For a type ii masks beneath this widespread, the cloth need to clear out enough of the aerosol particles containing the bacteria to reap a cfu discount of at least 98%. Astm international has an  with comparable bacterial filtering widespread to the ecu kind ii preferred however similarly makes use of a check aerosol 

 micrometre debris. The extent three widespread f2100 general calls for that these particles ought to be filtered out with at least ninety eight% efficiency. Neither the eu nor the astm preferred checks overall performance as worn, they just check the fabric — the difference being the air leakage. This is unique to personal safety device requirements such as n95 and ffp, which do check performance as worn. Surgical mask are product of a nonwoven fabric created the usage of a soften blowing system. 

They came into use within the sixties and in large part changed cloth facemasks in advanced international locations. The colored (generally dark blue, green, or every so often yellow) aspect of the masks (fluid-repellant layer) is to be worn outwards, and the white side (absorbent layer) inwards.
