Is the CO2 accumulation entirely due to human (or I suppose animal) respiration? So it will typically be worse in small houses with lots of people (holding other factors, like ventilation, constant)?
In a modern house, with no open fires, lead paint etc, what “household air pollution” might there be?

More than you would think—a lot from kitchen, some from (newer) furniture, some faecal matter from mites, house dust which is largely human skin, cleaning chemicals, ozone, positive ions (the bad ones) from laptops especially Macbooks, mould spores, etc.

but in may countries the original source of ‘household’ (indoor) air pollution is actually from outside the home:

I bought two HEPA filters to help protect others during a home isolation, but I also had in mind that it would be useful afterwards!
