Funny thing is that those air filters are reducing the exposure to PM2.5s. And it is PM2.5 particles that are associated with an increased risk for dementia.
Unintended consequences are not always a bad thing. I wear a mask now through much of my work day. My home, office, and where I workout all have HEPA Filters now. I monitor the AQI, and if it's a 'shitty air day' I will either do stuff inside until it clears up, or wear a mask outside. The problem we are definitely not solving is the fact of air pollution. There are mountains to the south of me, and it used to be a rare day when the air in between was hazy. Now it's a rare day when the air is not hazy.

so what you’re saying is that by attempting to fix one problem, they ended up fixing another?
