Why Indoor Air Quality Matters
Americans spend 90% of time indoors where pollutant concentrations can be 2-5x higher than outdoors. Poor air quality affects sleep, allergies, and long-term health.
Common Indoor Air Pollutants
Particulates (dust, pollen, pet dander), VOCs (paints, cleaners, new furniture), CO (combustion appliances), radon (ground seepage), mold spores, and bacteria.
DIY Testing Options
Home test kits measure radon, mold, and some VOCs. Portable air quality monitors track particulates and CO2 levels in real time.
Professional Air Quality Assessments
Certified assessors use calibrated instruments to measure particles, gases, humidity, and airflow. They identify sources and recommend targeted solutions.
Interpreting Results
PM2.5 under 12 µg/m³ is good. CO2 under 1000 ppm indicates adequate ventilation. Relative humidity between 30-50% prevents mold and dust mites.
Improvement Strategies
Solutions include better filtration, source control (removing pollutants), increased ventilation, air purifiers, and humidity control.
