Impact/Purpose:
This summary provides an update on EPA’s aerosol treatment research to evaluate technologies that are reported to reduce airborne virus concentrations. Results on the efficacy testing of two RGF Photohydroionization® (PHI) technologies against MS2 conducted in a large-scale aerosol test chamber with a recirculating HVAC system are summarized. These interim data are being made available to inform stakeholders, including OCSPP, OAR, transit agencies, and the general public, about the potential efficacy of using this product as part of a strategy to reduce airborne disease transmission.
Description:
This website update provides a summary of efficacy testing with the RGF Photohydroionization® (PHI) technology in a large aerosol test chamber with a recirculating HVAC system. The unit's efficacy was evaluated against aerosolized MS2 (a bacteriophage).
