The Comfo Classic Respirator is an improved version of the Comfo II Respirator, featuring new SoftFeel? facepiece material, which increases the comfort factor dramatically. A result of extensive materials research by MSA, SoftFeel material is an exclusive new formulation that improves the pliability and softness of both Hycar rubber and silicone-the two facepiece materials available with Comfo Classic Respirators. Like earlier Comfo? respirator models, the Comfo Classic Respirator features a unique face seal design that gives wearers an exceptional fit. Principle(s) of Operation When the wearer inhales, contaminated air enters and flows through the cartridges, which removes the contaminants from the air stream, so the wearer breathes in clean, fresh air. Approvals and Standards Requiring only routine filter replacement, the Comfo Classic Respirator is approved by the National Institute for Occupational Safety and Health (NIOSH) for use against a variety of respiratory hazards.
