The secret on Mask Package. What BFE, PFE, and VFE means?

Medical Mask is one of the most effective and basic protection for disease spreading. However, it has been an essential component in our daily life, and it’s also become an option for daily outfit concern. Except for colors and patterns on it, how to choose a correct mask? The values of BFE, PFE and VFE might tell us some secret. What they are?

BFE is for Bacterial Filtration Efficiency. It means this mask will block particles with 3 micrometers (㎛), and it helps to stop bacteria, pollen, and droplet.

PFE is for Particle Filtration Efficiency. It means this mask will block particles with 0.1~0.5 micrometers (㎛), and it helps to stop Flu Virus and others with larger particle.

VFE is for Viral Filtration Efficiency, It means this mask will block particles with 0.1 micrometers (㎛), and it helps to stop most virous particles.

If the mask package is with BFE 95%, that means this mask can block 95% particles of which in 3 micrometers (㎛). The numbers of PFE and BFE are in the same concept. Therefore, higher value is better selection.
