Hello,
I would like to be able to click on indoor air quality reports near me and see which self-report to have HEPA air filters vs those who don’t. That can help me get a sense of what the indoor air quality for me may be.
I think that data would be deceptive. It all depends on exactly how and where a “HEPA filter” is installed and where the sensor is relative to it. “HEPA filter” by itself isn’t very descriptive – is it a portable room filtering device, or is it installed in a central air system? How leaky is the structure? How long is the filter run per day? You’d need to answer these questions to get an accurate picture of the effect of the filter.
