The air quality in the basement could be poor for numerous reasons. Basements are more likely to have air quality problems than other areas of the house; they fight not only humidity problems but also water issues such as leaks and floods. These problems aren’t good for overall air quality because they directly correlate to allergens and other negative factors such as mold. All these elements directly cause poor air quality throughout the home.
The air from the basement also moves upward, whether it’s through the ventilation system or simply through the normal movement of air throughout the house. This is exactly why the air quality of the basement negatively affects the air quality of your entire home.
