. Introduction
Over the years, numerous studies have been carried out to
measure the factors that influence the selection of hotel accommodation
by customers. Many researchers have identified that
cleanliness is the most important attribute influencing the decision

to deduce that good indoor air quality (IAQ) should also be an
important attribute for hotels. This is especially true as hotel guests
typically comprise a high proportion ofinternationaltravelers and a
good mix of dignitaries and officials who demand high IAQ. Equally,
inadequate IAQ invariably brings complaints (Bohdanowicz and
Martinac, 2002).
More recently, research findings have indicated that air pollutioninEast
andSouthAsiahas beendeterioratingdue to accelerated
economic expansion and population growth. Brauer et al. (2012)
found that there is a high concentration of fine particles (PM2.5)
in South and East Asia (annual averages >50 g/m3). PM2.5 is
