Hi Robert, thanks for answering. I would like to add two more points to what you already said:
1. To get more bang for relatively little organising, why not get just a few air filters for those rooms which are most crowded? 100+ air filters seem indeed like a lot (I calculated with 12).
2. It would perhaps be easier to get data on the health benefit related to reducing indoor air pollution. There are plenty of studies on this, I will try to find a good one. This alone may be sufficient to justify the expense. Reducing respiratory diseases would come on top.
