Choosing a living wall can be an overwhelming decision not only because of the many options available. Splashing green into interiors is not difficult – if you are looking for a temporary decoration, these green walls may do the trick.

If you are inspired by the idea that nature can actually work with us and improve building performance, we encourage you to look for a system that has deeper roots, figuratively and literally. We invite you to explore our resources to learn about how hard Nedlaw biofilters work!

There is peer-reviewed research demonstrating Nedlaw Living Walls’ effectiveness at processing air pollutants like VOCs, which is why we refer to them as Biofilters.

We are in the process of compiling over 20 years of research into documents and case studies. Here are several that are now available. Please contact us for information on any specific area of interest.


We have completed research studies in conjunction with the University of Guelph. You can read the full reports using the following links.
