Wow. Schools being told they're not allowed to use air purifiers bought by parents, because they're "not needed" based on an "audit".

BUT the audit was done when schools were closed. So they haven't actually measured CO2 with students present! 1/🧵

Principals are being told that air purifiers could make air quality worse if not maintained properly.
But Prof Lidia Morawska says it's "strongly recommended that schools that do not have ventilation systems capable of keeping indoor particles down be equipped with air purifiers"

If you're wondering who Lidia Morawska is - she's one of the world's top experts on safe air and COVID.

Vic purchased air purifiers for schools, but NSW didn't. There are now politicians and bureaucrats scrambing to justify that somehow NSW kids don't need them.

They're stopping schools from using them even when already purchased, despite experts saying they're needed.
