Abstract
An ozone and odor removing filter media having a filtration layer and a supporting layer. The supporting layer includes activated carbon fibers or powders, or both, incorporated within the supporting layer. The activated carbon particles can be added to the supporting layer by combining them with binder in a slurry and extending the already-formed supporting layer through the slurry. The wetted layer then extends through opposed rollers to remove all but a desired amount of slurry. Alternatively, the activated carbon particles can be added to the mixture when forming the supporting layer.
