cells from humans is another example of inanimate particles. Did you know that we lose about 40,000 dead skin cells every minute of the day? That’s about 57,600,000 dead skin cells every day. This is why regular air duct cleaning Ashburn VA is crucial to ensure the health of everyone living inside the house.

Pet dander and dust

This would include dust and microscopic flecks of skin that are shed off by your furry friends. We’re not just talking about the common house pets like cats and dogs. Even rodents and birds or basically any creature that has fur or feathers can leave bits of their skin around the house. These can cause allergic reactions when inhaled.


Fiberglass is one of the most common types of fiber-reinforced plastic that uses glass fiber. Inhaling fiberglass can be very dangerous. It can cause soreness in the throat and nose, which could potentially be the cause of asthma and bronchitis. A great way to prevent this would be to schedule a regular air duct cleaning Ashburn VA services.


Asbestos, on the other hand, is a natural mineral and carcinogen. Oftentimes, this would come with warnings because of its ability to cause long-term breathing issues when inhaled. With incomplete construction projects around the house and a very dirty HVAC system, it could travel inside your ducting and down the line.

Mold spores

Mold spores are examples of an animate contaminant that can be found in every home. What you need to look out for are cases of molds colonizing on dangerous levels. This typically happens when there is condensation in your air ducts. Be sure to clean them regularly so it wouldn’t contaminate the air inside your house.

Dust mites

Lastly, dust mites, which is another example of an animate contaminant, are very abundant in homes. The good news is that these are not as dangerous as their inanimate counterparts. You only have to ensure that they don’t grow exponentially in one location.

Always be sure to watch out for any of these contaminants in your HVAC systems as your air ducts are the contaminants’ favorite place to hide and, once you turn it on, these will be dispersed and inhaled by the people you love! Be sure to hire a professional to clean your air ducts to maintain the air quality that you breathe.
