AIR QUALITY

Prior to the start of the school year all HVAC systems will be serviced and new filters installed. These filters will have the highest MERV rating that the manufacturer recommends. MERV, or the Minimum Efficiency Reporting Value, measures and evaluates system efficiency. An independent evaluation of the ventilation systems commenced on July 20th and will provide a report as required by the Connecticut Department of Health (CT DPH). All classroom unit ventilators have been serviced with new filters installed with plans and capacity to run continuously. Additionally, restroom exhaust fans will run continuously, when school is in or out of session. Staff are advised not to run floor or wall mounted fans to avoid horizontal air flow in alignment with guidance from the CDC and the CT DPH. Window air conditioners, however, will operate in fresh air mode to create a comfortable environment for students and staff. As a part of daily operations, all school days will begin with a two hour purge cycle of all mechanical ventilation systems. A second one hour purge cycle will follow at the end of each day.
