Allergens and other contaminants in public places
adversely affect many people. Poor air quality results in reduced productivity
at work, and airplane travelers are often exposed to diseases from other
passengers. One potential solution is through the use of personal air
ventilation systems, or PAVs; however, the current technology lags the need
Through funding from the Syracuse
Center of Excellence, Propulsive Wing, LLC, in collaboration with Allred &
Associates, Inc. and Syracuse University, has developed a unique personal air
purifier system to reduce contaminant and allergen exposure, delivering clean,
fresh air to an individual. This methodology utilizes an individualâ€™s thermal
plume to enhance cleaning effectiveness, is compact, quiet, and consumes only 2
Watts of power. In addition to air quality improvement, the unit interfaces
with a computer for power, control, and performance monitoring.
Multiple prototypes were
manufactured and tested for cleaning effectiveness and power consumption.
Integration within an office workspace was a key design driver. Digital control
circuitry was developed along with custom Windows interface software, including
a built-in function to simulate the random fluctuations present in natural
Using analytical, computational, and experimental tools, a patent-pending personal air purifier system was developed to reduce contaminant exposure in the breathing space of an individual. Computational fluid dynamics
simulations of the personal environment and the Personal Breeze device were used to optimize the design.he
Building Energy and Environmental Systems Laboratory at Syracuse University. Specialized particle and VOC filter media was developed through the course of this work. Results show dramatic air quality improvement and targeted delivery of this filtered air to the user, with contaminant levels reduced by 50% or more at the breathing zone. Prototype units were built and tested by the Building Energy and Environmental Systems Laboratory at Syracuse University. Specialized particle and VOC filter media was developed through the course of this work. Results show dramatic air quality improvement and targeted delivery of this filtered air to the user, with contaminant levels reduced by 50% or more at the breathing zone.
to the development of the Personal Breeze prototypes, a filter testing device was designed and built with the unique
ability to evaluate up to 5 different particle filter media samples
simultaneously. This piece of equipment includes
an inlet pre-filter, ports for particle generation and seeding into a mixing box, pressure drop measurement
across each sample filter,
upstream and downstream particle sampling, flow rate measurement, and flow control through each sample.
completion of the funded work, Propulsive Wing, LLC has continued work on the
product, filing additional patent applications related to adding heating and
cooling, humidification and dehumidification, and several other capabilities to
the system. Additionally, a scaled-up version for use as a room air purifier
was developed. This larger floor-standing model is similar to products
currently available at major retail stores in form and function; however, by
utilizing the patent-pending filter configuration developed for the smaller
Personal Breeze, this unit provides twice the performance (in terms of flow
rate and level of filtration) as currently available units.
This technology provides increased air quality via a personal air ventilation and purification system that can result in increased productivity at work and less exposure to diseases and allergens in public places.

Dr. Kummer gave a presentation on September 29, 2008 at
the SyracuseCoE Symposium on Environmental & Energy Systems. Also presented
at the conference were two posters on the project, as well as demonstrations of
the latest Personal Breeze
prototypes and the filter testing
device. Dr. Kummer also gave a presentation on December 4, 2008 for the Center
of Excellence Scientific Advisory Committee at the Renaissance Hotel in Syracuse.
