MRT - Misty Railway Transit

There is something new in the MRT North Avenue station (not sure, however, if all the stations have it.) Misty blowers that, at first, I thought was something like in the movies when a pipe gets a hole and releases poisonous gas. But, when I took a closer glance, they were really built-in tiny sprayers to emit mists.

I still am not sure if they are mists to keep the station cool, but it seems like it. Wasn't able to check the news last night, so maybe tonight it will be one of the headlines. 

In all fairness, at first, I was worried, then I looked around they were everywhere, then I thought... "Cool..." Albeit, I didn't feel it, anyway, I hope it helps.
