Abstract
An air filter assembly for removing particulate contaminants, chemical contaminants, or both, from an incoming dirty air stream. The resulting filtered or clean air is supplied to catalytic equipment, such as a fuel cell. The filter assembly can include a physical filter portion for removing physical or particulate contaminants, a chemical filter portion for removing chemical contaminants, or can have both portions.
