The Arctic Air Pure Chill cannot manage the summer heat, can barely cool a room or an office as advertised. The so-called portable cooling unit is a swamp cooler and cannot replace an AC unit or use as a substitute. They operate on "water curtains" which had to be filled with water and then placed in the freezer before inserting into the unit, rather than filling the unit with water as advertised.

Once inserted in the unit, the frozen water curtains last only about 30 minutes before they need replacement, and the cooling effect will not be adequate.
