Indoor Air Quality

 Indoor air quality is a term which refers to the air quality within buildings and structures. Indoor air quality can be affected by gases such as carbon monoxide, radon, and volatile organic compounds. Indoor air quality can also be affected by particulates and microbial contaminants such as mold and bacteria. All of these factors can affect the health and comfort of building occupants. Poor indoor air quality can bother the eyes, nose, and throat, and may even lead to chronic heart and lung problems and cancer. Air pollution in the home can come from wood smoke, tobacco smoke, gas-burning furnaces and appliances, radon gas, mold, and other allergens.  By controlling and eliminating the source of any contamination along with proper air filtration and ventilation, indoor air quality can be improved.
