Living Air Filter
2021

Algae has become a popular medium for air filtration in the field of Biodesign. But what other plants can we partner with to filter the air within our homes? What mediums for filtration could be possible without the use of pumps or electricity? Are there ways we can use design to imitate structurally how air is being filtered on a microscopic scale, thus learning more about the process? 

After months of research, lichen revealed itself to me as a plant partner. Lichen is a “species” comprised of both algae and mycelium working in unison. Lichen acts as a sieve, so it is very sensitive to air pollution, as it will absorb everything that passes through it - but it can also revive itself countless times with the proper care. Therefore, the piece not only cleans the air in your home, but the lichen’s health can indicate potentially hazardous air quality.

The structure’s design is based on the lichen’s microscopic form. The piece harnesses the concept of wall panels to mimic the lichen’s ideal conditions on the bark of a tree, with air flow and moisture constantly moving past as you move through your home.
