Love how you pulled this research together.

It’s astonishing to think we take in ~11,000 liters of air a day—so even “moderate” PM2.5 exposure adds up.

The ultra-fine particles are small enough to cross the blood–brain barrier and settle in brain tissue (both via blood stream and olfactory pathway), which makes indoor air quality just as important as outdoor.

For me, a purifier with both HEPA and activated carbon (to catch VOCs from furniture, paint, also chemicals of exterior origin etc.) is a must-have, and I have several of these at home!

Kat, after reading The Lancet paper, I decided to buy a second HEPA air purifier that removes >99% of particles .1 micron or larger. There's a lot of different brands, at different price points, offering different features. And so it takes time to read the reviews and make an informed choice. But I believe it's worth the time. The long-term, accumulated damage even from years of cooking healthy lean meat, eg, can be significant. Good on you for having several air purifiers.
