Fitted N95 masks performed very well, according to the study, by keeping droplets inside the mask

He said that each time while wearing a mask and uttering the phrase as researchers recorded droplets left on each mask

"We want to make sure you wear a mask that actually works,” Fischer said

The N95 fitted mask did well when it comes to protection

It sealed droplets and prevented them from leaving the mask

"The mask that stood out by far is the N95, the true fitted N95 mask," Fischer said

Fischer also said surgical masks "did a really good job."

Despite testing, the surgical mask didn’t do as well as the N95 because there are some gaps in the mask where droplets can escape

Researchers found that the two-layer cloth mask doesn’t give droplets much room to escape

"The cloth masks were pretty good," said Duke Dr

"Because the material is thin, it transmits lots of droplets," Fischer said

Lastly, and perhaps most surprisingly, the neck fleece had the highest number of droplets released – more than if no mask were worn

The researchers believe the material breaks larger droplets into smaller particles

"We put them on, and we saw what looks like more droplets coming out than without a mask," Fischer said

The Duke researchers said the goal is to help you make an informed decision on which mask you should use to protect yourself
