Why Indoor Air Quality Matters More than Most Homeowners Realize

February 24, 2026

Indoor air quality significantly impacts health since Americans spend approximately 90% of their time indoors, where pollutants can be more concentrated than outdoor air. Common indoor contaminants include mold, dust mites, volatile organic compounds from household products, tobacco smoke, and outdoor pollutants that seep through building gaps, all of which can cause respiratory problems, allergies, and other health issues. Utah faces unique challenges with wildfire smoke and winter inversions trapping particulate matter, while the state has recently experienced increased flu cases that may actually be symptoms of poor air quality.

What action is being taken

Why it matters

Indoor air quality is critical because Americans spend the vast majority of their time indoors where pollutant concentrations are often several times higher than outdoor levels. Poor indoor air quality can cause serious health consequences ranging from allergies and respiratory issues to more severe problems like liver damage, nervous system damage, and cognitive impairment affecting decision-making and sleep. Utah faces additional challenges with environmental factors like wildfires and winter inversions that compound indoor air quality problems, making it especially important for residents to take preventive measures to protect their health in spaces where they spend most of their time.
