Indoor air quality (IAQ) has become one of the most important topics in the HVAC industry. In the past, the focus of HVAC design was simple comfort—primarily maintaining temperature. Today, we understand that temperature is only one piece of the comfort and safety equation.
According to research published by PubMed.gov, most illnesses linked to environmental exposure originate indoors. When you consider the cumulative time people spend at home, at work, and in other enclosed spaces, IAQ becomes a critical component of long-term health.
What Affects Indoor Air Quality?
Poor IAQ is more than just “stale air.” Buildings can accumulate a wide range of contaminants, including:
- Cleaning solvents
- Paints and chemicals
- Pesticides
- Carbon dioxide (CO₂)
- Volatile organic compounds (VOCs)
- Radon gas
- Off-gassing from furniture, carpet, and building materials
- Fumes from attached garages
These contaminants can contribute to:
- Eye, nose, or throat irritation
- Headaches
- Drowsiness or fatigue
- Allergic reactions
- Asthma triggers
- Reduced cognitive function
- Over the long term, even serious health risks
Simple Solutions You Can Start With
Basic maintenance and proactive habits can dramatically improve IAQ.
Replace air filters regularly
Dirty filters restrict airflow and recirculate contaminants.
Use air purifiers or room air cleaners
Especially helpful for allergy or asthma sufferers.
Consider UV germicidal lamps
UV-C technology helps neutralize airborne pathogens.
