Abstract
A filter and method are provided for removing contaminants from gas. The filter includes a frame member, gas-permeable supports positioned in openings defined by the frame member, and a biofiltration material in the supports including a filter substrate and a microbial population. Contaminants are removed from gas that flows through the filter as a result of contact between the contaminants and moisture contained in the biofiltration material and are degraded by the microbial population resident therein.
