Best hotels for clean air in CM?

[Poopyface]

Hi

I'm looking for budget hotels with some sense of clean air for the burn season.

Clearly fan rooms won't cut it.

 

Last time I visited CM, I spent a night at the Baan Din Ki, and I remember thinking 'this would be a good place when the air is bad.'

It's in the old Central mall, windows sealed, lobby air conditioning, everything way indoors.

 

I can't think of any others like that tho, and I don't want to spend 1000 baht every night.

 

Any recommendations on hotels with sealed windows / air conditioning lobbies / places the wind doesn't whistle through, preferably affordable ones?

 

Thanks!
