At airmid healthgroup ltd our mission is to prevent ill health caused by exposure to indoor air pollutants. To achieve this goal we have assembled a unique multidisciplinary team of Clinicians, Industrial Hygienists, Occupational Health Advisers, and Specialist Laboratory Scientists in Mycology, Virology, Bacteriology, Allergy and Immunology. This slide deck refers to our Environmental Test Chamber with modified ASHRAE type 52.2 Test Rig. To find out more contact Graeme Tarbox gtarbox@airmidhealthgroup.com or visit www.airmidhealthgroup.com To help clients with products and services for the built environment improve their customer offerings through health related innovations and marketing. The Airmid mission is to create value through a number of collaborative strategies including field research, environmental test chamber studies and licensing our own intellectual property. By specialising in studying how allergens, viruses, and other ultra-fine particles spread illness and disease in buildings we are a leading authority in aerobiology and bio-medical research. Our clients succeed by making the built environment as healthy as possible.

Indoor Air Quality - The Facts
• The World Health Organization (WHO) estimates
that greater than one building in four has indoor air
quality problems
• Indoor air is more polluted than outdoor air (5 to
100 times) with 90% of our time spent indoors
• Indoor Air pollution has been ranked as a high
priority health risk – it is ranked 5th as a cause of ill
health worldwide
• To breathe healthy indoor air is considered a
fundamental right by the WHO

8. Main chamber
• Purpose built ASTM standard chamber
of 28.5 m³ capacity.
• Stainless steel construction
• All materials complying with low VOC
emission requirements.
• Air Change Rate controlled within a
range from 0.38 to 60 Air Changes per
Hour (ACH).
• Temperature and humidity levels
controlled across a wide range at all
ACH rates.

9. Conditioning
• Test room temperature and humidity are
maintained in standard laboratory
conditions
• Ability to control temperature between
18 to 35° C and 40-65% relative
humidity.

10. Real Time Aerosol Monitor
• Real time aerosol monitor capable
of measuring airborne particulate
• Laser Particle Counter (0.3 – 10
microns)
• Condensation Nucleus Particle
Counter (0.15nm – 0.1 micron

11. • Comprehensive particle
counter monitoring
• State of the art air sampling
techniques
• In house Laboratory
Analytical Testing Services
• including PCR (Virology,
Mycology,Bacteriology) and
ELISA (Allergen)

14. Specifications and construction of
environmental test chamber
• 16' x 8' x 8' (28.5m³)
• Constructed according to ASTMD6670-01 and
ANSI/AHAM AC-1:2006 standards
• Stainless steel interior
• All materials complying with low VOC emission
requirements
• Two observation windows on one side and
door, Externally sealable ports
• Internal electrical outlet and fluorescent lighting
• Capable of 0.38 to 60 air changes per hour
• Controlled air flow, temperature, and relative
humidity
• Ability to maintain temperature between 18
and 35° C and 40-65% relative humidity.
• Positive pressure entrance air lock lobby
• UV down lighters

15. Air handling and cleaning
• The chamber is served by supply and extract
air handling units with re-circulated air and
make up fresh air.
• The supply fan is capable of variable speed
and the chamber has motorised dampers with
shut-off seals on both supply and return ducts.
• The supply and exhaust air is HEPA filtered
• Adjusting the fan speed and dampers enables
the air exchange rate of the chamber to be
reduced from 60ACH to as low as 0.38ACH,
equivalent to a passive house. .

16. Example of test apparatus
• SKC Biosamplers
• Biostage impactors
• Sidekick pumps
• Laser particle counter
• Condensation nucleus particle
counter
• Venturi throat introducer
• Surface allergen sampling
