Where can I get a good PM 2.5 meter in Chiang Mai or perhaps online if need be. I want to know how bad the smoke actually is in my house. Thanks guys.

Google Banggood, but will be at least 2 weeks shipping.
Otherwise check out Lazada Thailand.

Yeah I see there on Lazada but there's lots of different price ranges. Any idea what's a good one that doesn't have lots of unless features and isn't more junk from China.

Download the AirVisual app for your mobile (free). It's the "front end" of lots of their hardware units in the whole world. You can buy the unit from the app (US$ 250 approx if memory serves), and your unit will then contribute to the data the free app shows. Swiss stuff, no Chinese maybe's. 😉

I bought this one last year https://www.lazada.co.th/products/pm25-xiaomi-smart-air-quality-monitor-pm25-detector-pm25-xiaomi-jcy01zm-i294862517-s495810444.html?spm=a2o4m.searchlist.list.3.303348ffQbBAGp&search=1

 

I would like to think it reads high 🤔 but it appears to be very accurate :shock1:

We are in the outskirts of Udon Thani, 20k from centre and its been 140 - 221 for the past three days!

Am glad nobody asked me this question in the local coffee shop. I'm afraid I wouldn't have had a clue what they were talking about.

Wow, that is almost half the price of an air purifier by the same brand (which has a detector inside as well).

Rule of thumb is indoors is 50% less than outdoors but then Thai workmanship often leaves gaps in doors and windows, plus how often you open and close doors and windows, etc. So probably indoors will only be 30~40% better than outdoors. 

Some of the PM meters are using the wrong laser sensors and are including PM10, etc. I suggest buying one from overseas that you can trust and has a guarantee with. 

I bought a PM2.5 on Lazada but when I took it apart I found the sensor was a combined PM2.5/10

I'm not so serious about it though so didn't worry me that much plus it was cheap, 700bht. 

Invest in an air purifier but even with a purifier in a small room I can never get it lower than 60 PM2.5 🙁

Maybe you need a new filter?  Have you tried putting your sensor right next to the outflow from the purifier?  Mine gets down to 12 pm2.5, & the room gets down to around 15.  20sqm 3m ceiling.

or maybe you have to remove the plasik from the filter first ... or your 60 are AQI ?
