    It does not have to be close to a window or doorway, but it will help the unit to work more effectively, since it will pull this cooler air in.

  • Does MC37 have to be vented out a window or door?Because manual day it does to work efficiently.

  • Where is this made?

    This evaporative cooling unit is made in China

  • I have three questions. First, is this appropriate for a residential 600 sq foot outdoor deck in Long Island and if so, what type of degree drop should I expect. Second, where is it made, and third, what is the cost. Thank you

    If your deck is completely closed in, this unit will help keep the area size cooler (based on an 8' ceiling on the enclosed deck).  If it is an open air deck, it will only cool those standing in front of unit. Temperature drop is based on the amount of humidity in the air. This unit can offer as much as a 15 degree F. temperature drop if humidity is low.
