It is recommended not to – the virus might be on the filters – but It is far more likely that airborne transmission will occur. The odds of transfer from the filters to the hands and then to the mucosal… Read More »How to keep little fingers out of the filters? Or – can students touch the filters?
This is a great question! Two part answer. First part is that it’s actually two different technologies. Bulbs are usually used to clean items in a sealed container in a hospital. Hospitals use UVGI to clean the air. And it… Read More »Wouldn’t it work better if we added UVC bulbs under the shroud like hospitals do?
Maybe 🙂 . This is page is really just a collection of ideas to help inspire YOU. It was conceived as a combination of physics (aerosols), biology (lungs), and math (large number conversions). All parts are meant to be used… Read More »Science Project – do you have any ideas?
Better. NYC’s CADR for smoke was 129. The Corsi/Rosenthal Box CADR was 132. And that was with MERV 10/11 filters. The Corsi/Rosenthal Box should be made with MERV 13 filters, so will test even higher. These measurements are in process.
No: Measured by Underwriter’s Laboratories, Inc. Smart Air has been doing the same thing since 2013 – only 5 had issues, most likely issues with the fan motor itself, not the load. There were no actual fires.
That study did not include the risk of reaersolization (blow back up in the air) of dried respiratory aerosols that will have settled on the ground. You will give a little in efficiency to gain safety. http://poppendieck.com/IAQ/COVID19%20FAQ.html
Yes – it removes aerosols from the air. How well does it work? Very well. “It is the most cost effective purifier on the chart.” – this evaluation is from Dr. Zaatari, who regularly publishes an easy-to-understand chart that simplifies… Read More »Does the Corsi/Rosenthal Box work?
