Our Verdict

Frigidaire FFRA051WAE

EpiCooler

The Frigidaire FFRA051WAE, unlike the EpiCooler, is an actual air conditioner. The Frigidaire is capable of extracting heat from a room, effectively cooling the space, while the EpiCooler is a plug-in fan that does nothing to actually reduce an environment's temperature.
