Effectiveness of Different Masks at Stopping COVID-19 Droplets

Lisa C. Settlement & Community News, Updates

It’s not always true to say that any mask or facing covering is better than nothing.

A recent study done by a group of researchers at Duke University analyzed the effectiveness of different types of face masks. The study suggests that:

  • N95 masks (fitted, without valves) are the most effective at stopping COVID-19 droplets;
  • Three-layer surgical masks and homemade cotton masks also perform well;
  • Knitted masks and bandanas provide less protection;
  • Fleece neck gaiters increase the number of droplets expelled, so wearing no mask is better than wearing a fleece mask
From the most effective to the least effective:
  1. Fitted N95 masks
  2. Surgical masks
  3. Cotton masks
  4. Knitted masks
  5. Bandanas
  6. No masks
  7. Fleece masks
