Many people either assume that dirt and dust are about the only pollutants in their vents and their home, or they couldn’t care any less. However, they’d be both mistaken and surprised at the sheer number of things that can and often do lurk in their air duct systems.

Now that winter is upon us, and many of us are having our HVAC systems cleaned, we decided to put together this piece so that people know what to look out for. Here are some of the common pollutants lurking in your vents. Take a look.

Pollutants That May Be Lurking in Your Vents

The best-case scenario is that you simply have dust and dirt polluting your vents and your house. However, that may not be the case. Here are some of the most common pollutants found in air duct systems:

  • Dust mites
  • Dirt
  • Germs
  • Pollen
  • Mold
  • Bacteria
  • Fungus
  • Human and/or pet hair
  • Food

Some of the less common pollutants include:

  • Air pollutants
  • Human and/or animal dander
  • Trash
  • Toys
  • Tools
  • Construction material
  • Rags
  • Clothing
  • Jewelry

  • Insects
  • Animal poison pellets
  • Dead/rotting animals
  • Rat/mouse nests
  • Animal feces
  • Bird nests

How Often You Should Have Your Vents Cleaned

Far too many homeowners believe that having a filter is enough to not have their vents cleaned. They’d be mistaken because it doesn’t matter how good your filters are; your vents will undoubtedly collect pollutants because many of them can through it.

Generally speaking, you should have your vents cleaned anywhere between two to five years. If you maintain your system properly and exchange the filters about twice a year, you can delay your next professional cleaning without impacting your system negatively. If the system’s never been cleaned for over three years, you need to have it cleaned immediately.
