Cleaning products are considered pollution by NASA which is why they came up with a list of plants to clean the air in their hypothetical moonbase. You also have energy efficient homes which dont do the air exchange as much allowing for a build up of pollutants in the home and office but not all of them get considered pollutants. And just because you cant see the particulates like soot, doesnt mean the air is cleaner, its just different chemicals that still have a negative effect on the body. Look into Dieselgate to find out about those.
I agree, but I’m surprised that GP said that people in the West have lower IQ because pollution is vastly superior. If proven, it would help me choose a country to emigrate, but I recall dodgy plastics in Indonesia and smog in China, and I’m quite sure the less-tertiary countries have more pollutants.
A well-designed energy-efficient home has plenty of air exchange. It's just that the fresh air comes in at one place, gets filtered, and exchanges heat and humidity with the outgoing air in an ERV system.
