The latest research reports confirm that air pollution is harmful to health and can even lead to death. According to statistics, hundreds of millions of people in North America live in areas with abnormal and unhealthy levels of air pollution, with dust and smog being the most common forms. The reports indicate that vehicle exhaust, toxic fumes from factories and power plants, and ash from indoor and outdoor wood burning are the primary causes of particulate matter and ozone pollution.

The higher the ozone levels, the greater the risk of premature death. Ozone is an extremely reactive oxidizing gas that can irritate the respiratory system and even lead to death among patients with asthma and other respiratory conditions. Research has shown that ozone can cause breathing difficulties and asthma attacks; children, the elderly, and asthma sufferers are at the highest risk.

It has been proven that airborne particulate matter and dust can shorten the lifespan of those who are exposed to them over the long term. Particulate pollution can trigger heart disease, blood clots, lung cancer, and asthma attacks. People should recognize the importance of environmental protection; early prevention and the purification of polluted air are essential, and installing a suitable air purifier indoors is also worth considering.
