Water when it evaporates is just water vapour, so the "dirtiness" of the tank should still stay in the water...
It is just like distilling water so that we can drink dirty water if desperately stuck in the desert (learnt that in secondary school, right?)...
So I think, there is actually not much ground to it... Moreover, the air in an air-con room is actually very dry, so some moisture is good... Your sinus is probably due more to the air-con alone... Since our atmospheric humidity is definitely higher than your moistured air-con room...
That's my take on the situation... Me no medication doc...
