Proof of concept testing of a bead-on-string polyacrylonitrile nanofibrous air filter for indoor air cleaners

Indoor air quality of buildings is becoming even more important today, with the persistence of COVID-19 pandemic. A new type of air filter, based on bead-on-string polyacrylonitrile, offers high ultrafine particles removal (above 99%) as well as low pressure drop. Environmental and Power Solutions and Canada Water Technology eXchange are joining forces to undertake research to investigate options to control COVID-19 virus. The objective of this project is to develop a proof-of-concept testing protocol for the bead-on-string filter (BOSF), conduct the experiments of the BOSF samples at the Microcellular Plastics Manufacturing Laboratory (MPML) at the University of Toronto, analyze the performance and pressure drop, and identify commercialization potential and certification testing opportunities of the new filter.
