Summary

A laboratory setup was used to challenge a glass fiber media filter, a polymer fiber media filter, and a two-stage electrostatic precipitator (electronic air cleaner) with 100% ambient outside air for one year. Over the year, fractional efficiency measurements were made as well as microbial sampling to determine filter effectiveness on ambient viable bioaerosols. Both of the media filters demontrated greater than 90% effectiveness on fungi and bacteria bioaerosols. The electrostatic precipitator demonstrated initial efficiency of 95% or greater, which decreased over time as the device was overloaded.
