5 Tips for Disinfecting a Classroom

Filter the Air

Air filters are another item that aren't likely to be in the school supply budget, but having one in your classroom can help remove close to 100 percent of environmental allergens, like pollen and dust, and also bacteria, from the air. A good quality high-efficiency, particulate-arresting (HEPA) filter can be purchased for under $100 and can make a huge difference in the quality of the air in a classroom. Germs breed in warm and stagnant air, so teachers should also open doors and windows whenever possible to keep fresh air flowing.
