Unless the author is not only a scientist but a really good one, I cannot personally believe any of this material.

If particles were as essential to health as claimed, smokers would have a much much shorter life expectancy.

Agree. S/he is selling air filters, so the intention is obvious to me here.

Anyways, it's an interesting read but I'll take it with a grain of salt.

I dont see any evidence they are selling anything. No links, or even names of products on the various pages about air filters.

> It's not just about life expectancy, but life quality. I think we'll one day be surprised just how many mental health and chronic illnesses are significantly attributable to air pollution, in all its forms.

lol. smoking reduces your life expectancy by 15% on average.
