The setting i used it in had humidity of around 5060 and as such this worked well enough to provide cool air

Since the basic principle is to humdifiy the air it really wont work all that well in a humid enviornment where the air is already humid and in fact you will have humid air being constantly blown around

I havent noticed it

Tip use cold water for best results there is plenty of debate surrounding this but in my experience cold water worked betteressentially this will work fine to cool a single person in a confined enviornment
