What Causes Poor Indoor Air Quality?

Breathing in clean air is essential for our health. Unfortunately, the air inside our homes can be more polluted than outdoor air. Poor indoor air quality can be caused by a variety of factors, including dust mites, mold, pet dander, and chemicals. In this blog post, Atomatic Mechanical Services discusses some of the common causes of indoor air quality problems as well as solutions to improve indoor air quality in your home.

Common Causes of Poor Indoor Air Quality

Dust Mites

Dust mites are microscopic bugs that live in the dust in your home and feed off dead skin cells. They are one of the most common causes of poor indoor air quality and can trigger allergies and asthma attacks.


Mold spores are everywhere—in soil, on plants, in food—but they can also form indoors when moisture accumulates from condensation or leaks from plumbing or appliances. They can release spores into the air, which can cause allergic reactions and respiratory problems in people who are sensitive to them. Mold growth can cause symptoms such as itchy eyes and throat irritation, and make your house smell musty.

Pet Dander

Pet dander is tiny particles of skin shed by cats and dogs that become airborne when disturbed by vacuuming or simply walking around your home. These particles contain proteins that can trigger allergic reactions in people sensitive to them.

Poor Ventilation

One of the most common causes of polluted air indoors is poor ventilation. Ventilation is the process of exchanging air between indoor space and the outdoors. If a space is not properly ventilated, pollutants can build up to dangerous levels. Opening windows once in a while can help with ventilation, or investing in a mechanical ventilation system can also combat poor air quality.

Cigarette Smoke

Cigarette smoke is one of the most common indoor air pollutants. Cigarette smoke contains over 4,000 chemicals, including more than 70 that are known to cause cancer. Exposure to cigarette smoke can lead to a variety of health problems, including respiratory infections, asthma, and cancer.

Volatile Organic Compounds

Volatile organic compounds (VOCs) are chemicals that are released into the air from a variety of sources, including cleaning products, paint, building materials, and office equipment. VOCs can cause a variety of health problems, including headaches, dizziness, and nausea. Additionally, long-term exposure to certain VOCs has been linked to cancer.


Radon is a radioactive gas that is produced by the breakdown of uranium in soil and rock. It can enter homes through cracks in the foundation or other openings and build up to dangerous levels. Radon exposure has been linked to lung cancer, so it is important to have your home tested for radon if you live in an area where it is present in the environment.

Tools to Improve Air Quality in Your Home

Cleaner indoor air isn’t difficult to achieve. With comprehensive HVAC system solutions—like whole-home dehumidifiers and air cleaners—you can take charge of your comfort levels while creating a safer and healthier living space. This doesn’t mean you’ll have to start wearing a mask daily, either. These tools connect to your current HVAC system, so they help improve the air quality within your entire home, not just in certain rooms. They are also easy to maintain and they might even add value to your home when it comes time to sell.

Whole home dehumidifiers help homeowners remove moisture from the indoor air supply and avoid problems with mold growth. Air cleaners remove particle pollutants such as dust mites, pet dander, and more to minimize allergy and asthma symptoms. These measures provide effortless solutions that keep both airborne irritants and moisture under control, so you can count on breathing easily both day and night.
