The masks, which cover the nose and mouth, are often made from a flimsy material and aren’t fitted to the face. In other words, spaces and gaps can form around the cheeks and edges of the mouth, making it easy for air to move in and out.Surgical masks are typically used by surgeons to protect their patients from their mouth-borne germs — but “those masks don't work to prevent inhaling diseases.
This 3 ply material is made up from a melt-blown material placed between non-woven fabric. The melt-blown material acts as the filter that stops microbes from entering or exiting the mask. Most surgical masks feature pleats or folds. Commonly, 3 pleats are used allowing the user to expand the mask so it covers the area from the nose to the chin. There are 3 different ways to secure the masks. The most popular is the ear loop, where a string like material is attached to the mask and placed behind the ears. The other is the tie-on and the head band. The tie-on straps consist of four non-woven straps that are tied behind the head.
A more protective mask, known as an N95 respirator, may be more effective, said Schaffner. But, he noted, a non-medical professional using this mask is likely not using it correctly, doing little to prevent the spread of illness or inhaling a disease.
Certainly ,all the masks must do the test items what the masks test standards specified.each country has its own test standards for mask.As part of required testing laboratory instruments for surgical mask and respiratory mask a masks manufacturer needs following test with instruments required as per EU,ASTM,NIOSH,EN standard.there is a list for masks manufacturers to refer to:
Air Flow Resistance Tester;
Mask Combustion Tester;
Medical Face Mask Differential Pressure Tester;
particle filtration efficiency tester
Surgical Mask Tester Bacterial Filtration Efficiency (BFE) Detector ;
Antisynthetic blood penetration tester
