Air quality indoors is often worse than it is outdoors. Although mold is the most common indoor air quality problem, carbon monoxide and chemicals from products used indoors and off-gassing building products are also sources of problems.
Inadequate ventilation with fresh outside air compounds indoor air problems. It leads to moisture accumulation, mold growth and elevated concentrations of airborne contaminants that cause or worsen asthma symptoms.
We’ve compiled information and tips into this online resource to help you keep your indoor air clean and healthy.
