KMT three-layer mask
N95 3D Respiratory Mask without Nano Respi Valve (Rima) Small Size Pack of 25
These masks contain a nano layer between their protective spunbond layers.
The mask trapping efficiency of 0.3 microns of these masks is about 95% and a slight pressure drop (easier to breathe than other masks).
The smaller size of this mask is suitable for 10 to 18 year olds (teenagers or women with thin and small faces) and makes the mask more fixed on the face.
