Delta, BC, June 4, 2008 - AirTest Technologies (TSXV:AAT) is pleased to announce that the AirTest PM2200 Air
Quality Monitor has been selected by Buildings Magazine as one of the Top 100 products for 2008 and is featured
in the June issue of Buildings Magazine. Buildings Magazine (“Buildings”) is the leading publication targeting
commercial building owners and operators in North America.

Throughout the year, the Buildings editorial staff takes note of intriguing and innovative products and
services that can greatly assist facility managers and owners with their development, construction,
modernization, management, and operations responsibilities. Based on discussions with industry suppliers,
experiencing many products firsthand, and culling through mounds of literature and websites, Buildings
Magazine selected the AirTest PM2200 Desktop Indoor Air Quality (“IAQ”) monitor as worthy of recognition.

The AirTest PM2200 Personal IAQ Monitor is a desktop tool that allows building owners and facilities
professionals to investigate energy-saving opportunities and improve indoor air quality in their buildings. This
affordable air-quality indicator monitors carbon dioxide (CO2), humidity, and temperature, and can also function as
a clock/calendar. According to Buildings Magazine “This monitor is maintenance free and requires no calibration
– plus, it’s about 25 percent less expensive than similar devices on the market.” The Buildings top 100 products
are featured in the June issue of the Magazine and also can be viewed on the Buildings web site at

“ Wherever there is a thermostat in a building today, there could be a CO2 sensor that saves energy and
provides ongoing feedback to optimize building operation. This is now a standard in Green and
Sustainable Buildings.” said George Graham, President of AirTest.. “The AirTest PM2200 is a critical part
of our strategy to provide a simple, inexpensive tool that can demonstrate to all building operators and
occupants the value of using CO2 level readings to measure ventilation and better understand building
operation.” added Graham.
