- there are many misunderstandings what a mask can do and what not.
- especially in regards of virus protection a lot of incorrect information can be found.
- Here some basic clarifications:
- the virus is usually transmitted through droplets from sneezing or coughing.
- the vast majority of the droplets are less than 100 micron(0.1 micron) across.
- Surgical madks are designed to prevent large droplets passing from the wearer's mouth to another person.
- N95 respirators protect the wearer from breathing in particles bigger than 0.3 microns in diameter. When fitted correctly the respirators filter 95% of airborne particles.
- THIS MEANS VIRUS CAN PASS THROUGH ALL MASKS, SO ONLY THE PROBABILITY CAN BE REDUCED.
General Mask Construction.
- the primary layer is coated with hydrophobic chemicals is normally relative stiff, colouration has no functionality besides indication of the outer layer.
- the middle layer is normally fluffy with a high fiber density to provide a better filter filtration effect.
- the inner layer is soft and with antimicrobial protection to reduce the bad smell from human saliva.
