Inside an Air Purifier
This is a photo of a filter taken from an air purifier unit (just like the ones we’re planning to instal) in a house at only 300 metres from the school.
The filter was brand new only 6 month ago.
Currently we have a unit as a trial in one of our classrooms. Readings of the air have been taken before the trial and will be taken again afterwards. The results will soon be published on this blog.
