It’s not always true to say that any mask or facing covering is better than nothing.
- 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:
- Fitted N95 masks
- Surgical masks
- Cotton masks
- Knitted masks
- No masks
- Fleece masks
