This device is what’s known as an evaporating air cooler. Another name for it is a swamp cooler. Basically, it sucks in hot air through the back and then passes that hot air through a moisture chamber. As the air comes out the other side, it evaporates and thereby dissipates the heat, leaving cool air to blow about the room.
This type of cooling system is seen as an affordable alternative to air conditioning, which tends to consume a lot of power and cost you a significant amount of money.
“It’s the personal space cooler that transforms hot spaces into cool refreshing places for just pennies a day,” the device’s commercial says.
In fact, the commercial shows someone shooting a hair dryer’s 96-degree air into the back of an Arctic Air and 72-degree air blowing out of the front of the device. It also shows someone laying poolside with the Arctic Air blowing on them.
Using the Arctic Air Ultra requires filling its water tank, then plugging it into either a wall outlet or a USB charger. According to the product’s website, it can run for up to 10 hours on one tank of water.
