What is a common method for testing air quality in homes?

Air sampling and analysis is a widely accepted method for assessing indoor air quality because it provides concrete data on the presence and concentration of various pollutants and allergens in the air. This method involves collecting air samples through various means, such as passive or active sampling, and then analyzing these samples in a laboratory for specific contaminants, including volatile organic compounds (VOCs), mold spores, particulate matter, and other harmful substances.

By utilizing air sampling and analysis, home inspectors and environmental professionals can obtain objective measurements that help evaluate the safety and comfort of indoor environments. This methodology can often reveal problems that might not be detected through visual inspections or subjective assessments, making it a critical tool for ensuring a healthy living space.
