I am here to review about Voltas 70L MECH VA- D70M desert Air Cooler. The service is not that good but okay. It cools air for a limit.Cooling capacity is 30W. Power 230V / 50V .Room size 300SqFt. Air throw distance 22Ft. Double Air Blower Function. Honey Comb filter makes Air cooler more reliable. Price of this Air Cooler is very reasonable. Color which I bought is white and looks good. Its sound is bit louder and disturbing as well.
