CELDEK & WOODWOOL PADS

The two main types of Filter Pads available in Australia are Woodwool and Celdek. Both types of pads are designed with high water-to-air contact area to promote water evaporation.

Woodwool filter pads are made of shredded wood slivers. The wood slivers are packaged into pads ranging in thickness between 3-5 cm and fitted to the evaporative cooler on the inside of the louver. Woodwool evaporative cooler pads are commonly used in older model air conditioners. Woodwool filter pads normally last 1-2 years depending on water quality.

Celdek filter pads are made from cellulose sheets in a honeycomb structure. Woodwool filter pads are being replaced by Celdek filter pads as they have a higher saturation efficiency and much longer life span. Celdek filter pads normally last 4-5 years depending on water quality.
