as we send our children to school everyday, it's important to know how clean and healthy their schools are. because students spend approximately 14,000 hours inside buildings over the course of their school years, one area of growing concern is air quality in schools - particularly for children suffering from allergies or asthma.
asthma affects close to five million children and leads to 10 million missed school days every year, according to the american lung association. That makes asthma the number one cause of school absenteeism due to chronic illness.
