I saw this on TV and thought it was a nifty idea, so took a look at it.

It’s basically an old-fashioned “swamp cooler” that cools air through the evaporation of water. The temperature of dry air can be dropped significantly through the evaporation off liquid water to water vapor. This can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of adding more moisture, which makes the air more comfortable for building occupants.

This works great in areas like the desert where the air is very hot and dry, and doesn’t work well in places like Florida and the South, where the air is already very humid.

To use the arctic air, you just fill it with water and plug it in. The unit pulls in warm air and produces cool air within a small area around you. Pretty simple. No Freon or other toxic refrigerants. You’ll also save money by cooling the space you are in, rather than the entire house.

My only reservation is that it’s made from plastic. Customer service couldn’t tell me the type of plastic, so I don’t know if it outgassed or not. If anyone has tried one of these, would you comment and let us know?

And a caveat: if you are going to use this, please use purified water as ordinary tap water would evaporate chlorine and other volatile chemicals into the air.
