One interesting thing about air filters is that many of the ones on Amazon can't be shipped to California. CA has strict standards for air filters apparently, so I always viewed this as a red flag. But it turns out those certification standards don't actually include filter effectiveness:

Not too long ago I looked up the legal standards for (US) butter grading. Turns out they are exclusively based on a taster's professional opinion of the butter's flavor.

This seems like a piece of regulatory apparatus we could do without.
