I live in Bangkok. Buying a decent capacity dehumidifier (LG MD19GQGA1) was one of my best decisions ever. I don’t understand why they aren’t more popular here. Cuts down on the bill for A/C too.
Every place I have lived here the A/C has had trouble bringing the relative humidity below 60%.
Everywhere else I go (friends, shops) where there is A/C has it blowing hard at 24 degrees celsius, but it is still humid and thus uncomfortable. Xiaomi sells those portable temp/humidity meters for really cheap.
30 degrees celsius at 50% (or lower) relative humidity is so much more comfortable than 25 degrees at 70% relative humidity.
