What Causes Poor Indoor Air Quality?

Many things can contaminate your indoor air and leave it dirty and unhealthy. According to the Centers for Disease Control and Prevention (CDC), the three most common categories of pollutants that cause allergic reactions are germs, particulates, and VOCs (volatile organic compounds). Each of these pollutants is responsible for approximately one-third of indoor allergic reactions.



More specifically, indoor air is often polluted by:
- Dust
- Mold
- Pet dander
- Dirt
- Bacteria
- Mildew
- Viruses
- Chemicals
- Cooking fumes
- Paints
- Cleaners
- Aerosol sprays
- Pesticides
- Wood preservatives
- Building materials and furnishings
This list is not exhaustive. There are many things that can lead to poor IAQ, but the list above are the most common culprits.
How Do You Know If You Have Poor Indoor Air Quality?
Poor indoor air quality can affect not only your entire home but also your health. In order to avoid suffering serious consequences, it is best to become aware of the various indicators of poor IAQ.

Your Health
Symptoms of poor IAQ are very similar to those of asthma, allergies, and the common cold or flu. Therefore, it can sometimes be difficult to determine the exact cause of your symptoms. Most often, victims of poor IAQ report that their symptoms alleviate upon leaving their home for an extended period of time.
These symptoms include:
- Coughing
- Sneezing
- Watery, itchy, or dry eyes
- Shortness of breath
- Dizziness
- Fatigue
- Fever
- Nausea
- Sinus congestion
Your Home
Much like your health, your home shows signs that it is affected by poor IAQ. If you notice low airflow, foul odors, mold, significant dust buildup throughout, excessive humidity, or mildew in your home, chances are that you have poor IAQ.
To know for sure if your family and your home are suffering from poor indoor air quality, you need a team of experts on your side who can perform an accurate indoor air quality assessment. If you suspect that the air in your home is unhealthy, reach out to our Long Island indoor air quality team right away.

Indoor Air Quality FAQs
How do I know if my Long Island home has poor indoor air quality?
Signs include dust buildup, lingering odors, allergy flare-ups, or respiratory discomfort. Professional IAQ assessments measure pollutants, humidity, and ventilation effectiveness. Early detection prevents health problems and improves comfort.
What indoor air quality systems are best for allergy sufferers?
Air purifiers, advanced filtration, and humidity control can reduce allergens and irritants. IAQ systems also remove dust and pet dander before circulation. Regular maintenance ensures consistent, healthy air.
How often should duct cleaning be performed in Long Island homes?
Every 3-5 years is typical, but more frequent cleaning may be needed for homes with pets or high dust levels. Clean ducts improve airflow and system efficiency. Timely cleaning supports better indoor air quality.
Do UV lights really improve indoor air quality?
Yes, UV lights neutralize bacteria, mold, and viruses within your HVAC system. This prevents microorganisms from circulating through your home. Combined with filtration, UV lights significantly improve indoor air health.
