Indoor air filter


The four-story biofilter is a jungle of ferns, ivy and other plants, collaborating to emit microbes that break down harmful airborne contaminants into water and CO2. This wall is self-cleaning- the pollutants are not absorbed into the plants, but broken down.

The biofilter was developed by biological researchers at the University of Guelph, including Alan Darlington, who now heads his own company, Air Quality Solutions, Ltd., to sell the living walls commercially.
