Strong agreement. Minimum safety standards for indoor air are as important as minimum safety standards for water and food.

For those interested: the International Society of Indoor Air Quality and Climate maintains a database of indoor air quality standards worldwide [1]. It lists standards by country, and allows you to filter by pollutant. CO2 is a commonly proxy for ventilation with values <800-1000ppm typically considered to be “good”.

For the US specifically: the recently published ASHRAE 241 standard [2] provides updated guidelines for indoor air quality. This provides stronger guarantees than the weaker ASHRAE 62.1 standard [3], as it specifically focuses on reducing aerosol-based transmission of pathogens such as (but not limited to) Covid-19 and H5N1.

It's even more important if this finding [1] (press release [2]) turns out to be true, namely that the amount of carbon dioxide in the air is not just a proxy for air quality, but that having less of it actually actively destabilizes virus particles.

Also, portable air cleaners seem to work pretty well [3].
