Perhaps the most important part of Leppin's comments are these: "This shouldn't be surprising given the fact that OEMs ensure that the filter manufacturers meet their specifications. However, the use of high efficiency filters comes with a price. These HEPA filters have an extremely high pressure drop (134 to 412 Pa). This, in turn, increases fuel burn as the recirculating fans have to work hard to drive the required airflow through the filter and back to the aircraft cabin. To reduce the pressure drop, the authors suggested the use of nanofiber media to replace glass fiber media. In their tests, the authors tests found that the filter material change pressure drop was reduced from 84.7 Pa/(cm/s) to less than 28.5 Pa/(cm/s). There are some challenges to using nanofiber media as it would need to formulated to ensure they do not post a fire and smoke risk." High level Hepa filters in aircraft require additional fuel burn to push air through them. It is suggested utilizing a nanofiber material will be much more efficient. The downside is with nanofibers there is a challenge (risk) of smoke and fire. Who has been working on fire retardants? Who has close ties to producers of nanofibers?

Thanks for posting this intel Candu! It speaks to the point I was trying to make with my post a couple weeks ago. Test perameters are all equal such as the same sealed classroom, same amount of pathogens introduced etc From the PR: The testing was performed at the NRC's unique bioaerosol testing facility designed and built specifically for testing wet aerosolized droplets, which is the primary mechanism for the spread of disease in an indoor setting. The question to ask is, does the results, of using a Zenguard coated Merv 8 filter compare directly with the Merv 13 filter treated with Zenguard. If the air in the classroom can be 100% exchanged/cleaned of all pathogens in a similar timeframe, then why use the Merv 13 filter with its additional power consumption requirements. From the PR: The result of providing cleaner air for indoor spaces is consistent with current global indoor air quality initiatives and environmental goals of reducing energy consumption." The savings in terms of energy and filter costs (Merv 13 down to Merv 8) to real estate owners of all public indoor spaces is significant. On top of that the testing is Government of Canada sponsored and carried out. I suspect this is the reason it took so long to complete Phase II testing. I also suspect this is the reason LMS Technologies only did testing on Merv 8 rated filters! I believe when we see the complete data from the NRC Phase II testing, there will be some nice surprises! Welcome to 2023 folks, the furure looks very bright! VH
