Sorry but you don't know what you are talking about - do u even know what an n95 mask is and the type of pollution that is/was prevalent in Bangkok???
Yes, it does depend on the type of pollution - do u have any scientific background or any credentials that allow you to make such a rash statement? Of course any mask is only good if it is used correctly (which, sadly most people don't).
