• School Building Cleaning, Disinfection, Sanitization, and Air Quality Precautions for COVID-19

    All Southern Lehigh School District support service staff will clean, disinfect, and/or sanitize each classroom, restroom, hallway, and touch points per existing CDC Recommendations on Cleaning Public Facilities.


    All Southern Lehigh school buildings have been designed to meet ASHRAE standards for continuous air filtration and the introduction of filtered outside air.

    • School building ventilation and filtration should continuously operate during occupied times.
    • MERV 13 filters will be used during the pandemic. Filtration of no less than MERV8 will be used if MERV 13 filters are not compatible.
    • Outdoor air circulation should exchange indoor air multiple times per day. At no time should it fall below ASHRAE levels for occupied buildings.
