Why Does My House Feel Stuffy? Air Quality Testing in Seattle, WA
If your house feels stuffy, stale, or uncomfortable, your indoor air quality may be the cause.
Many Seattle homeowners experience this issue, especially in homes with limited ventilation or hidden air quality problems.
At 5 Microns Inc., we provide indoor air quality testing to help identify what’s causing poor airflow or uncomfortable indoor conditions.
What Causes Stuffy Air in a Home?
Stuffy air is usually caused by a combination of factors:
- poor ventilation
- high humidity
- buildup of airborne contaminants
- off-gassing from materials (VOCs)

Modern homes that are tightly sealed can trap contaminants inside.
