JAKARTA, HARIANHALUAN.COM – The Centers for Disease Control and Prevention (CDC) insists that you do not buy N95 masks for personal use.
Launching CNN International, Saturday (11/21/2020) the CDC revealed that this type of mask is considered to be the most effective 95% for filtering all particles. However, this mask is specifically used for medical workers and other health workers.
Additionally, the N95 mask must be fitted to fit the unique facial contours of each doctor or nurse. The community is considered not having the expertise to put on this type of mask.
In response to this, Assistant professor of medicine in the division of infectious diseases at Emory University in Atlanta, Dr. Marybeth Sexton insists that be careful with the many masks in circulation, which are made similar to the N95 mask.
“Some of the N95 masks used by the community have exhalation valves in them,” he said. “They do make it more comfortable to wear, but they don’t protect the people around you. This can actually make things worse because it concentrates your breath into that valve. So we strongly recommend that people don’t wear masks that have exhalation valves,” he stressed. .
Rather than using N95 masks which are much more expensive, Harvard environmental health researcher Joseph Gardner Allen says cloth masks are quite effective in preventing transmission.
Then what types of masks can provide maximum protection? According to him, a good mask is made with at least two layers of cloth.
“You can use a minimum of 2 layers of masks, but three layers of masks are better,” said Allen.
According to him, avoid using a gaiter mask or what is known as a buff mask, unless this is all that’s available. In fact, a recent study said that this type of mask was ineffective.
“Apart from the level of filtration, the thing that must also be considered is the fit (size),” continued Allen. “You want the mask to go over the bridge of the nose, under the chin and over the face, placed along the skin. You want your breath to pass through the filter media and not out from the side,” he concluded.
