How Do Indoor Air Contaminants Hurt You?

As a whole, we give a lot more attention to outdoor air quality than indoor. You watch the morning news and are told whether your city is on green, yellow, or red and what precautions to take if you need to venture outside. But what about indoor air pollution?

According to the World Health Organization, approximately 4.3 million people die annually due to indoor air pollution. That is over half a million more people than those who die as a result of outdoor contaminants. Luckily, with the right HVAC service in Atlanta, you can reduce contamination and improve your health.

The Unexpected Dangers Inside Your Home

It seems counterintuitive for most, but your indoor air is likely two to five times more polluted than the air outside—especially during the very hot and cold months when you keep your windows closed. Outdoor pollutants become trapped inside, new pollutants originate within the home, and your HVAC system circulates them through your ducts, spreading them to every room.

Part of fighting back is understanding common sources of indoor air pollution. Here are the main ones to look out for and how HVAC contractors in Atlanta can help you.


Easily the most common indoor air contaminant type, dust is made up of dead skin cells, fibers, and dirt. It also serves as an excellent home to dust mites and various allergens. The best way to fight back against dust, besides regular and thorough cleaning, is to have your HVAC filters properly maintained.

Combustion Products

You might not think you have these in your home, but you likely have several. Dryers, water heaters, and furnaces are all common combustion products. These introduce CO2 into the home if there is improper ventilation. Your HVAC contractor can assist with ensuring the appropriate venting is in place.

Excess Moisture

You need a certain amount of humidity in your home for your health and comfort, but there can be too much of a good thing. Excess moisture allows mold and mildew to grow, both of which can cause respiratory diseases. HVAC contractors can install humidity regulation on your system.

Health Effects of Indoor Air Pollution

Symptoms of indoor air pollution can range from the minor to the severe. Signs that indicate you might have an indoor air pollution problem include:

  • Coughing
  • Sneezing
  • Itchy and watery eyes
  • Fatigue
  • Headaches and migraines
  • Congestion
  • Dizziness

These symptoms and the pollution that causes them can tie into a wide variety of health problems, from rhinitis to tachycardia.
