Exposure to poor indoor air doesn’t affect everyone the same way. People with autoimmune disorders, asthma, or allergies tend to be more sensitive. So do young children, elderly adults, and individuals recovering from chronic illness or mold exposure.

Common symptoms linked to poor IAQ include:

• Fatigue and brain fog
• Headaches or sinus pressure
• Wheezing, coughing, or chest tightness
• Skin or eye irritation
• Increased frequency of respiratory infections

Over time, chronic exposure can worsen underlying conditions and affect the body’s ability to heal. That’s why improving IAQ is not just about comfort—it’s about supporting long-term health and recovery.
