From the article I posted in this thread:

“For nanometer-sized particles, which can easily slip between the openings in the network of filter fibers, electrostatic attraction predominates the removal of low mass particles which are attracted to and bind to the fibers. Electrostatic filters are generally most efficient at low velocities such as the velocity encountered by breathing through a face mask.”

That's an interesting point, but completely irrelevant in this discussion. NONE of the masks suggested for use by the public against Covid-19 are electrostatic filters, nor do any of them have any significant electrostatic filtering capability.
