Poor indoor air quality can be somewhat deceptive. People suffering from coughing, chest tightness, sore throat, shortness of breath, or watery/itchy eyes might blame it on COVID-19, or allergies, or the common cold, but these same symptoms can be caused by simply having bad indoor air.
If you suspect you have poor indoor air quality, there are plenty of things you can do to improve the situation. The first thing you’ll want to do is try to identify the cause of the problem so that you can correct it. For example, is your air conditioner’s filter clogged, or is there standing water or mold inside of it? Is there a smoker in the house that does most of their smoking indoors? Are strong chemicals regularly used inside the house? Do your pets produce a lot of dander? Are your stove and other heating elements properly ventilated? These are just a few common contributors to poor indoor air.
