EPA for that measure and then purple air is citizen scientists.
Purple air unfortunately read the pm2.5 a bit high. It's a well known issue with them. So EPA relies on their own monitors mainly. Also not all purple airs are placed in good locations (some read falsely high due to placement near vents etc ) and not all purple air are well maintained so will read high because of bugs in them,.other debris.

Air is not good today.
Government values for anything are always super optimistic.

The government values are very accurate. Much more accurate than purple air.

You’re right. 35 to 40 is fantastic and can’t get any better.

Unless you live in a vacuum chamber it's not going to get any lower. AQI wasn't 0 before the industrial revolution, a background level of dirt, pollen, and other particulates is still going to exist regardless of pollution.

It took a few tries but after several refreshes a reading came up... but got me wondering, who maintains the various sensors scattered around? Is it local government?
