School BusesFor all of the children that take the bus to and from school, a safe journey is expected. Not just with an overcautious driver, but with the air quality. Children are more susceptible to air pollution because they breathe more rapidly than adults and their immune system and their cardiovascular systems are not at their prime. There are many health effects that children suffer from due to vehicle-emitted particulates. Due to the lack of strength that their immune systems have, it is important that we keep the air in school buses clean.
Mass Transit Public BusesChildren aren't the only ones susceptible to air pollution. The elderly and those with breathing problems are also at risk for negative health effects due to contaminated air with the lack of a proper filter.
Proper FiltersDepending on the size of the bus, air filter sizes may differ. Although the sizes of the filters will vary, the range of efficiency will not. On the MERV rating scale, 9 to 12 would be the typical bus filter. Ratings 9 through12 can trap auto emissions and keep the buses engine sturdy and reliable. Air filters used on highway vehicles should not be cleaned because it will most likely injure the air filter media. If the filters are not properly functioning, the filter should be changed.
