Q: Can dirty return air vents make you sick?

• <div><p>You can experience respiratory problems if your return air vents are dirty. While this doesn&rsquo;t necessarily mean dirty return air vents will make you sick, they can exacerbate symptoms of respiratory illness, such as sneezing, wheezing, and coughing.
