   Is my burning throat because of PM2.5/10? I moved here from Phuket in September. I haven’t purchased an air purifier yet I didn’t think I would need one till February or March. Is the air why my throat has been burning since last week. My sinuses too are acting up, burning eyes and I’m getting headaches at night. I thought I was getting sick but it just not going away. I just dawned on me it could be the air… PM2.5 was under 16 today.

      Most probably, my son and I have been sick recently too with similar symptoms. PM 2.5 of 16 is AQI 64 which doesn't bother me, I start feeling it at 70's and put on purifier at 80. Many people aren't as sensitive under 100 and will claim everyone isn't but they still are likely going to have long term affects by not protecting themselves adequately. How are you measuring the PM 2.5? The apps are great (AirVisual) but as they show where the sensor is, not you or your home, localized burning can make your exact location much worse in reality. As for you using a/c, I recommend checking your a/c filter and cleaning if necessary, you might be surprised and maybe grossed out by how dirty it is. Not sure where you are but the rice fields are being harvested now and the stubble is starting to be burnt off so could get much worse in the coming weeks but often it then clears a bit until February when it starts getting unlivable but around Christmas time during the last few years the air has been bordering on AQI 100 so a good N95 mask is a good idea to use when necessary.

      IKEA makes a really good, affordable air quality monitor, which helps me know what the air quality is inside my condo. It also monitors VOC.

      If you came from a relatively clean air situation in Phuket with onshore breezes, you might just be experiencing the huge difference between that environment and this one. CM barely gets any wind, being in a basin. Are you in the busy city part of CM? There is simply a lot of car and motorbike exhaust swirling in the air all the time, even if the official PM2.5 numbers are low and indicate clean air. You can think of that as "PM2.5" or think of it simply as smog.

   What is going on with the pollution in the North? It’s May 7th and Aqi well over 150+? I don’t mean to make another “burning season and pollution” post. Moreso I’d like to draw attention to the fact that it is MAY 7TH and Aqi is still awful in the North. Chiang rai - 160 Chiang mai - 177 Mae hong son - 191 In my experience and from what I’ve heard Songkran is usually the turn around point, and by May things should improve greatly. I don’t remember May ever being THIS bad as we approach the second week. It feels more like we are in mid March in peak burning season with no sign of stop than nearly the second week of May. Uhh.. what? What’s going on here? And why don’t Thai people protest this awful air quality? It seems like everyone is complacent with the short and long term effects. It also seems to have gotten WORSE as we move into May. My girlfriend suggested that a burning ban may have been lifted on May 1st. Furthermore, there have been pockets of rain here or there, but unlike the past, it has had almost 0 effect on AQI. This is a very confusing and brutal year and I have lost a lot of respect and love for Northern Thailand.

      2019 and 2016 were brutal. Compared to them the past few years have been pretty mild. 2019 especially was bad , standing in front of a big hotel you could only see about 5 floors high on some days.
