An evaporative pad comprising a plurality of layers of highly absorbent
slit and expanded wicking papers and at least one layer of slit and
expanded non-absorbent material carrying a coating of adsorbent particles
bonded to exposed surfaces of the layer of non-absorbent material
disposed between a pair of adjacent wicking layers in the pad. The
wicking layers and non-absorbent layer coated with adsorbent particles
are disposed in parallel overlying relationship to one another and bonded
together to form the evaporative pad.
