This really is an air conditioner on wheels. The Whytner ARC-14S has full thermostatic functionality between 61 and 89 degrees Fahrenheit. You can connect the exhaust hose to the window mount (included) and have a fully functional, thermostat-controlled window AC unit.

The swing fan louvers were a nice touch as they allow you to get a concentrated flow of cool air in virtually any direction. There are actually ice packs that you can put into the Costway Air Cooler and Heater that make the air really cold so it was pretty effective even on the hottest days of summer.

  • Built-in air filter

Instead it is an evaporative fan which means it uses a water reservoir to cool and circulate the air that passes through it. This is a smaller unit but we found it to cool down rooms up to 450 square feet very effectively. Like the first air conditioner on our list, the Honeywell CSO71AE has an activated carbon filter to help purify the air.

  • Very affordable
  • Can be used as a humidifier
  • Reduces the amount of dust particles in the air
