Nedlaw Living Wall Biofilters are the most rigorously tested living walls in the world. They are here to do a job, and that job is increasing building performance while looking fantastic. Our walls are considered “active” because they pull polluted air through the room system, as opposed to “passive” walls that sit pretty like a potted plant. Both active and passive walls feature root environments, but passive walls work very slowly.
If you are vetting plant wall products, you’ll find that most companies make statements about air quality. In this business, there are well accepted factoids about plants having a positive impact on well-being, but extending this supposition to improving air quality is quite opportunistic.
Plants alone do very little to improve air quality. Our Science section explains how it’s actually the exposed roots of plants that do the dirty work. The root zone is the biofiltration zone. We are working to continuously improve the efficiency of VOC removal in order to maximize the clean air our system provides.
Since they are engineered for optimal filtration, our Biofilters can clean 100 square feet of interior space (assuming average floor height) with every square foot of living wall. To put that in real terms, consider that the 3 ft x 7 ft Biofilter in our board room, connected to the HVAC, is cleaning the air for 2,100 square feet of office space. It is metabolizing the smell of microwaved lunches, off-gassing furniture, bathrooms, the truck garage next door and the farms down the road. Odour removal is a great perk!
