The rationale for double masking (spun polypropylene inner mask, two layer cotton outer) is based on an enhanced
mechanical filtration effect (extra layers) and an electrostatic charge being generated (triboelectric effect) by
dissimilar fabrics. CDC is conducting comparative studies of masking efficacy but this will likely be confined to
filtration measures. "Hard data" (epidemiological studies demonstrating decreased transmission and/or acquisition
of infection) are much more difficult and raise ethical concerns (re: control groups use of substandard or no PPE).
And no amount of data will convince people who are consumed by pandemic denialism and wish to rationalize their
pseudoscientific, sociopathic beliefs.

Good afternoon, all.
This morning Dr. Locke said that “there is a lot of evidence” to support double-masking.
Kindly provide that evidence in a reply to this email at your earliest convenience.
Thank you.
