Good question, VocalNeal.

I'm not happy with this table, but you might check it yourself:

Another good read:

Some screenshots?

You're welcome.

It looks somewhat obtuse and something we have to believe because the boffins say so?

I=  [(Ihi-Ilow)/(BPhi-BPlow)] (Cp-BPlow)+Ilow,

It's not a question of believe.

Everyone should be able to read a PM2.5 meter.

Here and now - it shows between 25 and 30 ug/m3.

I think there are no other air pollutants to consider, 

so the AQI might be between 78 and 89.

OK?

By the way, a village nearby:  AQI 81

Phrae city(20km)  AQI  152-165 

(https://aqicn.org/here)

Some models:

Lampang/Mae Moh isn't too far from Phrae,

Phayao, Chiang Rai, so I think this table

might be interesting for all.

Today began Dry season. Time to burn Thailand in a non-stop mode, until the raining comes. 
 

Today in Mae Taeng;

My shield; Air purifier and air conditioner in non-stop mode. ????
