HALYARD PUREZERO® HM4 Non-Sterile Pouch Cleanroom Face Mask with Headbands – ISO Class 4+

HALYARD PUREZERO® HM4 Pouch Face Mask with Headbands is a non-sterile, three-layer cleanroom face mask designed for controlled environments where high filtration efficiency, wearer comfort and extended breathing space are required. The pouch-style design provides an expanded breathing chamber, making the mask suitable for longer wear in cleanroom and industrial environments. This product is intended for cleanroom and industrial use only and is not designed or certified for medical or surgical applications.

The mask is constructed from low-linting materials and features a SO SOFT® biocomponent inner lining to enhance comfort during extended use. A low-linting neck guard provides additional coverage and contamination control. The mask is double-bagged and recommended for use in ISO Class 4 and higher cleanroom environments, including GMP Grade B/C/D. Nylon elastic headbands ensure a secure and stable fit during use.
