A look at indoor bio-filters and the technology leader in living green walls. Fully automated, these hydroponic living structures clean and purify/ detoxify our breathing air with three levels of filtration. The technology leader in living wall technology.

1. Indoor Air Biofilters
Giving you . . .
Clean air, naturally

2. INDOOR AIR BIOFILTERS:
Changing Our
Indoor Environment

3. We are an
indoor species
Improving the indoor
environment with natural
systems
We live in a very
artificial
environment
Rely on
mechanical
systems

4. Indoor Air Quality
• US EPA has ranked indoor
air pollution in top five
threats to public health
• One of the largest health
risks in the United States

5. Traditional Air Quality Control

6. Alternative Approach

10. Clean Air Delivery Rate
• Recent study with major Canadian University
• Biofilters provided up to 100 litres
of clean air per second per square
metre of biofilter

14. The Nedlaw Indoor Air
Biofilter
Beneficial microbes on surface of the
plants degrade pollutants
……NOT the plants themselves

15. Typical Construction
Vertical duct
Perforations to let air in
Air moves up inside duct
And into manifold
Then back to HVAC
Manifold connected to
return air duct of HVAC
Cleaned air returned
to space

16. Installation of Growth Media
Growth media fastened
to peaks of diffuser
Installed as two
separate layers

18. Air Handling
Sites with built in fan
Sites connected to HVAC

19. Physical Improvement in IAQ
• Improved indoor air quality
– lower concentrations of
indoor pollutants
• No disposal issues
– contaminants broken into
benign constituents
Cambridge City Hall,
Cambridge , On

20. Improvement in
Indoor Environment
• Psychological impacts
• Reduced absenteeism
• Improved productivity
• Acoustic value
…Green the Indoor Space and
Improve Building Performance
Corus Quay - Toronto

21. Venues
University of Windsor
System will fit a wide range
of different venues
We usually just think
of Atria
But also Industrial and
Agricultural applications
and recreational
and retail

22. Gathering Places
Guelph Humber
University
Royal Botanical Gardens - Hamilton
The living wall biofilter creates
a natural gathering point
within the building.
Create a sense of community
in our hurried lives
…. A place to celebrate
…. A place for quiet reflection

23. University of Waterloo
Centre for the Environment
Passage Ways
…. Raising spirits
Mohawk College,
Hamilton

24. Passage Way
Direct Energy Centre, Toronto
Assist in the flow through a space

25. The Possibilities Are
Endless
Extremely efficient piece
of machinery that just
happens to look great
