Mitigating the spread of respiratory infections in indoor spaces
Hello HN, Almost 15 years into being a (rather quiet) user of HN, I am thrilled to write my first Show HN post! Early in the pandemic, we looked to devise a system that would drastically reduce the risk of spreading Covid-19 when people gathered in a room. The system would need to disinfect the air rapidly to keep the concentration of virions in the space low enough so the risk of cross infection would be drastically cut [1]. It became clear that an effective system would need to draw air away from the breathing space so that the exhaled air from an infected individual would not impinge upon…

In plain words
This system reduces respiratory infection spread in indoor spaces by capturing exhaled air away from the breathing zone and rapidly disinfecting it before recirculation. Designed during the pandemic, it lowers airborne virion concentration to minimize cross-infection risk when people gather indoors. The technology draws air from occupied spaces through a disinfection stage that inactivates pathogens like SARS-CoV-2, preventing buildup of infectious particles in shared rooms.

Hello everyone, My son loves Hacker News, so I am using his account. I love innovation and technology. With the restrictions due to Coronavirus from practicing in my clinic. I created a system that replaces the air in my office in 20 seconds. Those vacuums are also filled with UV-rods inside to kill any viruses. The air is release below the office in a 2-3 foot basement, which is also filled with UV rods. https://youtu.be/UfYt1w156QA https://youtu.be/UpO8WXOlgcQ (side-by-side) Given how much my son enjoys Hacker News I thought you would all enjoy it. Here are…
