IAQ Pros Team August 18, 2026 ~4 min read
The hidden problem with indoor air
Most people assume indoor air is cleaner than outdoor air. Studies show the opposite — indoor air can be 2 to 5 times more polluted, according to the EPA.
Common indoor pollutants
- Pollen and dust tracked in and circulated by your HVAC system
- Pet dander that lingers in ducts and filters
- Volatile organic compounds (VOCs) from paints, cleaners, and furniture
- Mold spores that thrive in humid basements and ducts
Practical steps to improve air quality
- Upgrade your filters to MERV 11 or higher.
- Add a whole-home air purifier to capture fine particles.
- Control humidity between 30–50% with a dehumidifier.
- Schedule duct cleaning every 3–5 years.
