DIY Air Purifiers for classrooms?
Mon, Oct 28 3:23pm

Hello Bay Farm families, 

We have seen reports of people making their own air purifiers. If anyone is interested in trying their hand at making a DIY air purifier for a classroom it would be appreciated. We are not sure how long this bad air will be around and our open format campus means that our classrooms have increased outdoor air exposure.

According to instructions all you need is a  a 20" box fan, with a MERV 13 furnace filter taped to it. All of the should cost about $30. Supposedly this will remove >90% of the particulates in the air in about one hour. 

Many thanks,
