You are 100% correct- this is the only sensible approach to sending children (and their teachers) into a germ-warfare situation every new term time. This is not the 50’s - we are traveling all over the world and exposing ourselves and each other to 100’s more viral and bacterial infections than ever before.
All of the people voting this down are not just unreasonable, they are delusional! They are the same people sipping cocktails on the titanic.
What could possibly be wrong with clean air? No dust, no pollen, no mold spores or environmental pollutants, hmmm??
These people will tell you in the same breath they love their children, they would do anything for them… well how about dealing with reality and doing everything I your power to get air filtration in every classroom and public space that you have a statutory obligation or right to be in? If it’s good enough for parliament, Downing Street and other halls of power- it’s good enough for every single classroom and hospital ward to have the same.
