That's a really good idea. I was planning to buy one for a few hundred dollars, but I should just do this instead. The burning season is really bad in Chiang Mai (lots of smoke in the air for about 2-3 months), so it's good to stay indoors and have an air filter.
Off topic, but hey so I just moved to Chiang Mai. Do you think it's worth even sticking around here during that time? I was thinking about just heading to Bali instead. Not sure how bad it really gets.
It's really awful, especially if you're sensitive. Some people aren't bothered by it too much, but it really affects me, so I try to get away. We have some pets, but it hasn't been too hard to find a house-sitter. (Although I always feel a bit guilty, and try to be honest about the smoke.)
I think we'll move to a new city or country in the next 12 months. I don't think it's wise to go through burning seasons once a year for a few decades. (It's actually the only reason we want to move, otherwise Chiang Mai is an amazing place to live.)
Bali would be a good option, or even the south of Thailand if you have some more time on your visa. Koh Lanta is great.
