Research Spotlight - Evaluation of an electrostatic precipitator in mitigating the transmission of airborne viruses in experimentally infected pigs

Reprinted as posted on Swine in Minnesota blog May 27, 2025

The publication being shared is from the Torremorell lab exploring a new technology aiming at preventing the transmission of airborne viruses. The full publication is available in open access on the Veterinary Research Journal.

Methods:

• Electrostatic precipitators (ESP) are air cleaning devices removing particles from the air and depositing them on collection surfaces.
• 4 pigs were inoculated with either PRRSV or influenza A virus (IAV) and placed into two isolators linked through an air duct.
• The air then went through an ESP prior to reaching 2 naive pigs placed in a third isolator
• The study lasted until the sentinel pigs were confirmed positive or the study went on for 10 days, whichever came first.
