What mask is the best to protect against coronavirus?

Scientists from Duke University (USA) tested the effectiveness of 14 different types of masks to reduce the spread of COVID-19 and compiled a list of the best masks to protect against coronavirus. World mass media writes about it.

According to experts, the best way to prevent the virus is the N95 respirators, usually used by medical professionals. Three-layer surgical masks and cotton masks, which can be made with own hands, also protect well.

During the experiment, scientists sprayed aerosols through the fabric, and then using a laser and a mobile camera recorded the amount of emissions entering the environment during the conversation. Each model was checked ten times.

According to experts, cloth bandages and bandanas were the most useless, and fleece masks-gaiters are even considered to be dangerous.
