Margaret, Monona & Peter Z and ALL,

As far as that Duke Study is concerned, the only NIOSH-Approved â??device" of the lot is #14, the 3M Health Care Particulate Respirator and Surgical Mask, Model #1860, N95 (TC - 84A-0006), which is a teal-blue color.

If you are unaware, NIOSH has specific requirements as to the identification and markings of all tested and certified (TC) and approved respiratory protection devices.

Please see the attached website site below for guidance and NIOSH shows pictorially what those requirements are on the last page.

As you scroll down, you may find some of â??Face masks and Alternativesâ?? or facsimiles thereof in the Duke Study.

Also and before you do that, please read NIOSHâ??s statement and bulleted items in the light blue-shaded rectangle on the first page.

If you have any questions, please let me know. Thanks!

Be Safe, Secure & Sound, Vigilant as Always and Well!

All MY Best,
