Personal Air Cooler Vs Air Conditioner

A personal air cooler or “mini air conditioner” is actually an evaporative air cooler, a.k.a. a swamp cooler, which pulls the warm air from your room and runs it through the cool water it has in its tank. That’s how it manages to decrease the overall heat in the room. Mini evaporative air coolers are a more affordable option, but aren’t optimal for humid spaces.

On the other hand, an air conditioner absorbs heat by utilizing a refrigerant fluid. It releases cold air to decrease both temperature and humidity in the room. This process requires a lot of energy and can make your electricity bill skyrocket.
