There was a leak at a methane storage facility in the LA area. Several schools were provided air filters well after the event (methane is lighter than air). They had the filters for four months even though the methane levels were normal. Test scores increased.
So if methane levels were normal what were the filters taking out of the air? I don’t really know what air filters filter out can they remove CO2 because that’s been proven to lower IQ levels

Perhaps dust and particulates? The SoCal area is very dusty. If you leave your car parked for a few days it will have a fine layer of dust on it.
Imagine breathing that in along with all the other germs normally present in a classroom. Less sickness should allow more learning.
