"In thinking about the program, the one thing I wish I would have said is that engineers should not be afraid to challenge accepted assumptions. It took 2 years to overcome the "#droplet dogma".
We have always "assumed" that a #HEPA air cleaner with a 99%+ efficiency on <1 um particles would outperform a #MERV13 with 50% efficiency. We were wrong as shown here.

Awesome info there. Do you have a link to a study on this?
Great info, just would have liked to see a deeper dive on it from a paper or something. Thank you for sharing!
@BE This is from Jim himself (on his Twitter feed), hence my crediting of him. He didn't give a link.
