Biofilter - Wikipedia
A biofilter is a bed of media on which microorganisms attach and grow to form a biological layer called biofilm. Biofiltration is thus usually referred to as a fixed–film process.
Biofilter - an overview | ScienceDirect Topics
A biofilter is a mixture of wood chips and compost, which supports a good volume of microorganisms. The contaminated air is forced into this material which is ultimately converted into carbon dioxide and water with the help of microbes. To develop a successful biofilter, a proper and appropriate selection of biofilter media is needed.
