It is commonly believed that most pollution is found in industrial areas, near landfills and factories. While we can certainly avoid such places, most of our time is spent indoors, not in natural park areas. This accounts for approximately 90% of our entire lives. For the majority of people, work, education, meals, and sleep all take place within enclosed spaces. These are areas where the air is not refreshed but rather circulates. This is especially relevant now, as many people are not even going outdoors to commute to work due to remote working and studying from home.
