Indoor air quality can also become a concern in places where outdoor air quality is relatively better and less risky, and where questionable pollutants are present inside the home. To put it simply, even a simple drop in air quality could be recorded by a simple chore like cooking, and the presence of multiple emission sources in an indoor space can lead to poor air quality levels. , cumulatively.
