Question:

How Often Do I Need to Change Out an Evaporative Cooler Pad?

 

Answer:

This depends on the usage of your evaporative cooler and the quality of the water being supplied to the unit.

  • Aspen pads are changed at the beginning of each season (possibly more, depending on the scale or mineral deposit build-up on the pad).
  • Cellulose (or CelDek) pads can last up to 3-5 years before requiring replacement.

Refer to the owner’s manual of your unit for detailed instructions and a maintenance schedule.
