Indoor air quality tests turn invisible household conditions into useful measurements. A typical assessment may track fine particles, humidity, temperature, carbon dioxide, and certain gases or chemicals. The results can help you connect everyday symptoms, such as dusty surfaces or a persistent musty smell, with possible sources inside your home. Since air quality testing can cover several measurements, each result needs context. One elevated reading rarely tells the whole story, but patterns across rooms and times of day can reveal where to look next.
