UV-C / hydroxyl generators or bust

Who in the world is installing UV in forced air systems without running an activated carbon filter to remove ozone? The guides I followed when I installed mine called this out multiple times.

All the tech in the world won't change anything if people don't focus on airflow and airchanges. Air needs to move and be replenished with air from the outside. Filters/UV/etc are just a bonus.

Fair argument, but let’s not forget that indoor air quality, HEPA filters, and upper air UV systems weren’t even allowed to be discussed as solutions to airborne transmission of viruses not that long ago. It was all about masks/no masks, remember? It’s a little unfair to say that things haven’t been studied, when it would have been career damaging to do so until very recently.

this is similar to anti-vax propoganda - setting an ever higher bar and saying we need that first there is no particular reason to think lab tests are not most of what we need.
