How to use CDC building recommendations in your setting
Opening windows, using portable air cleaners, and improving building-wide filtration are ways to increase ventilation in your school.
While implementing ventilation strategies, be sure to continue to take regular precautions to keep young children safe, such as using fans with covers and windows with screens.
Good ventilation is important, especially in areas where children may not be able to wear masks. If students eat in a common area, use methods such as opening windows, maximizing filtration as much as the system will allow and using portable HEPA air cleaners.
Proudly protecting kids, students, staff and teachers in over half the states in the US.
