FAQ for portable evaporative coolers buyers:

Can you run an evaporative cooler without water?

Running the pump without water will overheat the pump, causing it to burn out. If you run out of the water, most evaporative coolers will run the fan without water, but this is for recirculating air and won’t truly cool it.

Do portable evaporative coolers need to be vented?

Evaporative coolers don’t require venting like portable ACs, but the air forced out will still require an exit path in order to ensure sufficient cooling. This can usually be accomplished with an open door or window.

Can you leave evaporative cooling on overnight?

You can keep it running 24/7 until the hot spell ends. You can turn the aircon on to fan only overnight if the night temperatures are in the mid-20s or keep it running overnight if the temperature is close to 30 degrees.

How much water does an evaporative cooler use per hour?

Evaporative coolers use both electricity and water. How much water is used depends on the humidity of the day and the fan speed that the unit is set to operate on. A portable unit might use up to 4 liters per hour while a central system could use as much as 25 liters per hour.

How often should evaporative cooling be serviced?

The recommendations for how often evaporative cooling should be serviced depends on the brand and model. The general recommendations to ensure maximum efficiency may range from checks on an annual basis to having the cooling system checked every 2-3 years.
