N-95 respirator masks are the newest hot selling item for “flu preparedness”, but do they really work? Yes. And No. N-95 respirator masks were designed to protect healthcare workers from `airborne` illnesses like tuberculosis, chicken pox as well as the flu. They DO work under tightly controlled circumstances, however the general public is not likely to be in those tightly controlled circumstances, so they will likely not reap the benefits of them.
Face masks were first used throughout the 1918 flu epidemic as `protection` from the flu. It likely did not do a bit of good, but laws were enacted and people who didn`t put them on were considered “mask slackers” who could be fined, imprisoned or just ostracized. With the swine flu claiming a lot more victims in the US, people are starting to react by putting on masks again. But now, the greater technology N95 Mask For Coronavirus is all the rage.
The N-95 is not really your grandfather`s surgical mask or even the same as surgical masks worn by doctors and nurses today like you see in operating rooms. They may be specialized items that were designed to protect hospital workers against `airborne` illnesses like tuberculosis, chicken pox and influenza. Many of these are extremely small infectious particles that remain airborne after being exhaled by an infected person. We have seen lots of misinformation about these masks. Some claim that they work, some claim that they don`t. So what is the truth?
The reality is that N 95 respirators DO protect wearers against the flu- at the very least in theory and when used properly. The N 95 respirators ARE Airtight and Are created to protect the wearer from airborne particles as small as Mycobacterium Tubuculosis- approximately 45 nanometers in width or about 1/2 micron. The swine flu virus, by contrast, is nearly doubly large at approximately 80-120 nanometers. Inside the hospital setting when utilized by trained practitioners, as set by Centers for Disease Control guidelines, these masks are VERY EFFECTIVE at preventing transmission of those tiny particles
But there are several main reasons why the N-95 respirators are unlikely to work for your general public. The first reason is it is hard to obtain the right fit. Medical care workers who wear N95 Masks For Sale are told, “Here, put this on”. Surgical masks can be worn by anyone, anywhere for long periods of time. As shown by folks China wearing masks while riding bicycles to work or even jogging, they may be pretty comfortable and simple to use. But any adverse health care worker who uses an N-95 must actually go through a brief training session. First, the approximate correct size for your face is chosen and placed tightly to the face with 2 tight straps fitting onto the head. Second, the metal band on the nose bridge is smoothed down to obtain a tight fit. When a correct fit is approximated, the head is placed in to a large plastic tube to approximate a confined space. A trainer, normally a nurse, sticks a spray bottle right into a small hole and continuously sprays a saccharine solution into the plastic tube while the wearer turns the head from side to side or higher and down to make certain that you can find no air leaks. In the event the saccharine solution is tasted, then the good `fit` has not been obtained and the procedure is repeated with another sized mask until an airtight seal is obtained: sometimes hard for those with particularly small or large faces or individuals who have facial hair.
The second reason is that N 95 Respirators are uncomfortable, hot and tight. While a surgical mask can be worn for hours without any problems, an N-95 respirator becomes uncomfortable and claustrophobic even in a cool hospital room within just minutes. After looking after someone for even a quick while, the breath feels hot and uncomfortable and a lot commence to sweat- some people sweat PROFUSELY! Taking off the mask after wearing one for only a quick while feels as if you entered into a cool fresh breeze after just getting out of a sauna. Wearing one in an air conditioned theater while just sitting and watching a movie will be unbearable. Wearing one while riding a bicycle or while shopping could be just simply impossible.
Any mask- whether it be surgical or N95 Mask For Sale was created to be used for less than twenty minutes at the same time. This is because the mask itself will become saturated with condensation from exhaled breath. And once it is saturated, then this gaflvq filter size may be changed making the mask ineffective and potentially even trapping the offending viruses right against the wet mask- Right Near the Face!
So, while N-95 masks DO effectively protect health care workers from even one on one transmission of airborne contaminants including the flu, inappropriate usage by untrained lay folks real world circumstances would likely get them to ineffective and nullify the potential protective results of these effective filtration devices.
