Cleaner Air in Your Libraries

Dayton Metro Library Installs NPBI Technology

Dayton Metro Library is installing needlepoint bipolar ionization (NPBI) technology to improve the quality of the air in all its facilities. The technology is being added at all DML facilities, both new and vintage, by the end of 2020, through CARES Act funding.

“We’ll all breathe easier when COVID-19 is controlled with a vaccine, but in the meantime this technology kills not only the COVID-19 virus, but also clears other viruses, bacteria and spores from the air, providing healthier Libraries even after the pandemic is over,” said Tim Kambitsch, DML Executive Director.

NPBI technology cleans indoor air with a high concentration of positive and negative ions delivered through existing HVAC systems. The ions form bonds with particles in the air through a process called agglomeration. Pollutants, dust, dander, pollen, smoke and pathogens such as mold, bacteria and viruses in the air begin to cluster. Larger clusters of particles are easier for the HVAC system to safely filter out. Additionally, when ions come in contact with pathogens, they disrupt the pathogens’ surface proteins, rendering them inactive. This process is proven by independent laboratory testing to be both safe and effective, delivering clean indoor air without producing ozone or other harmful byproducts.

The Board of Library Trustees approved contractor Applied Mechanical to install the technology, manufactured by Global Plasma Solutions. Materials have been ordered and installation is expected to be completed systemwide by the end of the year. NPBI technology at the vintage Branch Libraries (Burkhardt, Madden Hills, Westwood, Northmont and Huber Heights) will be removed and reinstalled in the new buildings when they are constructed.

“Along with our mask requirement, social distancing, disinfecting, and curbside services, this technology will help to stop the spread of COVID-19,” said Kambitsch.
