I work at a place that sells these. The kind you want are particulate respirators/filters. These are the real deal.
I had to deal with some really bad wildfire smoke in my region last summer. So bad they closed the national parks. (which is rare here) (Side note, my brother wanted to go freaking HIKING in it…like HONEY, that’s how you die.) and it wasn’t as bad as what I’m seeing w/ Cali. So stay safe and protect your lungs.
