Evaporative Coolers Buying Guide


Living in one of the hottest countries in the world, it’s crucial to find ways to beat the heat during the summer months. Aside from air conditioners, portable ACs and fans, another option is evaporative cooling. So, what is evaporative cooling and how does it work? We bring you this guide on what you need to know, and review some of the most popular brands on the market.

How does an evaporative cooler work?

Evaporative coolers

An evaporative cooler cools air through evaporating water. It consists of a fan and a water-soaked pad where the fan draws warm, stale air inside the unit and then passes it over water-moistened pads to be cooled. Since the cool air is continually circulating and creating a breeze, your ambient temperature can feel a few degrees lower than the actual temperature in the room. It’s like when you get out of a pool on a hot day and immediately feel a chill as the outside air cools the water on your body.

Will evaporative cooling work for me?

Aside from cooling a room, evaporative coolers also add humidity and moisture to the air, making them ideal for areas that are dry and hot. According to air con manufacturers, evaporative coolers don’t suit high humidity environments, such as QLD, NT and northern WA, but may be more suitable for southern, less humid Australian areas, like ACT, VIC, SA and TAS. The map below identifies which areas experience dry heat over summer.

Climate Zone Legend

The above map shows the eight climate zones, with Zone 3 and 4 being classified as hot and dry.

  • Zone 3: includes northern central Australia from Carnarvon on the WA coast, encompassing Newman, Alice Springs, Tennant Creek, Longreach and Charleville to the QLD hinterland down to 28 degrees south, but not the coast.
  • Zone 4: is southern central Australia from the WA hinterland across most of inland SA, NSW and VIC, encompassing Yalgoo, Warburton, Coober Pedy, Whyalla, Broken Hill, Mildura, Bourke, Tamworth and Albury-Wodonga.

Evaporative Cooling vs Air Conditioning

Split-system air conditioners are divided into two units – indoor and out. While evaporative coolers also have two components, the process is different. Split-system ACs replace the hot air inside with cooler air from the outside, plus use refrigerant gas to reach the desired temperature inside the home quickly. It works in any climate, especially humid areas unlike evaporative coolers.

How much does an evaporative cooler cost?

Evaporative coolers typically range in price from around $100, going up to close to $400. These are the brands that we consider in our guide and the prices you can expect:

Evaporative cooler maintenance

All types of air conditioning require systematic checks. Apart from regular maintenance, evaporative cooler pads will need to be serviced. According to some manufacturers, pads can last for up to a year, while others boast a long life of seven years, but this does depend on water quality and local weather conditions. You should consult your instructions manual upon purchase.
