For Immediate Release                                         14 December, 2005


BURNABY, B.C. - QuestAir Technologies Inc. (AIM: QAR; TSX: QAR) announced today
that it has received purchase orders totaling C$1.8 million from ExxonMobil to
begin the construction of a prototype hydrogen purifier to be demonstrated at a
refinery.

QuestAir has been working with ExxonMobil Research and Engineering to develop a
large capacity pressure swing adsorption (PSA) system for use in oil refineries
and petrochemical plants. A prototype PSA plant will be tested at a refinery in
the second half of 2006.

The orders announced today cover a compressor to be included in the prototype
plant and related project management services. An order for long lead items
associated with the PSA is expected to be received in the next few weeks. The
remaining orders related to the prototype plant are expected upon the successful
completion of an ExxonMobil program review.

Jonathan Wilkinson, President and CEO of QuestAir said, "We continue to make
excellent progress with our development program with ExxonMobil Research and
Engineering. Procurement and construction of the prototype plant has now begun,
and our plans for the prototype test at a refinery are proceeding as planned."

About Pressure Swing Adsorption
QuestAir's gas purification technology is based on its proprietary innovations
in pressure swing adsorption (PSA) technology that solve some of the inherent
disadvantages of conventional PSA. Conventional PSA technology was introduced
commercially in the 1960s and today is applied extensively in the production and
purification of hydrogen, oxygen and nitrogen for industrial uses. QuestAir's
rapid-cycle PSA technology operates at significantly higher cycle speeds than
conventional PSA, resulting in a direct reduction in the size of equipment
required to purify a given volume of product gas

About QuestAir Technologies Inc.
QuestAir Technologies, Inc. is a developer and supplier of proprietary gas
purification systems for several large international markets, including existing
markets such as oil refining, biogas production and natural gas processing, and
emerging markets such as fuel cell power plants and fuel cell vehicle refuelling
stations. The Company has joint development agreements with Exxon Mobil Research
and Engineering Company and Shell Hydrogen, and a collaboration with FuelCell
Energy. QuestAir is based in Burnaby, British Columbia and its shares trade on
the AIM Market of the London Stock Exchange Plc. and on the Toronto Stock
