Measuring levels of indoor pollutants is the most effective method for assessing air quality in buildings. This approach involves using specialized instruments to quantify the presence of various harmful substances in the air, such as volatile organic compounds (VOCs), carbon dioxide (CO2), particulate matter, and other pollutants. Such measurements provide concrete data about the quality of indoor air and help identify specific contaminants that may pose health risks to occupants.

In contrast, while visual inspections and smell tests can provide some insights into potential issues, they lack the precision and reliability of direct measurements. Visual inspections might identify visible mold or dust, but they do not quantify the pollutants present or assess the air quality comprehensively. Similarly, relying on odor can be misleading, as some pollutants may not produce a noticeable smell. Temperature readings, although important in creating a comfortable indoor environment, do not directly indicate air quality or the presence of harmful substances.
