Back in 2020, the AQI at my house in the SF Bay Area hit 800. (I was directly downwind from the CZU Lightning Complex fire.) To say that was bad was an understatement.
I had to seal up every door and window to my house with plastic, then put three 1200 sq. ft. rated HEPA filters in a single bedroom to get the air quality in that one room down to livable.
That's also when I discovered the real difference between an N95 mask and a N100 respirator.
- crazygringo 3y agoHoly crap. Today I watched it go from 200 to 400 in the space of an hour and the difference was so much more than I ever would have expected just from doubling, 200 was an inconvenience but 400 was a real yikes. I can't even imagine what 800 must have been like.
