Our Verdict

Toshiba RAC-WK0512CMRU

EpiCooler

The Toshiba RAC-WK0512CMRU will be able to bring down the temperature in a room, unlike the EpiCooler. This is because the Toshiba is an actual air conditioner, with the means to remove heat from a space. In contrast, the EpiCooler is a plug-in fan that will just blow hot air around the room it's cooling.
