V-Type non-valved N99 Face Mask- Dark
V-type non-valved N99 Face Mask (Dark Model) are similar to FFP3 and N99 masks in terms of efficiency and pressure drop. These masks contain a nanofiber layer between the layers of their protective spunbond. Due to their special appearance, these masks have better breathability compared to medical face masks.
According to NIOSH standard filtering half masks, FNM Co. Ltd., can produce N99 class of respiratory face masks. Fish Type N99 masks, with an efficiency of 99% (0.3 micron particles) and pressure drop of less than 70 Pascal is suitable for public environment and without any toxic gases.
