Thanks! I may be thinking about it too much from the consumer perspective of owning a condo in a 100-year-old building, where the noise of filtration is a major drawback and the costs of a broader modernization of HVAC systems would be considerable.
I haven’t polled grocery store owners, but an owner would bear all the costs of improving air quality yet may capture few of the economic benefits. Although customers would care a lot in a pandemic, they probably wouldn’t otherwise care in a way that increases profits—and managers are incentivized toward short-term results. Cynically, most of their employees may not have paid sick time, so the owner may not even realize most of the benefit from reduced employee illness. (Of course, regulators could require compliance—but that’s not an awareness problem. So maybe the candidate intervention is lobbying?)
Just get a room air filter for your condo. There are different models and they are usually quite quiet unless on the highest setting. I can’t hear mine on the two lowest settings (up to 100 CFM). UVC doesn’t remove small particulates, which is the most serious air pollutant of concern from a health perspective for most homes.
Commercial buildings have to comply with locally required codes and standards. Code authorities could adopt some or all of ASHRAE Standard 241 in their jurisdiction just like they do with ASHRAE Standard 62.1 (ventilation) and 90.1 (energy).
