Did you know that wearing a fleece Neck Gaiter or Neck Warmer as they are also known as (#11) is actually worse than not wearing a Face Mask at all?
A study was done at Duke University to find the most and the least effective Face Mask. 14 Face Masks were tested to see the number of droplets let out when speaking. Unsurprisingly, the N-95 (#14) was the most effective in the study. In 2nd place was the disposable surgical mask (#1).
Masks made out of cotton (numbers 3, 6, 7, 8, 9, 10 and 13) all performed about the same and are better options than not wearing a mask at all.
And coming in dead last was the Neck Warmer (#11) which is actually lets out MORE droplets than not wearing at all. Coming in second last was the Bandana (#12) which only offered slightly more protection than no mask at filtering particles.
