Tesla is (a) solution

For those of you beset by the smoke from the Canadian wildfires, Tesla’s Bioweapon Defense Mode is a very effective solution, at least at the individual level. I retreated to my Model S when California skies turned red in 2020, and found that even the smell of smoke was undetectable within a minute or so. Note that this feature is not available in the Model 3, since there’s no room for the huge HEPA filter.

Just another unexpected benefit.



A significant and ongoing expense to replace…

A couple of hundred dollars every four years is “significant and ongoing”?

(BTW, my original filter still works fine after 5.5 years.)

Also, I see a DIY drop-in replacement is $65 on Amazon.
