The effect of surface charge, negative and bipolar ionization on the deposition of airborne bacteria

S. Meschke et al. – Journal of Applied Microbiology – Fall 2008

Bioaerosols can be generated by several means in an indoor setting, such as the ventilation or air conditioning systems, dust or shed skin disturbance, coughs and sneezes, among others. Although the contribution of air-borne micro-organisms to hospital or clinical-acquired infection has been the source of much debate in recent years, there is evidence suggesting that bioaerosols may play a greater role than previously believed….

Aerosol Surface Disinfection in a Pandemic World: Gas/Vapor-Phase Biocides, Fogging, and Electrostatic Spraying

Eugene C. Cole, DrPH – The Cleaning Industry Research Institute – Summer 2020

In the midst of the current human coronavirus pandemic, many building cleaning and sanitation practices and protocols have been improved in quality and frequency; they have also been upgraded from the use of anti-bacterial sanitizer products to more broad-spectrum disinfectants, capable of inactivating a variety of bacterial, fungal, and viral human pathogens. That has raised the question of the effectiveness of those disinfectants as gas-phase, vapor-phase, or fogging biocides because disinfection via the aerosol route can readily reduce the time and cost of application. The question remains, however: Can aerosol disinfection achieve the same or higher level of infectious disease risk eduction as the manual application of those products?….
