Swamp coolers are a low cost alternative to traditional air conditioners, and are much better for dry environments that could use a little more moisture. Check out some of the best swamp coolers, also known as evaporative coolers, which are cheap to buy, and cheap to operate, and will keep you nice and cool.

If you live in a hot, dry climate, a swamp cooler may be just the thing to keep your home cool and your electric bills at a reasonable level. Read on to see if this solution will work to keep you more comfortable for less.

Evaporative (swamp) coolers are an energy efficient way to cool a house in dry climates. They consist of a water reservoir 3-5 inches in depth. This water is sent, via a water pump, to a water distributor, which passes the water over a wet cell or pad. This wet cell is basically a large cardboard air filter. Air is pumped through this wet filter, and this water cooled air is then pumped into the house through normal duct work. Keeping an evaporative cooler working at optimal efficiency takes vigilance, but is relatively easy overall.
