We are developing filtration technologies to benefit sustainable environment. The Center for Filtration Research (CFR) at the University of Minnesota, collaborating with 20 leading interna-tional filtration manufacturers and end users, was established to find filtration solutions to mitigate PM2.5 and other envi-ronmental pollutants. There are more than 15 on-going funda-mental and applied research projects on air, gas and liquid fil-tration.  Five projects will be presented: 1. reduction of aerosol concentration in classrooms to prevent virus transmissions; 2. electret and nanofiber media to improve filtration performance; 3. indoor air cleaning using gas purifiers, ionizers, and UV-C; 4. real-time image detection of airborne biological particles; 5. temperature resistant nano-scale membrane for enhanced ceramic wall-flow filter performance. Large scale air clean-ing towers are established in Xi’an and Yancheng in China to mitigate urban air PM2.5 and CO2 (Yancheng) with two addi-tional towers in Delhi, India. All these research and develop-ment activities are helping to improve sustainable environment.


Professor David Y. H. Pui is a Regents Professor and LM Fingerson/TSI Inc. Chair in Mechanical Engineer-ing at the University of Minnesota.  He is a member of the U.S. National Academy of Engineering (NAE) and the Director of the world-renowned Particle Technol-ogy Laboratory at the University of Minnesota.  He is also the Director of the Center for Filtration Re-search (CFR) consisting of >20 leading international filtration manufacturers and end users.  Dr. Pui has a broad range of research experience in aerosol and nanoparticle engineering and filtration technology, and has over 360 journal papers and 43 patents.  He has developed several widely used commercial aero-sol instruments for PM2.5 measurements. Dr. Pui has received many awards, including the Max Planck Re-search Award (1993), the Humboldt Research Award for Senior U.S. Scientists (2000), the Fuchs Memorial Award (2010) -- the highest disciplinary award con-ferred jointly by the American, German and Japa-nese Aerosol Associations. He served as President of the American Association for Aerosol Research (2000-2001), and President of the International Aerosol Research Assembly (2006-2010) consisting of 16 member associations from around the world.
