The rapid spread of the omicron-type means that many experts in medical and public health are urging Americans to adopt better masking protocols for protecting themselves and others from Covid-19. 

While masking techniques have improved since the outbreak, many people are still confused about what type of mask to wear. Medical experts are unanimous: Masks are a key component in stopping all forms of Covid-19 from spreading. The N95 Mask respirator by the National Institute for Occupational Safety and Health has been approved. 

Even though a simple face cover is better than no covering at all in some cases, better options exist now. As the omicron variant is more transmissible than the previous variants, wearing a mask is essential in helping to stop its spread, especially in areas that have high Covid-19 patients. 

Omicron should influence how mask usage changes 

Over the course, omicron has seen more changes in mask-wearing guidance. Experts agree that masking is essential due to the transmissibility high of the omicron variety. Omicron can be 2.7-3.7 times more easily transmitted to persons than the other variant. Although mild cases are common, cases are rising rapidly in heavily fully vaccinated regions also. The ability of the omicron to resist antibodies from the Covid-19 vaccines means additional preventive measures such as masks are back in the spotlight. 

Abraar Karn, a physician at Stanford University, stated to New York Magazine that cloth masks are not effective in filtering aerosols. These particles can escape from the infected person and then be inhaled easily if both of them wear cloth face coverings. 

He also claims that N95 respirators block these particles better than other types. This is due to the filter structure and electrostatic charge, which attracts and traps tiny aerosol particles. Also, the fit of the filter over the wearer’s mouth and nose is better than a cloth mask. These can leave large gaps at the sides, giving the infectious particles plenty of opportunities to escape. 

How can you get the best mask? 

Since the outbreak, the N95 masks have been the gold standard. They are the most effective in protecting against Covid-19. 

The N95’s intricate, irregular weave allows for superior filtration, trapping 95 percent of aerosol particles -- hence the "95” in N95. KN95s are also capable of filtering out 95 percent of particles. The K signifies that they were manufactured to conform to China's mask standards. 

Although cost is still a concern, N95s are generally priced at USD or two per disposable face mask. In addition, counterfeit respirators can pose an additional problem. 

High-quality respirators have been proven to be effective and fit well. It is worthwhile to do some basic testing of masks before you purchase. The mask should be fitted tighter as air can escape from the sides. Aerosols can still pass through the barrier. 

A surgical mask is a good alternative to N95 and KN95 respirators. The multiple layers of the mask are more effective than cloth masks. While surgical masks don't perform as well as N95 respirators (they use the same filters), they are just as effective. The fit of surgical masks is crucial because they aren't the same as N95 masks.
