There has been much confusion about protection in the midst of all the uncertainty surrounding COVID-19. Do you need to wear a mask when in public? What type of masks is required for healthcare workers and what kind? What is the difference between different types of masks?
According to your industry, local regulations, or state laws, masks and face covers may be required. It is important to know the differences between masks in order to determine what you actually need.
Experts agree that face masks reduce the spread of COVID-19. The chances of someone with the virus spreading to others drop if they wear a face mask. Wearing a mask on your face is also a way to protect yourself from COVID-19.
A face mask is a way to protect yourself and others from COVID-19. But not all face masks are created equal. It is important to understand which masks offer the best protection.
A KN95 mask made in USA is the equivalent of an N95 mask. However, it typically meets certifications only in China and not the United States.
The masks act as a barrier between the wearer and any particles or liquids in air. A KN95 and an N95 filter 95% of particles.
N95 masks usually have two straps that wrap around your head to provide a more secure fit. KN95 masks usually have ear loops.
The most important difference between products and services is whether they have been approved for use by National Institute for Occupational Safety and Health.
Masks used in healthcare must comply with all NIOSH regulations. However, the FDA temporarily allows masks to be used that are not NIOSH for medical applications.
Many users are most concerned about the percentage of particles that masks capture. This metric is the same for both N95 and KN95 respirator faces. Both masks can capture 95% of small particles (0.3 micron particles)
People will assume masks cannot capture particles smaller than 0.3 microns, since N95 and KN95 masks have a 95% rate of capturing 0.3 micron particles. It would make no sense that masks are effective in preventing virus transmission if that were true. It is actually much easier to capture particles smaller than 0.33 microns.
You can also consider other types of masks.
Surgical Masks are looser fitting and are designed to protect patients while blocking larger particles such as droplets or liquids that could contain germs.
Single-use face masks are thin and not for use in healthcare facilities.
The CDC asks everyone to reserve N95 surgical masks and surgical gloves for critical hospitals and businesses.
We often panic and want to act, but the easiest way to disinfect masks is to not do anything! Allowing masks to dry will kill any viruses.
Healthcare workers must know how long it takes to dry masks before they are safe. Viability is a crucial question because many studies determine whether viruses can be detected.
It is possible for viruses to remain detectable for a frighteningly long time. This has led to some amazing headlines about the virus's ability to persist. However, "detectable," is not the same as "viable". Mask users should be more concerned about "viable" because it means that it is still possible to infect others.
Researchers from the University of Hong Kong examined how viruses can infect people on different surfaces.
