Morphology

biofilter = filter (semi-transparent) = bio + filter

The structure is clear as bio- + filter, but the term is somewhat technical because bio- here means living organisms rather than a fully everyday meaning.

Etymology

The word biofilter comes from bio- meaning 'life' and filter meaning 'something that removes unwanted things'. A helpful image is a 'living filter' where small living things clean water or air. So a biofilter is a filter that uses living organisms to remove pollution.
