You can do something against pollution
People who live in Bangkok or Chiang Mai face pollution during certain times of the year. It’s either traffic or the burning season and there is very little you can do to avoid the consequences of living in such environment. But you can defend your health at home in much more efficient ways compared to just relying on the aircondition to do the job for you. Because the particles in the air also reach every room in your house or condo. Even without pollution at high levels there is enough reasons to let an air purifier automate the task of defending your personal environment at home.
