SMS technology (spunbond/meltblown/spunbond)
The combination of the fabric of spunbond (S) type and meltblown (M) type gives fabric of the SMS type (its structure comprises of two spunbond layers between which there is a meltblow layer, or of the SSMMS type (its structure comprises of three spunbond layers interlaid with two meltblown layers). The resulting composite fabric has excellent physical properties (strength, elasticity, abrasion, secondary tearing, tear strength etc.) and excellent barrier qualities preventing leakage of very fine particles and micro-organisms and aggressive liquid.

What is the difference between the PFF2 respirator and one with N95 certification? Respirators with PFF2 classification follow the Brazilian standard (ABNT / NBR 13698: 1996) and European and have a minimum filtration efficiency of 94%, while respirators with N95 classification follows the American standard and has a minimum filtration efficiency of 95%. Therefore, PFF2 and N95 respirators have equivalent protection levels.
