What can excessive air pressure in a home lead to regarding indoor air quality?

Excessive air pressure in a home can lead to increased moisture levels, impacting indoor air quality significantly. When pressure builds up, it can force outdoor air, which may carry higher humidity, into the home. This moisture can accumulate in various areas, potentially leading to condensation on surfaces, mold growth, and other moisture-related problems.

High moisture levels can exacerbate health issues, particularly for individuals with respiratory problems or allergies, and can also affect the integrity of the building structure over time. This excessive moisture can create an environment that is not conducive to healthy indoor air quality.

While stagnant air and decreased energy efficiency are related considerations, they are outcomes that do not specifically correlate to the direct consequences of excessive air pressure in the same way that increased moisture does. Improved air quality would also not be a result, as high moisture typically leads to an environment that can foster pollutants and allergens.
