B2 Mask is very breathable for a respirator or face mask. However, it will not be as comfortable as wearing no mask at all. B2 Mask exceeds the recommended breathing resistance required by NIOSH for Filtering Facepiece Respirators. Light breathing (walking, desk work, driving) through B2 Mask will feel easier than heavy breathing (long flights of stairs, hard labor). If breathability is your top priority, consider purchasing B2 Filter Lite.
