It has a great filter Electrostatic Media that can be rated with 98.86% efficiencies at least 0.3 microns.
It works by protecting you from breathing in harmful particles that can cause lung and body disease, like the much-feared coronavirus(COVID-19/NCOV 19) droplet >0.3 microns. Also, it works by blocking small particles and disease.
An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles.
The N95 designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 micron) test particles.
If properly fitted, the filtration capabilities of N95 respirators exceed those of face masks. Technically block 95% virus, however even a properly fitted respirator does not 100% completely eliminate the risk of illness or death.
Comparing Surgical Masks and Surgical N95 Respirators
The FDA regulates surgical masks and surgical N95 respirators differently based on their intended use.
A surgical mask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment. These are often referred to as face masks, although not all face masks are regulated as surgical masks. Note that the edges of the mask are not designed to form a seal around the nose and mouth.
An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. Note that the edges of the respirator are designed to form a seal around the nose and mouth. Surgical N95 Respirators are commonly used in healthcare settings and are a subset of N95 Filtering Facepiece Respirators (FFRs), often referred to as N95.
The similarities among surgical masks and surgical N95 are:
- They are tested for fluid resistance, filtration efficiency (particulate filtration efficiency and bacterial filtration efficiency), flammability and biocompatibility.
- They should not be shared or reused for many times.
