|Why air quality matters-- some important facts to consider|
The quality of air in your home, office, or school can have a big impact on your overall health. Poor air quality and air pollution contribute to lung disease, including respiratory tract infections, asthma, and lung cancer. Lung disease claims close to 335,000 lives in America every year and is the third leading cause of death in the United States.
Poor indoor air quality can cause or contribute to the development of chronic respiratory diseases such as asthma and hypersensitivity pneumonitis. In addition, it can cause headaches, dry eyes, nasal congestion, nausea and fatigue. People who already have respiratory diseases are at greater risk.
Biological pollutants, including molds, bacteria, viruses, pollen, dust mites, and animal dander promote poor indoor air quality and may be a major cause of days lost from work and school. In office buildings, heating, cooling, and ventilation systems are frequent sources of biological substances that are inhaled, leading to breathing problems.
So, it is very clear that poor air quality can lead to some very serious health problems. There are a number of steps people can take to improve the air quality in their homes and offices. These include proper ventilation, limiting the source of pollutants, and using effective air purifiers and cleaners
