First, the quality of a modern American education.
Let's assume 2000sqft house with 8.5ft ceilings = 17k cu ft or ~500 m3, 1-0.1 μmol/mol ozone produces irritation to respiratory passages, so we need 1-0.1g total ozone left in 500m3 of house.
"170g of a highly reactive gas is generated over two days in a house full of organic materials. The windows are open and the heat is on; after what time will less than 0.1g gas remain?"
Make virtually _any_ assumptions and the answer could not possibly be longer than "minutes."
Mind you, I used very generous numbers and assumptions here. Mexico City averages over 0.1 μmol/mol and seconds of Mexico City air does not "totally destroy" anyone's lungs or cause you to cough up green phlegm.
In other words, with a few seconds of basic math and two basic facts about ozone it is trivial to see that the ozone is effectively gone. This guy has a university biochem degree and experience with organic synthesis? He's on there calling for an "atmospheric chemist" and thinking up ideas to fill the entire house with aerosolized cooking oil (!?!?!?) What is it that makes so many people today entirely incapable of critical thinking? Mind you, this guy literally once had a professor give him a hands-on demonstration of the rapid reaction of ozone - the sort of hint you would give if a student somehow failed the above question - and he still somehow couldn't get it after a week of Googling and reading "the literature."
How do we teach critical thinking?

Second, the modern synthetic chemicals we live with.
Ozone is always present around us, sometimes at quite high concentrations, depending on your environment. Obviously (... perhaps not always too obviously ...) it is always reacting around us. Most people own hundreds to thousands of pounds of modern synthetic materials. Innovative new chemistries. Formulas changed yearly. Those things are not static, they are off-gassing, they are reacting, they are releasing compounds unknown into the air we breathe. Just your mattress alone might have a hundred pounds of polyurethane foam, the precise composition of which is unknown to any one individual. Perhaps it is enclosed in a polyester cover, and then likely one treated with a fire retardant. Perhaps the corner protectors are recycled plastic of unknown origin, and then maybe they contain an odor-reducing additive. How do all these things react with the air around us? How do they interact with each other? I suspect that when we eventually study this better we are not going to like what we find - but for now, why do we allow plastics manufacturers to use us all as guinea pigs?
