In the recent pandemic of coronavirus, the use of N95 respirators is immense. People are using N95 respirators every time they leave their houses. People are avoiding physical contact with anyone and are practicing social distancing.
The pandemic of coronavirus is widespread use in the whole world. Not a single country is safe from it. Many factories and industries have reduced the number of workers. Many have lost their jobs. In the United States of America, more than 200K people lost their jobs.
The situation the world is not different from the United States. The world under a financial crisis. Economies are being crushed to zero. Many underdeveloped countries have surrendered in front of the disease. People are not listening to the Government and the disease is out of their hands.
Once the disease is spread it multiplies quickly. It can spread through airborne particles in the form of fluid. This is the reason why N95 respirators are crucial in the cause. People are using N95 respirators whenever they are out in public. Also, people need to jeep distant to be more secure from the disease.
Disposable N95 respirators:
In 1860 during the pandemic. People started to use the N95 respirator as a protective shield against the disease. Many people were saved because of their usage. Many students and medical officials were studying N95 respirators. They came to the decision where they started that N95 respirators are for single use.
Then, N95 respirators were used and disposed of immediately. This continued in the pandemic of SARS, Influenza A, and B, Japanese Flu, and another pandemic. The world has always been under crisis either medical or financial.
N95respirators was declared disposable because of no filter pockets mainly. But, many models had filter pockets. These theories were made and changed by the officials many times.
Reusable N95 respirator:
The disposable N95 respirator was to be used for a maximum of 8 hours without removal. Till the pandemic of Coronavirus in 2019, N95 respirators were used and disposed of. Later in 2020 people started to reuse N95 respirators.
Many theories were presented by students of medical Universities. They represented how N94 respirators can be purified and reused. Many arguments were placed but later it was decided that N95 respirators can be reused if necessary or at will.
The methods to disinfect N95 respirators are strict and precise. Only four methods can be used to decontaminate a contaminated N95 respirator. These researched were very important in a time when people and doctors had run out of N95 respirators and were forced to use cloth made surgical masks.
The discovery made rounds in the history of the N95 respirator. The methods to purify N95 respirators are simple but cannot be used widely by the public. Many have introduced centers for cleansing N95 respirators.
Methods to purify N95 respirators:
Only four methods are tested affected in the purification process of N95 respirators. These methods are tested to cleanse the respirator without causing damage to the filter or polyester. The mask is tested after the purification process. The N95 respirator's charge is restored after purification for the first time.
The mask is also tested against germs after cleaning. The purification process is tested by the Food and Drug Administration or FDA. FDA had recommended the cleaning of N95 respirators instead of purchasing a new one.
N95 respirators can be contaminated by using ethanol spray and suspending the respirator in ethanol for sixty minutes straight. This process is a bit risky as it can damage the threads on the mask. After any type of damage, the mask cannot be
reused. These things are needed to be kept in mind while purifying the N95 respirator using ethanol.
This method cannot be used more than twice. After the second time, the mask is surely damaged because of the ethanol.
Dry heat is also one of the methods that can be used to purify the respirator including its filters. If the N95 respirator is given dry heat for ten to sixty minutes at 270°C the mask is surely purified. This is the recommended method to purify the N95 respirator among all the others. It is the safest and fastest method to purify the N95 respirator.
Germs and infections can be killed using heat and light mainly. Ultraviolet radiations are the most affected rays in this field. The students tested this method and found out the ultraviolet radiation can kill germs and disinfect the N95 respirator within an hour. This method ensures safety to the threads and the filter of the N95 respirator.
Ultraviolet radiation can purify the mask more than three times. But, it is better not to use the N95 respirator more than three times.
Vaporized Hydrogen peroxide:
Suspending the N95 respirator in hydrogen peroxide is yet another method that can be used to disinfect the N95 respirator. The method takes only ten minutes. It is a safe and quick method to purify the N95 respirator. Most people use this method to purify the make because it is instant.
N95 respirators can now be reused:
The biggest news yet from the medical side in 2020 is that N95 respirators can be reused after purification. Many doctors and nursing staff are happy with the discovery. They wanted to reuse their N95 respirator at the time of shortage but no method was then introduced. Soon the methods were launched and the purification of N95 respirators started in bulk.
It can be said that onwards N95 respirators will be reused instead of disposal. This discovery is huge and will save a lot of money for everyone.
