We are talking about AIR. We can not see how good or bad the IAQ is, but having sensors will at least give us some indication of how well it is. In addition, we recommend bringing in a 3rd party engineer to test the air before and after improvements because the engineer has the ability to give you more in-depth data like ion levels, formaldehyde, particle counts from .3 microns to 10 microns. If your supplier is concerned about you bringing in a 3rd party engineer – you should look for another supplier. IAQ investments should be able to be quantifiable – not just theoretical. #indoorairquality #studenthealth #teachers #pandemic
