14 Types of Masks are Tested to Find the Best Preventive One and those that Multiply Chances of Virus Infection

There is a new wave of infection being experienced all over the world. This is due to the relaxed rules. Face masks will go a long way in helping prevent the virus from spreading and there are many types of masks out there.

It is important to distinguish those that will make you more defenseless to infections and those that truly shield you from the viruses. Of home-made masks, cotton masks are precautionary. Neck fleeces are the worst ones. They double the chances of infection as they break down large droplets into tinier droplets. The next worst face coverings are the knitted ones.

By far, the N95 non-valved masks are the best preventive masks. The valved N95 mask is preventive to the wearer but not to those close to him. Surgical masks with three layers are good at preventing coronavirus infections.

The method used to test the effectiveness of any mask to prevent coronavirus infections is easy and doable. It was used by a group of experts from North Carolina at Duke University. It involves the use of a laser pointer and camera. Particles produced by a person are brightened to show how effective the mask can be. That is how the conclusions on the best and the worst masks were made.
