No! The design of Portacool portable evaporative coolers allow for complete molecular evaporation of water – what the heck does that mean?!?! Our engineers are so smart…in normal person language that means only a pure, clean stream of air is blowing out. Some people might say that they do not agree because of the smell – this however is only aromatic molecules that have evaporated along with the water. Our products do not, in any way, allow harmful chemicals to be evaporated into the air stream.
