I know that our teacher's union and the district we work for negotiated for almost a week about air filtration and circulation. The HVAC is continuously circulating air from the time it is on until after school when it turns off. There is some time before school and maybe 20min after school when it is on. They have settled on only pulling air from the outside instead of recycling the warm or cool air in the room. And having some kind of agreement on the merv rating of the filters. It may be merv 7(but I'm not sure.) |
