Duke Study Finds Which Face Masks Are Most Effective

BOSTON (WBZ NewsRadio) — A new study out of Duke University tested out the effectiveness of different face coverings for preventing the spread of disease. Some coverings, it turns out, may be worse than not wearing a mask at all.

In the study, Duke researchers had participants speak into a box and say "stay healthy, people" while wearing a mask. Then, they used a laser to see how many droplets had been sprayed on the inside of the box.

As it turns out, bandanas and knit masks are not effective at all. Neck gaiters aren't as safe as previously thought. Droplets are dispersed into smaller particles, making them less safe than not wearing a face covering at all.

The unsurprisingly winner was the N-95 mask. Other effective masks include disposable surgical masks and homemade cotton masks.
