Better Classroom Ventilation Better Attendance means more learning and more dollars Better Student Health California Study of 168 Classrooms1 Increasing classroom VRs from the California average (8.5 cfm per person) to the State standard of 15 cfm would decrease Illness Absences by 3.4% Texas Study of 120 Classrooms2 Median CO2 levels were 28% higher than ASHRAE limit Washington & Idaho Study of 434 Classrooms3 A 1000 PPM increase in CO2 was associated with a 10% - 20% increase in student absence School funding often depends on daily attendance, so better attendance may often pay for ventilation upgrades.
