New device better traps viruses, airborne pathogens
Date:2/22/2013

Washington University engineering researchers have created a new type of air-cleaning technology that could better protect human lungs from allergens, airborne viruses and ultrafine particles in the air.

The device, known as the SXC ESP, was created by a team led by Pratim Biswas, PhD, the Lucy & Stanley Lopata Professor and chair of the Department of Energy, Environmental & Chemical Engineering in the School of Engineering & Applied Science.

A recent study of the device, published in Applied and Environmental Microbiology, found that it could help to prevent respiratory and viral infections and inhalation-induced allergic reactions more efficiently than existing filter-based systems.

Asthma, a chronic respiratory disease that can be triggered by inhaling allergens, pollen, pet dander and other particles, is one of the most costly health-care expenses in the United States at more than $50 billion.

"Because many people in developed countries spend the majority of time indoors, properly maintaining indoor air quality is an absolute necessity to protect public health," Biswas says.

The new device incorporates soft X-ray irradiation as a component of the electrostatic precipitation process currently used to remove large particles from airflows. By incorporating the soft X-ray enhanced electrostatic precipitation technology, the researchers were able to ensure very efficient charging of the particles over a broad range of sizes and their capture in the SXC ESP.

They exposed mice with compromised immune systems to the downstream air stream passing through the unit that contacted infectious viruses, allergens, anthrax, smallpox and other particles in the air. The sensitive mice survived, indicating that the SXC ESP was very effective in removing these biological agents from the air.

"Traditional air cleaners can trap viruses or other toxic particles in the filter, where they linger and grow," Bi
